[0046] The foregoing is a summary, and thus, necessarily limited in detail. The above-mentioned aspects, as well as other aspects, features, and advantages of the present technology will now be described in connection with various embodiments. The inclusion of the following embodiments is not intended to limit the disclosure to these embodiments, but rather to enable any person skilled in the art to make and use the claimed subject matter. Other embodiments may be utilized, and modifications may be made without departing from the spirit or scope of the subject matter presented herein. Aspects of the disclosure, as described and illustrated herein, can be arranged, combined, modified, and designed in a variety of different formulations, all of which are explicitly contemplated and form part of this disclosure.

[0047] Generally, use of a multitude of exercise machines involves many inconveniences such as those related to space constraints, financial burdens placed on individuals, and / or difficulty with setup. However, because many people desire a diverse workout regimen to target different muscle groups and achieve well-rounded fitness, oftentimes, many machines are needed. For example, accommodating a range of machines for strength training, flexibility, and specialized exercises can quickly clutter one's home or gym space. Furthermore, owning multiple machines can be expensive, not to mention the maintenance costs and regular upgrades that may be required. The fragmentation created in exercise equipment can also deter some from staying committed to their fitness journey, as the logistical challenges and costs associated with acquiring and maintaining various machines can make consistent exercise more challenging. Multi-configuration exercise devices described herein are utilized to solve these issues of space, convenience, and financial constraints.

[0048] The technical problems to be solved by the exercise devices and / or assemblies described herein are floor space constraints and using a plurality of devices to execute a plurality of various exercises. In some embodiments, the exercise devices / assemblies described herein solve the above technical problems by saving floor space in a gym facility, home gym, living room, office, etc. where the exercise device may be used, while also providing a user with a plurality of configurations to perform various exercises on or using the exercise device. In some embodiments, the exercise device is transitionable between two configurations, more than two configurations, a plurality of configurations, three configurations, four configurations, five configurations, or six configurations. In some embodiments, any of the configurations may be used with or without one or more pads or a plurality of pads that are couplable to the interface frame. Further, additional removable assemblies may be included to expand on the number of exercises covered. In some embodiments, the multi-configuration exercise device may interface with a leg exercise assembly. In some embodiments, the leg exercise assembly may further include other removable assemblies to create additional configurations for further exercises (e.g., weighted hamstring curls, weighted quad exercises, belt squats, and / or cable adapters for weight systems.

[0049] Multi-configuration exercise devices described herein include an interface frame operatively coupled to a base frame. Multi-configuration exercise devices described herein include at least one hinged portion or point between the interface frame and base frame opposite an adapter site for a leg exercise assembly. For example, a leg exercise assembly may be reversibly couplable to a first end portion of an interface frame or a base frame, while the hinged portion may be on a second end portion of the interface or the base frame, opposite the first end portion. Said still another way, the leg exercise assembly may be on a first side of a latitudinal axis, and the hinged portion may be on a second side of the latitudinal axis, opposite the first side. For example, the interface frame may decline or incline, relative to the base frame, about the at least one hinged portion or point. Multi-configuration exercise devices contemplated herein include a variety of configurations with different interface frame heights and orientations, with respect to the base frame. Additionally, multi-configuration exercise devices described herein may include a multitude of configurations achieved by removing one or more pads or coupling one or more pads to the interface frame and / or the base frame. The various configurations of interface frame heights and orientations, with respect to the base frame, have been contemplated to be combined with any pad configuration. The contemplated configurations are intended for a multitude of exercises.

[0050] In accordance with 37 CFR 1.57, the entirety of International Patent Application PCT / US24 / 11560, filed Jan. 15, 2024, is hereby expressly incorporated by reference into this provisional patent application for all purposes. This incorporation is made to provide details pertinent to the understanding, operation, and implementation of inventions described and claimed herein, and to supplement the disclosure content of this application.

