Field of the Invention

[0002] The invention is related generally to exercise devices utilizing elastic restraint straps and loops, and more particularly, to a unitary, self-contained exercise device that provides counter-balancing resistances to exercise the core muscles and legs of a user over a full range of motion in performing various physical activities, such as running, walking, cycling, skating, skiing, swimming and other like physical activities.2. Related Art

[0003] Today, running is one of the most popular forms of exercise in the United States. There are many benefits of running: improving cardiovascular fitness, building up strength, endurance, and stamina, burning calories and controlling weight, etc. Running may take several forms that include jogging or steady-state running that utilizes slow twitch muscles to build endurance and aerobic fitness, and sprinting which involve anaerobic workouts that improve muscle strength as well as speed and endurance. These two forms can be combined to improve the user's performance over time to overcome plateaus or sticking points in training.

[0004] For persons less athletically inclined, advanced in age, or undergoing rehabilitation of injuries or after surgery, these persons instead of running may prefer walking, which will still provide similar benefits as running but at a different level of effort and intensity. In general, training one's body to run or walk longer or faster takes time, patience, and perseverance in that these persons should train for the long term and not physically overstrain their bodies beyond their current physical capabilities. Many runners / walkers may hit an early plateau in their training plans or may suffer burnout, fatigue, or simply lose interest in any further training if they try to progress too rapidly.

[0005] Accordingly, many varieties of devices and apparatus have been developed to aid persons engaged in running, walking, bicycling, etc., or for that matter, any physical activity that utilizes large muscle groups such as core muscles and legs in a coordinated, repetitive cyclic pattern. Many of these apparatus and devices utilize resistance bands or elastic restraint straps to apply resistance to the core muscles or legs of the user while exercising. For example, a leg muscle training device comprising an elongated elastomeric and stretchable tether and a set of leg binders attached to each end of the tether is disclosed in U.S. Pat. No. 5,167,601 to Frappier, entitled Sprinter Leg Muscle Training Device and Method. In Frappier, stationary resistance is provided to a runner by a personal trainer firmly grasping one end of the tether or attaching it to a point of attachment. Polyurethane surgical tubing may be used for the tether.

[0006] There are also numerous apparatus utilizing treadmills with resistance bands or elastic restraint straps. For example, a treadmill with a frame connected at a rearward end of the treadmill wherein a resistance attachment having an end connected to a human body is affixed to the frame of the treadmill so as to exert a resistance force on the human body is disclosed in U.S. Pat. No. 6,123,649 to Lee et al., entitled Resistance Application for Connection to a Human Body. Another example of an apparatus utilizing a treadmill is found in U.S. Pat. No. 6,652,427 to Wroclawsky, entitled Treadmill Resistance Apparatus, which discloses an apparatus for use with a treadmill for exercising the legs and lower body of a user with an elastomeric member that attaches to the user.

[0007] Another common type of exercise apparatus utilizing resistance bands or elastic restraint straps are those that utilize either a waist belt or various harnesses with mating clips that are attached to a body of a user to establish anchor points, wherein elastic cords are attached to the mating clips and then connected to various straps or harnesses placed around various parts of the user's body, such as an elbow, arm, foot, thigh, etc. An example of such an exercise device is disclosed in U.S. Pat. No. 7,608,026 to Nicassio, entitled Device for Strengthening, Training, and Rehabilitating Isolated Muscle Groups Using Elastic Resistance Elements. A similar type of exercise apparatus that is directed a specific physical activity is disclosed in U.S. Pat. No. 7,314,437 to Frappier, entitled Training Harness for Athletic Hitting and Swinging Skills.

[0008] As these examples indicate, many of these exercise apparatus require additional elements that may render the exercise apparatus more cumbersome and thus less useful in practice as well as more expensive to produce. Moreover, an exercise apparatus may be usable only for running, walking, or the like, while another exercise apparatus may be designed for a different physical activity, such as hitting or swinging movements in baseball, softball, or golf, and may require additional elements making the exercise apparatus even more cumbersome and expensive to produce. In other words, an exercise apparatus should be able to be utilized by a user in as many different physical activities as practicable.

[0009] In view of the foregoing, there is an ongoing need for an exercise device that utilizes resistance bands or elastic restraint straps and loops that is unitary and self-contained in that it does not require additional elements or parts. It should also be easy and inexpensive to produce each such device so that each and every potential user will have an exercise device that exactly matches his or her present physical characteristics and capabilities and meets the needs of their intended training program. It would also be advantageous if the exercise device would be capable of being used in the performance of or training in numerous physical activities other than being limited simply to running, walking, or cycling.SUMMARY

[0010] To address the foregoing problems, in whole or in part, and / or other problems that may have been observed by persons skilled in the art, the present disclosure provides a unitary, self-contained exercise device comprising a plurality of resistance bands and / or elastic restraint loops straps to generate simultaneous counter-balancing tensions to the large muscle groups such as the core muscles and legs of a user while the user is undergoing various physical activities, together with two optional sub-assemblies consisting entirely of elastic loops and straps, one fitted to the lower legs of a user and the other fitted to the upper arms of the user, while using the unitary, self-contained exercise.

[0011] A unitary, self-contained exercise device in accordance with the invention is unitary and self-contained; that is, the exercise device is capable of being used by a user without any additional equipment or accessories and is customized and produced specifically for each user individually. Thus, there is “no one size fits all,” although there may be small, medium, and large sizes of the unitary, self-contained exercise device such that each fits a relatively large group of users.

[0012] The unitary, self-contained exercise device in accordance with the invention comprises the following: (a) an elastic waist loop or belt; (b) an elastic left thigh loop; (c) an elastic right thigh loop (d) an elastic left rear strap having a first end and a second end; (e) an elastic right rear strap having a first end and a second end; (f) an elastic left front strap having a first end and a second end; and (g) an elastic right front strap having a first end and a second end. All of the elastic loops and straps in an assembled unitary, self-contained exercise device may be sewn together where necessary (with bonded nylon or bonded polyester threads) or heat fused together.

[0013] In assembling the unitary, self-contained exercise device, the first ends of the elastic left rear strap and the elastic right rear strap may be anchored together and connected at the middle of the back of the elastic waist loop and then the second end of the elastic left rear strap may be connected to approximately the center of the rear of the left thigh loop and the second end of the elastic right rear strap may be connected to approximately the center of the rear of right thigh loop. To complete the assembly, the first end of the elastic left front strap may be connected to the front of the elastic waist loop, slightly offset to left of center, and the first end of the elastic right front strap may be connected to the front of right thigh loop, slightly offset to right of center. Likewise, the second end of the elastic left front strap may be connected to approximately the center of the rear of left thigh loop and the second end of the elastic right front strap may be connected to approximately the center of the front of the right thigh loop.