[0051] FIGS. 1 and 2 illustrate a leg exercise assembly 100. The leg exercise assembly 100 includes an interface mechanism 114, a support column 110, a first beam 112, and a second beam 108. The support column 110 may be coupled to the interface mechanism 114. The first beam 112 may include a first pair of pads 106a, 106b. The first pair of pads 106a, 106b may be operatively coupled to the first beam 112 such that a position of the first pair of pads 106a, 106b is adjustable with respect to the first beam 112. The leg exercise assembly 100 may include a weight horn. The weight horn may be on the first beam 112 and / or the second beam 108. In some embodiments, the first beam 112 may include a weight horn 116 such that weights can be removably coupled to the first beam 112. The second beam 108 may include a second pair of pads 102a, 102b. The second pair of pads 102a, 102b may be operatively coupled to the second beam 108 such that the position of the second pair of pads 102a, 102b is adjustable with respect to the second beam 108. The support column 110 may include a third pair of pads 104a, 104b. Post 109 may be rigidly coupled to the first beam 112 at a first angle 118 (shown in FIG. 2) so that the second beam 108, which slides over or shaped to receive post 109, is removably coupled to the first beam 112 also at the first angle 118. Alternatively, the second beam 112 may be directly and rigidly coupled to the first beam 112. First angle 118 may be about 55 to about 145 degrees; about 65 to about 135 degrees; about 75 degrees to about 125 degrees; about 85 degrees to about 115 degrees; etc. The first beam 112 may be hingedly or rotatably coupled to the support column 110 at hinge 160.

[0052] As shown in FIG. 3A, the leg exercise assembly 100 removably couples to a multi-configuration exercise device 120. The leg exercise assembly 100 includes one or more coupling features to couple the assembly 100 to the multi-configuration exercise device 120. As shown in FIGS. 3A, 3B, and 4, the interface mechanism 114 may include a slot bracket 126 which defines a slot 128. As shown in FIGS. 10 and 11, the multi-configuration exercise device 120 may include a threaded pin 152. The slot 128 of the slot bracket 126 may slip onto the threaded pin 152. As such, tightening the threaded pin 152, when the slot bracket 126 is slipped onto the threaded pin 152, may at least partially couple the interface mechanism 114 of the leg exercise assembly 100 to the multi-configuration exercise device 120. As shown in FIGS. 8-11, a multi-configuration exercise device 120 may optionally include a first weight horn 150a and a second weight horn 150b coupled to the base frame 125. As shown in FIG. 13, a weight horn 150 (e.g., a first or second weight horn) may both include a post portion 156 and a stud portion 158. The post portion 156 may include a diameter 210 greater than the diameter 212 of the stud portion 158. The stud portion 158 may be threaded and may couple to the base frame 125 of the multi-configuration exercise device 120 by threading the stud portion 158 into a female thread portion (not shown) of the base frame 125. In some embodiments, as shown in FIG. 5, the interface mechanism 114 may include a tube 153. For example, the tube 153 may be a rectangular tube. The tube 153 (shown in FIG. 5) may define a first pair of holes near a first end 154 of the tube 153, including an upper hole 130 and a lower hole 132. As shown in FIG. 12, the upper hole 130 may include a diameter 202 greater than the diameter 200 of the lower hole 132. In some embodiments, the holes are concentric to one another with a shared center point. As shown in FIG. 5, the holes 132, 130 may have offset center points, however, the holes 130 must be able to retain at least a post portion of a weight horn 150a. The diameter 202 of the upper hole 130 may be greater than the diameter 210 of the post portion 156a of the first weight horn 150a. The diameter 200 of the lower hole 132 may be greater than the diameter 212 of the stud portion 158 of the first weight horn 150a but less than the diameter 210 of the post portion 156a of the first weight horn 150a. The tube 153 may define a second pair of holes near a second end 157 of the tube 153, including an upper hole 134 and a lower hole 136. As shown in FIG. 12, the upper hole 134 may include a diameter 202 greater than the diameter 200 of the lower hole 136. The diameter 202 of the upper hole 134 may be greater than the diameter of the post portion 156b of the second weight horn 150b. The diameter 200 of the lower hole 136 may be greater than the diameter 212 of the stud portion 158 of the second weight horn 150b but less than the diameter 210 of the post portion 156b of the second weight horn 150b. As such, the first weight horn 150a may be placed within the first pair of holes of the interface mechanism 114 and coupled to the base frame 125 of the multi-configuration exercise device 120, and the second weight horn 150b may be placed within the second pair of holes of the interface mechanism 114 and coupled to base frame 125 of the multi-configuration exercise device 120. The use of the first weight horn 150a and / or the second weight horn 150b may be used alone or in combination with the slot bracket 126 to removably couple the leg exercise assembly 100 to the multi-configuration exercise device 120. Although leg exercise assemblies are shown herein, any accessory (e.g., different types of straps or frame extending devices to provide resistance at different directions / angles, etc.)may use the interface mechanisms described herein to removably attach an accessory to an exercise device.