[0014] As for the material used for the elastic waist loop, the elastic left and right thigh loops, and the left and right rear and front straps, there are many types of material available from online wholesalers, such as, for example, DirecTex located in Commerce, California. The material may take the form of webbing, cord, or bungee. Elastic webbing may be made from nylon, polypropylene, or polyester and is available in widths that can range from ⅜″ to 4″. Elastic webbing may be braided, knitted, or woven, and one wholesaler recommends woven elastic for waistbands because woven elastic retains its width when stretched. As for the elastic straps, nylon and polypropylene webbing each have different weights as well as different widths and accordingly the exercise device can be produced with the desired resistive force by varying the thickness, weight, length, or width of the webbing. Industrial sewing thread is also available to provide the required strength for the sewn connections of the final exercise device.

[0015] In addition to the embodiment of a unified, self-contained exercise device described in the preceding paragraph, a user may also utilize a sub-assembly of elastic loops and straps to be fitted on the lower left and right legs of a user. Such sub-assembly comprises a lower elastic thigh loop and a lower elastic leg loop, which are connected by a pair of left and right elastic straps positioned along the left and the right sides, respectfully, of the user's leg. One end of a third elastic strap is attached at the center of the rear of lower elastic thigh loop and the other end is attached at the center of the rear of the lower elastic leg loop. The lower elastic thigh loop is fitted a few inches above the user's knee, and the elastic lower leg loop is fitted just below the largest part of the user's calf. There is a separate sub-assembly for the left leg and the right leg of the user and they are not connected to each other in any way, nor are they connected to the unitary, self-contained exercise device as described in the preceding paragraph.

[0016] A second such sub-assembly is disclosed, that is, an upper arm sub-assembly comprising an elastic lower arm loop and an elastic upper arm loop, which are connected by a pair of left and right elastic straps positioned along the left and the right sides, respectively, of the user's arms. One end of a third elastic strap is attached at the center of the elastic lower arm loop and the other end is attached at the center of the elastic upper arm loop. The elastic lower arm loop is fitted a few inches above the user's wrist, and the elastic upper arm loop is fitted just below the user's elbow. The third elastic strap may be slightly shorter than the other two elastic side straps such that when this upper arm sub-assembly is fitted to an arm of a user, this third elastic strap will impart a slightly greater tension to the user's upper arm. There is a separate upper arm sub-assembly for the left arm and the right arm of the user and they are not connected to each other in any way, nor are they connected to the core assembly unitary, self-contained exercise device as described hereinabove.

[0017] Once the desired webbing is selected, an exercise device can be produced as a unitary, self-contained exercise device that can be worn over athletic wear or under, the latter being useful when exercising outdoors or in inclement weather. In other embodiments, the unitary, self-contained exercise device can be integrated into athletic wear; as an example, the waistband may be incorporated into the waistband of a pair of running shorts, with the left and right elastic thigh loops sewn into the left and right pant legs, respectively, of the running shorts.

[0018] A method of using the unitary, self-contained exercise device in a particular physical activity, which may be sprinting or jogging, swinging a golf club or throwing a baseball, or even beginning physical therapy by walking, is also disclosed. Obviously, a serious experienced user in a particular physical activity may likely devise their own exercise program, perhaps with the help of a professional trainer. However, for the average user, whether for a recreational activity or rehabilitation, there are certain principles that may be applicable to utilization of a unitary, self-contained exercise device in accordance with the invention. An object of the invention, in general, is to help train a user to move his or her body, e.g., walk or run, faster than he or she normally does so that eventually he or she will be able to eventually run or move faster without the unitary, self-contained exercise device. As for other physical activities, such as swinging a golf club or a tennis racket, the desired improvement may be a faster speed of a golf ball struck from the head of the golf club or a tennis ball from the head of the tennis racquet.

[0019] In general, methods and techniques of utilizing a unitary, self-contained exercise device may incorporate techniques borrowed from high-intensity resistance or interval training, one of which is that training with a unitary, self-contained exercise device may be three times a week with alternative days of training without the unitary, self-contained exercise device or no training at all. In other words, training with a unitary, self-contained exercise device too hard and too often may slow down results and lead to injuries.

[0020] To avoid this, methods and techniques of utilizing a unitary, self-contained exercise in accordance with the invention device may include measuring the metrics of the performance of a physical activity. For example, a runner or bicycle rider wearing a unitary, self-contained exercise device generally just needs to measure his time over a specified course and compare times with the unitary, self-contained exercise device to times without the unitary, self-contained exercise device. For more complex physical activities, such as hitting a golf ball, the physical activity is more complex and there are more metrics that can be measured. An example of an aid in determining these metrics is the Swing-Caddy SC300i Launch Monitor, which can measure the carry / total distance, smash factor, launch angle, swing speed, apex (maximum height), and ball speed of a driven golf ball. The Launch Monitor is set up near the golf ball and sends the measurement data to an app on the user's cell phone. For other sports involving striking a ball or puck, another device that is available to measure ball speed and other metrics is the Pocket Radar™ Ball Coach Speed Training Tool and Radar Gun.

[0021] Other devices, systems, methods, features, and advantages of the invention will be or will become apparent to one with skill in the art upon examination of the following figures and detailed description. It is intended that all such additional systems, methods, features, and advantages be included within this description, be within the scope of the invention, and be protected by the accompanying claims.BRIEF DESCRIPTION OF THE FIGURES

[0035] In the following description of the preferred and various alternative embodiments, reference is made to the accompanying drawings that form a part hereof, and which is shown by way of illustration a specific embodiment in which the invention may be practiced. It is to be understood that other embodiments may be utilized, and various structural changes may be made without departing from the spirit and scope of this invention.

[0036] As shown in FIGS. 1A and 1B, a unitary, self contained exercise device, generally designated by the reference character 100, worn by a user generally designated by the reference character 110, wherein a front and a rear view of the user is shown. The unitary exercise device 100 comprises the following components: (a) an elastic waist loop 116; (b) an elastic left thigh loop 118; (c) an elastic right thigh loop 120; (d) an elastic left rear strap having a first end and a second end 128; (e) an elastic right rear strap having a first end and a second end 130; (f) an elastic left front strap having a first end and a second end 138; and (g) an elastic right front strap having a first end and a second end 140.