[0053] FIG. 10 shows a multi-configuration exercise device 120 without a leg exercise assembly 100 coupled to the device 120. FIGS. 3A, 3B, 8, and 9 illustrate the leg exercise assembly 100 coupled to the multi-configuration exercise device 120. The orientation and angle of the interface frame 111 (shown in FIG. 8) may be adjusted to interface (i.e., the adjustable interface frame) accordingly with the leg exercise assembly 100, for example, orienting the interface frame 111 in an incline and / or about horizontal or declined toward the ground to interface with the leg exercise assembly 100. A user may sit on the pads 123a, 123b (although two pads are shown, one pad may be used or more than two pads, for example, three pads may be used) on the end 127 (shown in FIGS. 9 and 10) of the multi-configuration exercise device 120, place their legs over the third set of pads 104a, 104b (i.e., positioning pads 104a, 104b underneath the user's knee) and place their legs under the first set of pads 106a, 106b (i.e., positioning pads 106a, 106b above or on top of the ankle of the user), such that the user may perform leg extensions with weight resistance based on the amount of weight added to the weight horn 116. Alternatively, the user may remove the semi-cylindrical pad 129 (shown in FIG. 9), lie face down on the multi-configuration exercise device 120, place their legs over the third set of pads 104a, 104b (i.e., positioning pads 104a, 104b above their knees, under their thighs), and place their legs under the second set of pads 102a, 102b, such that the user may perform leg curls with weight resistance based on the amount of weight added to the weight horn 116.

[0057] FIGS. 6 and 7 illustrate an embodiment of a multi-configuration exercise device 900 in an example configuration. The configuration shown in FIG. 6 may be used, for example, by a user to perform abdominal exercises (e.g., sit-ups), hamstring exercises (e.g., glute-ham development), and / or lower back exercises (e.g., 90-degree back extensions). The device 900 includes a base frame 125 and an interface frame 111 operatively coupled together. When the base frame 125 is laid upon a surface (e.g., the plane defined by the horizontal axis 996 and the normal axis 929), such that the longitudinal axis 960 of the base frame 125 is approximately parallel to the surface, and with gravity acting approximately normal to the surface, the base frame 125 rigidly supports and stabilizes the device 900. The base frame 125 may be operatively coupled to the interface frame 111 via a support beam 902. Support beam 902 may be hingedly coupled to the base frame 125 using coupling 969, and the support beam 902 may be hingedly coupled to the interface frame 111 using coupling 962. The support beam 902 may be further coupled to the interface frame 111 using a first strut 904. The first strut 104 may be hingedly coupled to the support beam 902 using coupling 966, and the first strut 104 may be hingedly coupled to the interface frame 111 using coupling 967. The support beam 902 may be further coupled to the base frame 125 using a second strut 906. The second strut 106 may be hingedly coupled to the support beam 902 using coupling 964, and the second strut 106 may be hingedly coupled to the base frame 125 using coupling 270. Couplings 967, 962, 964, 966, 969, 270 may allow rotation adjustment in rotation directions 940 and 942 (shown in FIG. 7). The interface frame 111 may optionally include a plurality of pads: pad 908, pad 910, cylindrical pad 914, and cylindrical pad 914. Additionally, the interface frame 111 may include one or more handles 924. The base frame 125 may optionally include one or more wheels 918 and one or more weight pegs 921. The height 930 (shown in FIG. 7) and orientation of the interface frame 111 may be manipulated with respect to the base frame 125.

[0058] FIG. 7 illustrates the multi-configuration exercise device 900 in an expanded configuration. For example, the height 930 of the device 900 shown in FIG. 7 may be about 0.75 m to about 1.25 m; about 0.80 m to about 1.20 m; about 0.90 m to about 1.10 m; etc. Orientation of the interface frame 111 is with respect to the base frame 125, which may be between the longitudinal axis 968 of the interface frame 111 and the longitudinal axis 960 of the base frame 125, or the absence thereof (i.e., if the longitudinal axis 968 of the interface frame 111 is approximately parallel to the longitudinal axis 960 of the base frame 125). For example, the interface frame 111 may be rotated with respect to a plane defined by the horizontal axis 996 and the vertical axis 994 in rotation direction 940, such that the interface frame 111 is in an incline. An incline exists when the second angle 934 (shown in FIG. 7) is greater than the first angle 933 and the degree value of incline is the differential between second angle 934 and the first angle 933. For example,

[0061] In some aspects, the techniques described herein relate to an exercise device including: a leg exercise assembly including: a first beam coupled to a second beam at a first angle, a weight horn coupled to the first beam, a support column coupled to an interface mechanism and hingedly coupled to the first beam, wherein the interface mechanism is configured to removably couple to another exercise device, a first pair of pads coupled to the first beam, and a second pair of pads coupled to the second beam; and a multi-configuration exercise device removably coupled to the leg exercise assembly, the multi-configuration exercise device includes an adjustable interface frame.

[0062] In some aspects, the techniques described herein relate to an exercise device including: a leg exercise assembly including: a first beam, a weight horn, a support column coupled to an interface mechanism and hingedly coupled to the first beam, wherein the interface mechanism is configured to removably couple to a multi-configuration exercise device, and a first pair of pads coupled to the first beam; and the multi-configuration exercise device removably coupled to the leg exercise assembly, the multi-configuration exercise device includes an adjustable interface frame to couple to the interface mechanism.

[0063] In some aspects, the techniques described herein relate to a leg exercise assembly, including: a first beam; a weight horn coupled to the first beam; a support column coupled to an interface mechanism and hingedly coupled to the first beam, wherein the interface mechanism is configured to removably couple to a multi-configuration exercise device; and a first pair of pads coupled to the first beam.