[0037] All of the elastic loops and straps of the assembled unitary, self contained exercise device of FIGS. 1A and 1B have been sewn together at the appropriate contact points (not shown) with industrial sewing thread, which may be nylon or polyester, where bonded polyester is advisable for applications involving high UV light, severe weather, or salt water. An example of a common stitching pattern is the “Box-X stitch,” which should be sufficient for most embodiments of the unitary exercise device. As noted earlier, each unitary, self-contained exercise device is tailor-made for a particular user and should fit snugly but not tightly on the user, with the elastic waist loop positioned basically around the waist of the user, generally, where a belt would be worn. The elastic thigh loops can be positioned approximately one and one-half to two inches above the knees of the user. If the user wishes to lessen the tension provided by the elastic rear and front straps, the elastic thigh loops can be refitted higher up on the legs of the user. In general, when wearing the unitary, self-contained exercise device, the user of FIGS. 1A and 1B should be aware of when and where the tension will be generated by the elastic rear and front straps when exercising with the unitary, self-contained exercise device, but the unitary, self-contained exercise device should remain firmly and comfortably in place on the body of the user.

[0038] Turning to FIGS. 2A and 2B, a front and left side perspective view, respectively, of the user 210 while running while wearing the unitary, self-contained exercise device 200 is shown. In FIG. 2B, as the left leg of the user 210 strides forward, tension is built up and stored in the elastic left rear strap 228, while at the same at the same time, a previously stored counter-balancing tension is dissipated from the elastic left front strap 230. Meanwhile, on the right side of the user 210, a similar process takes place, as the right leg of the user 210 strides forward as the left leg of the user 210 retracts.

[0039] The elastic left and right rear and front straps of the unitary exercise device 100 provide counter-balancing resistive forces to the front and rear of the left and right legs of the user 210 via the elastic left thigh loop 118 the elastic right thigh loop 220, respectively. This results in a bias toward a faster rate of movement of the legs of a user when performing the exercise, in this instance, running, in a controlled, repetitive manner over an extended period of time. That is, the unitary exercise device 100 is used as a type of high-intensity resistance interval training device, in order to improve speed, endurance, and stamina while subsequently running without the assistance of the unitary exercise device.

[0040] That is, the unitary, self-contained exercise devices 100 and 200 are designed to train the user to move faster in performing a particular physical activity using counter-balancing resistance assistance, which could be characterized as utilizing rebound energy or the trampoline effect to make the user perform faster than otherwise when training. Another method of high-intensity interval training is downhill running, which forces the user's body to move faster rate than he otherwise could do on his own. The disadvantage of downhill running is that this type of running is more prone to causing injuries because there is a tendency for the user to run too fast. In contrast, using the unitary, self-contained exercise device allows the user to utilize the resistance forces in more controlled manner that is more efficient and safer. Once the user removes the unitary, self-contained exercise device, muscle memory enables the user to run faster than previously without the unitary, self-contained exercise device.

[0041] FIG. 3A shows a front perspective view of another example of an implementation of a fully assembled unitary, self-contained exercise device 300 in accordance with the invention wherein all the components of the unitary, self-contained exercise device are attached to each other by industrial sewing threads (not shown). The unitary, self-contained exercise device 300 comprises an elastic waist loop 316, which may consist of a woven elastic nylon or polypropylene strap, having a length equal to the circumference of the waist of the intended user, together an additional 1-2″ such that the ends of the elastic waist strap can be sewn or heat-fused together. Once the elastic waist loop 316 is formed, the first ends of the left rear elastic strap 328 and the right rear elastic strap 330 are attached together and then both first ends are attached to the inside of elastic waist loop 316 in the center at the inside rear of elastic waist loop 316, at attachment point 314. The second ends of the left rear elastic strap 328 and the right rear elastic strap 330 are each attached on the outside at the center of the left elastic thigh loop 320 and on the outside at the center of the right elastic thigh loop 318, respectively.

[0042] The first end of the left front elastic strap 338 is attached to the front of the elastic waist loop 316 off-center in a leftward direction in alignment with a front center of the elastic left thigh loop 320, and a second end of the left front elastic strap 338 is attached to the front center of the elastic left thigh loop 318; and the first end of the right front elastic strap 340 is attached to the front of the elastic waist loop 316 off-center in a rightward direction in alignment with a front center of the elastic right thigh loop 318, and a second end of the right front elastic strap 340 is attached to the front center of the elastic left thigh loop 318.

[0043] FIG. 3B shows a front perspective view of an example of a lower leg sub-assembly 350 consisting of two elastic loops and three elastic straps configured to be fitted on each leg of a user while wearing the fully assembled unitary, self-contained exercise device 300 described in a preceding paragraph. This lower leg sub-assembly 350 consists of an elastic upper leg loop 352 and an elastic lower leg loop 354, whereby the elastic upper leg loop 352 is fitted at 1-1½ inches above the user's knee (or just below the elastic thigh loop 320 of FIG. 3a), and the lower leg loop 354 is fitted just below the largest part of the user's calf. The upper leg loop 352 and the lower leg loop 354 are connected by a pair of left and right elastic straps (364 and 368) positioned along the left and the right sides, respectively, of the user's leg. One end of the third elastic center strap 360 is attached at the center of the rear of the upper leg loop 352, and the other end is attached at the center of the rear of the lower leg loop 354.

[0044] When using the lower leg sub-assembly 350 together with a unitary, self-contained exercise device 300 (which use is optional), there is a separate lower leg sub-assembly 350 for each leg and they are not connected together. Nor are they attached in any way to the unitary, self-contained exercise device 300. The purpose of the lower leg sub-assemblies 350 (left and right) is to provide additional feedback from sensory neurons in the user's muscles and joints to his brain through his central nervous system. The unitary, self-contained exercise device 300 in general provides the same function but is also configured to provide counter-balancing tensions from its various elastic straps. In contrast, the lower leg sub-assemblies 350 need not directly provide such counter-balancing tensions, and accordingly, its elastic straps may be of a lesser width than the elastic straps of the unitary, self-contained exercise device 300, for example, approximately ⅛″.

[0045] FIG. 3C shows a top perspective view of an example of an upper arm sub-assembly 370 consisting of two elastic loops and three elastic straps configured to be positioned on each arm of a user wearing the fully assembled unitary, self-contained exercise device 300 described in paragraphs hereinabove. This sub-assembly includes an elastic lower arm loop 372 and an elastic upper arm loop 374, whereby the elastic lower arm loop 372 is fitted at approximately 1-1½ inches above the user's wrist, and the upper arm loop 374 is fitted just below the user's elbow. The elastic lower arm loop 372 and the upper arm loop 374 are connected by a pair of left and right elastic side straps 384 and 386 positioned along the left and the right sides, respectively, of the user's leg. One end of the third elastic center strap 380 is attached at the center of the front of the lower arm loop 372 and the other end is attached at the center of the front of the upper arm loop 374.

[0046] When using the upper arm sub-assembly 370 together with a unitary, self-contained exercise device 300 (which use is optional), there may be separate upper arm sub-assemblies 370 for each arm and they are not connected together. Nor are they attached in any way to the unitary, self-contained exercise device 300. Like the purpose of the lower leg sub-assembly 350, the purpose of the upper arm sub-assemblies 370 (left and right) is to provide additional feedback from sensory neurons in the user's muscles and joints to his brain through his central nervous system to a user of the unitary, self-contained exercise device 300, and accordingly, its elastic straps may be of a lesser width than the elastic straps of the unitary exercise device 300. With respect to the upper-arm sub-assembly 370, the third elastic center strap 380 may be shorter in length (not shown) such that when fitted to the arm of a user and stretched to the same length as the left and right elastic side straps 384 and 386, there will be additional tension applied to the user's arm by the third elastic strap 380.

[0047] FIG. 4 shows a right-side perspective view of another example of an implementation of a unitary, self-contained exercise device in accordance with the invention worn by a user while riding a stationary exercise bicycle with the unitary, self-contained exercise device 400 worn on the outside of the user's clothing. In this physical activity, the unitary, self-contained exercise device operates on the legs of the user in a fashion similar to that of a runner or walker as shown in FIGS. 2A and 2B. What this example illustrates is that a unitary, self-contained exercise device in accordance with the invention can be used with other exercise equipment, such as a bicycle or treadmill, without any additional equipment or accessories other than the unitary, self-contained exercise device itself.

[0048] FIG. 5A shows a schematic sketch of a front perspective view of another example of an implementation of a unitary, self-contained exercise device in accordance with the invention worn by a user while holding a golf club while addressing a golf ball, with the unitary, self-contained exercise device worn on the inside of the user's clothing as shown by dashed lines. In this view, the user is in a neutral position and there is no tension on the left and right rear and front elastic straps.

[0049] FIG. 5B shows a schematic sketch of a front perspective view of the user shown in FIG. 6A after completion of his backswing and prior to initiating his downswing. As the user (who is right handed) begins his backswing, there is a greater build-up of tension in the core muscles and leg on the left side of the user as he moves from the neutral position to the completion of the backswing.

[0050] FIG. 5C shows a schematic sketch of a right-side perspective view of the user shown in FIG. 5B after initiating his downswing and rotating his hips thereby increasing tension on his right side while decreasing on his left side where the swinging movement ends with follow through and maximum tension on the right side of the user's body. Thus the tension applied to the left and right side of the user's core and leg muscles trains these muscles to move faster and with more power. In this view, a lower leg sub-assembly 350 is shown fitted on the right leg of the user 510 with an elastic upper leg loop 352a positioned just above the user's knee and an elastic lower leg loop 354a positioned just below the largest part of the user's calf. On the user's right leg, an elastic side strap 364a is shown connecting the lower thigh loop 352a and elastic lower leg loop 356a (the left side elastic strap 368b and elastic center strap 360a are not shown). On the user's left leg, an elastic center strap 360b is shown connecting the lower thigh loop 352b and elastic lower leg loop 356b (the left and right elastic side straps 364b and 368b are not shown).

[0051] FIG. 5C also shows the user 510 fitted with an upper arm sub-assembly 370a worn under his clothing on his right arm and shown in dashed lines (a corresponding upper arm sub-assembly worn on his left arm is not shown). The upper arm sub-assembly 370a consists of an elastic lower arm loop 372a fitted just above the user's wrist, and connected to an upper arm loop 374a fitted just below the user's elbow. The elastic lower arm loop 372a and the upper arm loop 374a are connected by elastic side straps 384a and 386a (not shown). The third elastic center strap 380a is also shown connecting the elastic lower arm loop 372a and the upper arm loop 374a, by one end of the third elastic center strap 380a attached at the center of the front of the lower arm loop 372 and the other end at the center of the front of the upper arm loop 374.

[0052] Turning to FIG. 6, a block diagram of a method of utilizing a unitary, self-contained exercise device in accordance with the invention worn by a user to perform training of a particular physical activity is shown. The method starts in step 602, and in step 604 the user puts on his unitary, self-contained exercise device and determines if the unitary, self-contained exercise device fits snugly and comfortably with the desired tension in the left and right front and rear straps. In decision step 606, if the user determines that his unitary, self-contained exercise device needs adjustment, he then proceeds to step 608 where any necessary adjustments are made after which the user returns to decision step 606. These steps are necessary because each unitary, self-contained exercise device must be properly fitted to each individual user for the most effective use of the unitary, self-contained exercise device.

[0053] Once the user is satisfied with his unitary, self-contained exercise device in decision step 606, the process proceeds to step 610, where the user undergoes training with his selected exercise routine while wearing his unitary, self-contained exercise device. While performing his exercise routine, the user at the same time is measuring his performance for the exercise routine; for example, for basic running or cycling, the applicable metric typically is just the elapsed time to complete a specific distance. For measuring a golf swing, there is the aforementioned Swing-Caddy, and for crunches and sit-ups, the metric may be simply the number of repetitions performed within a specific time period.

[0054] The next step is optional step 612, which merely recommends or suggests that the user not repeatedly exercise using only the unitary, self-contained exercise device. In step 614, the user undergoes training with his selected exercise routine without wearing his unitary, self-contained exercise device while at the same time measuring his performance for the exercise routine. In decision step 616, the user looks at the metrics from exercising with and without the unitary, self-contained exercise device and makes a determination whether to continue with his current exercise program; if so, he continues back to step 610. Otherwise, the process ends at step 618, whereupon the user has several options, such as, for example, modifying his exercise routine or modifying his unitary, self-contained exercise device, e.g., by increasing the tension of the rear and front elastic straps.

[0055] In an example of a user utilizing a unitary, self-contained exercise device, a week-end type golfer used such a unitary exercise device in practicing his golf swing at a driving range. His practice routine was to hit approximately 50 golf balls while wearing the unitary, self-contained exercise device in a single practice session. Using a Swing-Caddy Launch Monitor, the user found that his driving distance with a driver improved from approximately 216 yards to approximately 260 yards. As expected, when practice time was reduced, the driving distance decreased to approximately 245 yards.

[0056] Moreover, it is understood that a unitary, self-contained exercise device may be utilized with a lower leg sub-assembly fitted to each leg of a user while performing the method described in FIG. 6. Likewise, the upper arm sub-assembly may also be fitted to either arm or both arms of a user while performing this method. In performing decision step 616 of the method, generally the user will find measurable improvement in the metrics when exercising with the unitary, self-contained exercise together with the lower leg sub-assembly and / or the upper arm sub-assembly.

Field of the Invention

[0002] The invention is related generally to exercise devices utilizing elastic restraint straps and loops, and more particularly, to a unitary, self-contained exercise device that provides counter-balancing resistances to exercise the core muscles and legs of a user over a full range of motion in performing various physical activities, such as running, walking, cycling, skating, skiing, swimming and other like physical activities.2. Related Art

[0003] Today, running is one of the most popular forms of exercise in the United States. There are many benefits of running: improving cardiovascular fitness, building up strength, endurance, and stamina, burning calories and controlling weight, etc. Running may take several forms that include jogging or steady-state running that utilizes slow twitch muscles to build endurance and aerobic fitness, and sprinting which involve anaerobic workouts that improve muscle strength as well as speed and endurance. These two forms can be combined to improve the user's performance over time to overcome plateaus or sticking points in training.

[0004] For persons less athletically inclined, advanced in age, or undergoing rehabilitation of injuries or after surgery, these persons instead of running may prefer walking, which will still provide similar benefits as running but at a different level of effort and intensity. In general, training one's body to run or walk longer or faster takes time, patience, and perseverance in that these persons should train for the long term and not physically overstrain their bodies beyond their current physical capabilities. Many runners / walkers may hit an early plateau in their training plans or may suffer burnout, fatigue, or simply lose interest in any further training if they try to progress too rapidly.

[0005] Accordingly, many varieties of devices and apparatus have been developed to aid persons engaged in running, walking, bicycling, etc., or for that matter, any physical activity that utilizes large muscle groups such as core muscles and legs in a coordinated, repetitive cyclic pattern. Many of these apparatus and devices utilize resistance bands or elastic restraint straps to apply resistance to the core muscles or legs of the user while exercising. For example, a leg muscle training device comprising an elongated elastomeric and stretchable tether and a set of leg binders attached to each end of the tether is disclosed in U.S. Pat. No. 5,167,601 to Frappier, entitled Sprinter Leg Muscle Training Device and Method. In Frappier, stationary resistance is provided to a runner by a personal trainer firmly grasping one end of the tether or attaching it to a point of attachment. Polyurethane surgical tubing may be used for the tether.

[0006] There are also numerous apparatus utilizing treadmills with resistance bands or elastic restraint straps. For example, a treadmill with a frame connected at a rearward end of the treadmill wherein a resistance attachment having an end connected to a human body is affixed to the frame of the treadmill so as to exert a resistance force on the human body is disclosed in U.S. Pat. No. 6,123,649 to Lee et al., entitled Resistance Application for Connection to a Human Body. Another example of an apparatus utilizing a treadmill is found in U.S. Pat. No. 6,652,427 to Wroclawsky, entitled Treadmill Resistance Apparatus, which discloses an apparatus for use with a treadmill for exercising the legs and lower body of a user with an elastomeric member that attaches to the user.

[0007] Another common type of exercise apparatus utilizing resistance bands or elastic restraint straps are those that utilize either a waist belt or various harnesses with mating clips that are attached to a body of a user to establish anchor points, wherein elastic cords are attached to the mating clips and then connected to various straps or harnesses placed around various parts of the user's body, such as an elbow, arm, foot, thigh, etc. An example of such an exercise device is disclosed in U.S. Pat. No. 7,608,026 to Nicassio, entitled Device for Strengthening, Training, and Rehabilitating Isolated Muscle Groups Using Elastic Resistance Elements. A similar type of exercise apparatus that is directed a specific physical activity is disclosed in U.S. Pat. No. 7,314,437 to Frappier, entitled Training Harness for Athletic Hitting and Swinging Skills.

[0008] As these examples indicate, many of these exercise apparatus require additional elements that may render the exercise apparatus more cumbersome and thus less useful in practice as well as more expensive to produce. Moreover, an exercise apparatus may be usable only for running, walking, or the like, while another exercise apparatus may be designed for a different physical activity, such as hitting or swinging movements in baseball, softball, or golf, and may require additional elements making the exercise apparatus even more cumbersome and expensive to produce. In other words, an exercise apparatus should be able to be utilized by a user in as many different physical activities as practicable.

[0009] In view of the foregoing, there is an ongoing need for an exercise device that utilizes resistance bands or elastic restraint straps and loops that is unitary and self-contained in that it does not require additional elements or parts. It should also be easy and inexpensive to produce each such device so that each and every potential user will have an exercise device that exactly matches his or her present physical characteristics and capabilities and meets the needs of their intended training program. It would also be advantageous if the exercise device would be capable of being used in the performance of or training in numerous physical activities other than being limited simply to running, walking, or cycling.SUMMARY

[0010] To address the foregoing problems, in whole or in part, and / or other problems that may have been observed by persons skilled in the art, the present disclosure provides a unitary, self-contained exercise device comprising a plurality of resistance bands and / or elastic restraint loops straps to generate simultaneous counter-balancing tensions to the large muscle groups such as the core muscles and legs of a user while the user is undergoing various physical activities, together with two optional sub-assemblies consisting entirely of elastic loops and straps, one fitted to the lower legs of a user and the other fitted to the upper arms of the user, while using the unitary, self-contained exercise.

[0011] A unitary, self-contained exercise device in accordance with the invention is unitary and self-contained; that is, the exercise device is capable of being used by a user without any additional equipment or accessories and is customized and produced specifically for each user individually. Thus, there is “no one size fits all,” although there may be small, medium, and large sizes of the unitary, self-contained exercise device such that each fits a relatively large group of users.

[0012] The unitary, self-contained exercise device in accordance with the invention comprises the following: (a) an elastic waist loop or belt; (b) an elastic left thigh loop; (c) an elastic right thigh loop (d) an elastic left rear strap having a first end and a second end; (e) an elastic right rear strap having a first end and a second end; (f) an elastic left front strap having a first end and a second end; and (g) an elastic right front strap having a first end and a second end. All of the elastic loops and straps in an assembled unitary, self-contained exercise device may be sewn together where necessary (with bonded nylon or bonded polyester threads) or heat fused together.

[0013] In assembling the unitary, self-contained exercise device, the first ends of the elastic left rear strap and the elastic right rear strap may be anchored together and connected at the middle of the back of the elastic waist loop and then the second end of the elastic left rear strap may be connected to approximately the center of the rear of the left thigh loop and the second end of the elastic right rear strap may be connected to approximately the center of the rear of right thigh loop. To complete the assembly, the first end of the elastic left front strap may be connected to the front of the elastic waist loop, slightly offset to left of center, and the first end of the elastic right front strap may be connected to the front of right thigh loop, slightly offset to right of center. Likewise, the second end of the elastic left front strap may be connected to approximately the center of the rear of left thigh loop and the second end of the elastic right front strap may be connected to approximately the center of the front of the right thigh loop.

[0014] As for the material used for the elastic waist loop, the elastic left and right thigh loops, and the left and right rear and front straps, there are many types of material available from online wholesalers, such as, for example, DirecTex located in Commerce, California. The material may take the form of webbing, cord, or bungee. Elastic webbing may be made from nylon, polypropylene, or polyester and is available in widths that can range from ⅜″ to 4″. Elastic webbing may be braided, knitted, or woven, and one wholesaler recommends woven elastic for waistbands because woven elastic retains its width when stretched. As for the elastic straps, nylon and polypropylene webbing each have different weights as well as different widths and accordingly the exercise device can be produced with the desired resistive force by varying the thickness, weight, length, or width of the webbing. Industrial sewing thread is also available to provide the required strength for the sewn connections of the final exercise device.

[0015] In addition to the embodiment of a unified, self-contained exercise device described in the preceding paragraph, a user may also utilize a sub-assembly of elastic loops and straps to be fitted on the lower left and right legs of a user. Such sub-assembly comprises a lower elastic thigh loop and a lower elastic leg loop, which are connected by a pair of left and right elastic straps positioned along the left and the right sides, respectfully, of the user's leg. One end of a third elastic strap is attached at the center of the rear of lower elastic thigh loop and the other end is attached at the center of the rear of the lower elastic leg loop. The lower elastic thigh loop is fitted a few inches above the user's knee, and the elastic lower leg loop is fitted just below the largest part of the user's calf. There is a separate sub-assembly for the left leg and the right leg of the user and they are not connected to each other in any way, nor are they connected to the unitary, self-contained exercise device as described in the preceding paragraph.

[0016] A second such sub-assembly is disclosed, that is, an upper arm sub-assembly comprising an elastic lower arm loop and an elastic upper arm loop, which are connected by a pair of left and right elastic straps positioned along the left and the right sides, respectively, of the user's arms. One end of a third elastic strap is attached at the center of the elastic lower arm loop and the other end is attached at the center of the elastic upper arm loop. The elastic lower arm loop is fitted a few inches above the user's wrist, and the elastic upper arm loop is fitted just below the user's elbow. The third elastic strap may be slightly shorter than the other two elastic side straps such that when this upper arm sub-assembly is fitted to an arm of a user, this third elastic strap will impart a slightly greater tension to the user's upper arm. There is a separate upper arm sub-assembly for the left arm and the right arm of the user and they are not connected to each other in any way, nor are they connected to the core assembly unitary, self-contained exercise device as described hereinabove.

[0017] Once the desired webbing is selected, an exercise device can be produced as a unitary, self-contained exercise device that can be worn over athletic wear or under, the latter being useful when exercising outdoors or in inclement weather. In other embodiments, the unitary, self-contained exercise device can be integrated into athletic wear; as an example, the waistband may be incorporated into the waistband of a pair of running shorts, with the left and right elastic thigh loops sewn into the left and right pant legs, respectively, of the running shorts.

[0018] A method of using the unitary, self-contained exercise device in a particular physical activity, which may be sprinting or jogging, swinging a golf club or throwing a baseball, or even beginning physical therapy by walking, is also disclosed. Obviously, a serious experienced user in a particular physical activity may likely devise their own exercise program, perhaps with the help of a professional trainer. However, for the average user, whether for a recreational activity or rehabilitation, there are certain principles that may be applicable to utilization of a unitary, self-contained exercise device in accordance with the invention. An object of the invention, in general, is to help train a user to move his or her body, e.g., walk or run, faster than he or she normally does so that eventually he or she will be able to eventually run or move faster without the unitary, self-contained exercise device. As for other physical activities, such as swinging a golf club or a tennis racket, the desired improvement may be a faster speed of a golf ball struck from the head of the golf club or a tennis ball from the head of the tennis racquet.

[0019] In general, methods and techniques of utilizing a unitary, self-contained exercise device may incorporate techniques borrowed from high-intensity resistance or interval training, one of which is that training with a unitary, self-contained exercise device may be three times a week with alternative days of training without the unitary, self-contained exercise device or no training at all. In other words, training with a unitary, self-contained exercise device too hard and too often may slow down results and lead to injuries.

[0020] To avoid this, methods and techniques of utilizing a unitary, self-contained exercise in accordance with the invention device may include measuring the metrics of the performance of a physical activity. For example, a runner or bicycle rider wearing a unitary, self-contained exercise device generally just needs to measure his time over a specified course and compare times with the unitary, self-contained exercise device to times without the unitary, self-contained exercise device. For more complex physical activities, such as hitting a golf ball, the physical activity is more complex and there are more metrics that can be measured. An example of an aid in determining these metrics is the Swing-Caddy SC300i Launch Monitor, which can measure the carry / total distance, smash factor, launch angle, swing speed, apex (maximum height), and ball speed of a driven golf ball. The Launch Monitor is set up near the golf ball and sends the measurement data to an app on the user's cell phone. For other sports involving striking a ball or puck, another device that is available to measure ball speed and other metrics is the Pocket Radar™ Ball Coach Speed Training Tool and Radar Gun.

[0021] Other devices, systems, methods, features, and advantages of the invention will be or will become apparent to one with skill in the art upon examination of the following figures and detailed description. It is intended that all such additional systems, methods, features, and advantages be included within this description, be within the scope of the invention, and be protected by the accompanying claims.BRIEF DESCRIPTION OF THE FIGURES

[0035] In the following description of the preferred and various alternative embodiments, reference is made to the accompanying drawings that form a part hereof, and which is shown by way of illustration a specific embodiment in which the invention may be practiced. It is to be understood that other embodiments may be utilized, and various structural changes may be made without departing from the spirit and scope of this invention.

[0036] As shown in FIGS. 1A and 1B, a unitary, self contained exercise device, generally designated by the reference character 100, worn by a user generally designated by the reference character 110, wherein a front and a rear view of the user is shown. The unitary exercise device 100 comprises the following components: (a) an elastic waist loop 116; (b) an elastic left thigh loop 118; (c) an elastic right thigh loop 120; (d) an elastic left rear strap having a first end and a second end 128; (e) an elastic right rear strap having a first end and a second end 130; (f) an elastic left front strap having a first end and a second end 138; and (g) an elastic right front strap having a first end and a second end 140.

[0037] All of the elastic loops and straps of the assembled unitary, self contained exercise device of FIGS. 1A and 1B have been sewn together at the appropriate contact points (not shown) with industrial sewing thread, which may be nylon or polyester, where bonded polyester is advisable for applications involving high UV light, severe weather, or salt water. An example of a common stitching pattern is the “Box-X stitch,” which should be sufficient for most embodiments of the unitary exercise device. As noted earlier, each unitary, self-contained exercise device is tailor-made for a particular user and should fit snugly but not tightly on the user, with the elastic waist loop positioned basically around the waist of the user, generally, where a belt would be worn. The elastic thigh loops can be positioned approximately one and one-half to two inches above the knees of the user. If the user wishes to lessen the tension provided by the elastic rear and front straps, the elastic thigh loops can be refitted higher up on the legs of the user. In general, when wearing the unitary, self-contained exercise device, the user of FIGS. 1A and 1B should be aware of when and where the tension will be generated by the elastic rear and front straps when exercising with the unitary, self-contained exercise device, but the unitary, self-contained exercise device should remain firmly and comfortably in place on the body of the user.

[0038] Turning to FIGS. 2A and 2B, a front and left side perspective view, respectively, of the user 210 while running while wearing the unitary, self-contained exercise device 200 is shown. In FIG. 2B, as the left leg of the user 210 strides forward, tension is built up and stored in the elastic left rear strap 228, while at the same at the same time, a previously stored counter-balancing tension is dissipated from the elastic left front strap 230. Meanwhile, on the right side of the user 210, a similar process takes place, as the right leg of the user 210 strides forward as the left leg of the user 210 retracts.

[0039] The elastic left and right rear and front straps of the unitary exercise device 100 provide counter-balancing resistive forces to the front and rear of the left and right legs of the user 210 via the elastic left thigh loop 118 the elastic right thigh loop 220, respectively. This results in a bias toward a faster rate of movement of the legs of a user when performing the exercise, in this instance, running, in a controlled, repetitive manner over an extended period of time. That is, the unitary exercise device 100 is used as a type of high-intensity resistance interval training device, in order to improve speed, endurance, and stamina while subsequently running without the assistance of the unitary exercise device.

[0040] That is, the unitary, self-contained exercise devices 100 and 200 are designed to train the user to move faster in performing a particular physical activity using counter-balancing resistance assistance, which could be characterized as utilizing rebound energy or the trampoline effect to make the user perform faster than otherwise when training. Another method of high-intensity interval training is downhill running, which forces the user's body to move faster rate than he otherwise could do on his own. The disadvantage of downhill running is that this type of running is more prone to causing injuries because there is a tendency for the user to run too fast. In contrast, using the unitary, self-contained exercise device allows the user to utilize the resistance forces in more controlled manner that is more efficient and safer. Once the user removes the unitary, self-contained exercise device, muscle memory enables the user to run faster than previously without the unitary, self-contained exercise device.

[0041] FIG. 3A shows a front perspective view of another example of an implementation of a fully assembled unitary, self-contained exercise device 300 in accordance with the invention wherein all the components of the unitary, self-contained exercise device are attached to each other by industrial sewing threads (not shown). The unitary, self-contained exercise device 300 comprises an elastic waist loop 316, which may consist of a woven elastic nylon or polypropylene strap, having a length equal to the circumference of the waist of the intended user, together an additional 1-2″ such that the ends of the elastic waist strap can be sewn or heat-fused together. Once the elastic waist loop 316 is formed, the first ends of the left rear elastic strap 328 and the right rear elastic strap 330 are attached together and then both first ends are attached to the inside of elastic waist loop 316 in the center at the inside rear of elastic waist loop 316, at attachment point 314. The second ends of the left rear elastic strap 328 and the right rear elastic strap 330 are each attached on the outside at the center of the left elastic thigh loop 320 and on the outside at the center of the right elastic thigh loop 318, respectively.

[0042] The first end of the left front elastic strap 338 is attached to the front of the elastic waist loop 316 off-center in a leftward direction in alignment with a front center of the elastic left thigh loop 320, and a second end of the left front elastic strap 338 is attached to the front center of the elastic left thigh loop 318; and the first end of the right front elastic strap 340 is attached to the front of the elastic waist loop 316 off-center in a rightward direction in alignment with a front center of the elastic right thigh loop 318, and a second end of the right front elastic strap 340 is attached to the front center of the elastic left thigh loop 318.

[0043] FIG. 3B shows a front perspective view of an example of a lower leg sub-assembly 350 consisting of two elastic loops and three elastic straps configured to be fitted on each leg of a user while wearing the fully assembled unitary, self-contained exercise device 300 described in a preceding paragraph. This lower leg sub-assembly 350 consists of an elastic upper leg loop 352 and an elastic lower leg loop 354, whereby the elastic upper leg loop 352 is fitted at 1-1½ inches above the user's knee (or just below the elastic thigh loop 320 of FIG. 3a), and the lower leg loop 354 is fitted just below the largest part of the user's calf. The upper leg loop 352 and the lower leg loop 354 are connected by a pair of left and right elastic straps (364 and 368) positioned along the left and the right sides, respectively, of the user's leg. One end of the third elastic center strap 360 is attached at the center of the rear of the upper leg loop 352, and the other end is attached at the center of the rear of the lower leg loop 354.

[0044] When using the lower leg sub-assembly 350 together with a unitary, self-contained exercise device 300 (which use is optional), there is a separate lower leg sub-assembly 350 for each leg and they are not connected together. Nor are they attached in any way to the unitary, self-contained exercise device 300. The purpose of the lower leg sub-assemblies 350 (left and right) is to provide additional feedback from sensory neurons in the user's muscles and joints to his brain through his central nervous system. The unitary, self-contained exercise device 300 in general provides the same function but is also configured to provide counter-balancing tensions from its various elastic straps. In contrast, the lower leg sub-assemblies 350 need not directly provide such counter-balancing tensions, and accordingly, its elastic straps may be of a lesser width than the elastic straps of the unitary, self-contained exercise device 300, for example, approximately ⅛″.

[0045] FIG. 3C shows a top perspective view of an example of an upper arm sub-assembly 370 consisting of two elastic loops and three elastic straps configured to be positioned on each arm of a user wearing the fully assembled unitary, self-contained exercise device 300 described in paragraphs hereinabove. This sub-assembly includes an elastic lower arm loop 372 and an elastic upper arm loop 374, whereby the elastic lower arm loop 372 is fitted at approximately 1-1½ inches above the user's wrist, and the upper arm loop 374 is fitted just below the user's elbow. The elastic lower arm loop 372 and the upper arm loop 374 are connected by a pair of left and right elastic side straps 384 and 386 positioned along the left and the right sides, respectively, of the user's leg. One end of the third elastic center strap 380 is attached at the center of the front of the lower arm loop 372 and the other end is attached at the center of the front of the upper arm loop 374.

[0046] When using the upper arm sub-assembly 370 together with a unitary, self-contained exercise device 300 (which use is optional), there may be separate upper arm sub-assemblies 370 for each arm and they are not connected together. Nor are they attached in any way to the unitary, self-contained exercise device 300. Like the purpose of the lower leg sub-assembly 350, the purpose of the upper arm sub-assemblies 370 (left and right) is to provide additional feedback from sensory neurons in the user's muscles and joints to his brain through his central nervous system to a user of the unitary, self-contained exercise device 300, and accordingly, its elastic straps may be of a lesser width than the elastic straps of the unitary exercise device 300. With respect to the upper-arm sub-assembly 370, the third elastic center strap 380 may be shorter in length (not shown) such that when fitted to the arm of a user and stretched to the same length as the left and right elastic side straps 384 and 386, there will be additional tension applied to the user's arm by the third elastic strap 380.

[0047] FIG. 4 shows a right-side perspective view of another example of an implementation of a unitary, self-contained exercise device in accordance with the invention worn by a user while riding a stationary exercise bicycle with the unitary, self-contained exercise device 400 worn on the outside of the user's clothing. In this physical activity, the unitary, self-contained exercise device operates on the legs of the user in a fashion similar to that of a runner or walker as shown in FIGS. 2A and 2B. What this example illustrates is that a unitary, self-contained exercise device in accordance with the invention can be used with other exercise equipment, such as a bicycle or treadmill, without any additional equipment or accessories other than the unitary, self-contained exercise device itself.

[0048] FIG. 5A shows a schematic sketch of a front perspective view of another example of an implementation of a unitary, self-contained exercise device in accordance with the invention worn by a user while holding a golf club while addressing a golf ball, with the unitary, self-contained exercise device worn on the inside of the user's clothing as shown by dashed lines. In this view, the user is in a neutral position and there is no tension on the left and right rear and front elastic straps.

[0049] FIG. 5B shows a schematic sketch of a front perspective view of the user shown in FIG. 6A after completion of his backswing and prior to initiating his downswing. As the user (who is right handed) begins his backswing, there is a greater build-up of tension in the core muscles and leg on the left side of the user as he moves from the neutral position to the completion of the backswing.

[0050] FIG. 5C shows a schematic sketch of a right-side perspective view of the user shown in FIG. 5B after initiating his downswing and rotating his hips thereby increasing tension on his right side while decreasing on his left side where the swinging movement ends with follow through and maximum tension on the right side of the user's body. Thus the tension applied to the left and right side of the user's core and leg muscles trains these muscles to move faster and with more power. In this view, a lower leg sub-assembly 350 is shown fitted on the right leg of the user 510 with an elastic upper leg loop 352a positioned just above the user's knee and an elastic lower leg loop 354a positioned just below the largest part of the user's calf. On the user's right leg, an elastic side strap 364a is shown connecting the lower thigh loop 352a and elastic lower leg loop 356a (the left side elastic strap 368b and elastic center strap 360a are not shown). On the user's left leg, an elastic center strap 360b is shown connecting the lower thigh loop 352b and elastic lower leg loop 356b (the left and right elastic side straps 364b and 368b are not shown).

[0051] FIG. 5C also shows the user 510 fitted with an upper arm sub-assembly 370a worn under his clothing on his right arm and shown in dashed lines (a corresponding upper arm sub-assembly worn on his left arm is not shown). The upper arm sub-assembly 370a consists of an elastic lower arm loop 372a fitted just above the user's wrist, and connected to an upper arm loop 374a fitted just below the user's elbow. The elastic lower arm loop 372a and the upper arm loop 374a are connected by elastic side straps 384a and 386a (not shown). The third elastic center strap 380a is also shown connecting the elastic lower arm loop 372a and the upper arm loop 374a, by one end of the third elastic center strap 380a attached at the center of the front of the lower arm loop 372 and the other end at the center of the front of the upper arm loop 374.

[0052] Turning to FIG. 6, a block diagram of a method of utilizing a unitary, self-contained exercise device in accordance with the invention worn by a user to perform training of a particular physical activity is shown. The method starts in step 602, and in step 604 the user puts on his unitary, self-contained exercise device and determines if the unitary, self-contained exercise device fits snugly and comfortably with the desired tension in the left and right front and rear straps. In decision step 606, if the user determines that his unitary, self-contained exercise device needs adjustment, he then proceeds to step 608 where any necessary adjustments are made after which the user returns to decision step 606. These steps are necessary because each unitary, self-contained exercise device must be properly fitted to each individual user for the most effective use of the unitary, self-contained exercise device.

[0053] Once the user is satisfied with his unitary, self-contained exercise device in decision step 606, the process proceeds to step 610, where the user undergoes training with his selected exercise routine while wearing his unitary, self-contained exercise device. While performing his exercise routine, the user at the same time is measuring his performance for the exercise routine; for example, for basic running or cycling, the applicable metric typically is just the elapsed time to complete a specific distance. For measuring a golf swing, there is the aforementioned Swing-Caddy, and for crunches and sit-ups, the metric may be simply the number of repetitions performed within a specific time period.

[0054] The next step is optional step 612, which merely recommends or suggests that the user not repeatedly exercise using only the unitary, self-contained exercise device. In step 614, the user undergoes training with his selected exercise routine without wearing his unitary, self-contained exercise device while at the same time measuring his performance for the exercise routine. In decision step 616, the user looks at the metrics from exercising with and without the unitary, self-contained exercise device and makes a determination whether to continue with his current exercise program; if so, he continues back to step 610. Otherwise, the process ends at step 618, whereupon the user has several options, such as, for example, modifying his exercise routine or modifying his unitary, self-contained exercise device, e.g., by increasing the tension of the rear and front elastic straps.

[0055] In an example of a user utilizing a unitary, self-contained exercise device, a week-end type golfer used such a unitary exercise device in practicing his golf swing at a driving range. His practice routine was to hit approximately 50 golf balls while wearing the unitary, self-contained exercise device in a single practice session. Using a Swing-Caddy Launch Monitor, the user found that his driving distance with a driver improved from approximately 216 yards to approximately 260 yards. As expected, when practice time was reduced, the driving distance decreased to approximately 245 yards.

[0056] Moreover, it is understood that a unitary, self-contained exercise device may be utilized with a lower leg sub-assembly fitted to each leg of a user while performing the method described in FIG. 6. Likewise, the upper arm sub-assembly may also be fitted to either arm or both arms of a user while performing this method. In performing decision step 616 of the method, generally the user will find measurable improvement in the metrics when exercising with the unitary, self-contained exercise together with the lower leg sub-assembly and / or the upper arm sub-assembly.