[0064] In some aspects, the techniques described herein relate to a leg exercise assembly, including: a first beam; a support column coupled to an interface mechanism and hingedly coupled to the first beam, wherein the interface mechanism is configured to removably couple to a multi-configuration exercise device that is declinable and inclinable about a hinge portion opposite the interface mechanism; and a first pair of pads coupled to the first beam. When the second angle 934 is about 45 degrees and the first angle 933 is about 20 degrees, the resulting incline is about 25 degrees. The interface frame 111 incline may be greater than about 0 degrees (i.e., the longitudinal axis 968 of the interface frame 111 being approximately parallel to the longitudinal axis 960 of the base frame 125) to about 90 degrees; greater than about 0 degrees to about 60 degrees; greater than about 0 degrees to about 45 degrees; etc. Inversely, the interface frame 111 may be rotated with respect to a plane defined by the horizontal axis 996 and the vertical axis 994 in rotation direction 942, such that interface frame 111 decline is created. Decline exists when the second angle 934 (shown in FIG. 7) is less than the first angle 934 and the degree value of decline is the differential between second angle 934 and the first angle 933. For example, when the second angle 934 is about 20 degrees and the first angle 933 is about 45 degrees, the resulting decline 25 degrees. Decline may be greater than about 0 degrees (i.e., the longitudinal axis 968 of the interface frame 111 being approximately parallel to the longitudinal axis 960 of the base frame 125) to about 90 degrees; greater than about 0 degrees to about 60 degrees; greater than about 0 degrees to about 45 degrees; etc. If the length 954 of the first strut 904 is reduced, the third angle 970 between the first strut 904 and the interface frame 111 is increased, while the first angle 933 between the interface frame 111 and the support beam 902 is decreased. Inversely, if the length 954 of the first strut 904 is increased, the third angle 970 between the first strut 904 and the interface frame 111 is decreased, while the first angle 933 between the interface frame 111 and the support beam 902 is increased. If the length 956 of the second strut 906 is reduced, the fourth angle 936 between the second strut 906 and the base frame 125 is decreased, and the second angle 934 between the base frame 125 and the support beam 902 is decreased. Inversely, if the length 956 of the second strut 906 is increased, the fourth angle 936 between the second strut 906 and the base frame 125 is increased, and the second angle 934 between the base frame 125 and the support beam 902 is increased. Additionally, if the length 954 of the first strut 904 is reduced, the interface frame 111 can be pitched about the coupling 962 (shown in FIG. 6) in rotation direction 940. If the length 954 of the first strut 904 is increased, the interface frame 111 can be pitched with respect to a plane defined by the horizontal axis 996 and the vertical axis 994 about the coupling 962 (shown in FIG. 6) in rotation direction 942. Additionally, if the length 956 of the second strut 906 is reduced, the support beam 902 can be pitched about the coupling 969 (shown in FIG. 6) in rotation direction 942. If the length 956 of the second strut 906 is increased, the support beam 902 can be pitched about the coupling 969 in rotation direction 940.

[0065] In some embodiments, the first strut 904 and the second strut 906 may include length adjustability. For example, as shown in FIG. 6, the first strut 904 may include a first portion 903a and a second portion 903b. In some embodiments, the first portion 903a may fit within the second portion 903b (e.g., the first portion 903a including a smaller outer diameter tube fitting within a larger inner diameter tube of a second portion 903b, the first portion 903a may telescope within the second portion 903b, etc.). The first strut 904 may be extendable and retractable by sliding the first portion 903a out of or into the second portion 903b, respectively. Further, for example, as shown in FIG. 6, the second strut 906 may include a first portion 905a and a second portion 905b. In some embodiments, the first portion 905a may fit within the second portion 905b (e.g., the first portion 905a including a smaller inner diameter tube fitting within a larger outer diameter tube of the second portion 905b, the first portion 905a may telescope within the second portion 905b, etc.). The second strut 906 may be extendable and retractable by sliding the first portion 905a out of or into the second portion 905b, respectively. As such, the height 930 and orientation of the interface frame 111 with respect to the base frame 125 may be manipulated by adjusting the length 954 of the first strut 904, the length 956 of the second strut 906, or a combination of the length 954 and length 956. Although first, second, third, fourth, etc. are used herein, these are simply used to identify similarly named elements and should not be considered limiting or to connote a sequence or order of importance.

Each adjustable length being adjustable through any suitable means to retain the pads in position when a user is exercising. However, in some embodiments, as described with regard to pin holes 438b, the lengths of the pads along the beams are adjustable, as shown, with a pin 438a or pin 450a mated to one or more pin holes 438b or pin holes 450b, respectively, that provide a predetermined selection of lengths along the beam 436 and beam 447, respectively. In some embodiments, the second beam 436 is adapted to include a second beam adapter 445 that adjusts the angle and orientation of the second beam based on utilization of the belt squat assembly 460. As shown in FIGS. 21A and 21B, the adapter 445 extends and changes the angle of the second beam 436 to relocate the pads 442a and 442b to allow greater access to the weight horn 456 and prevent the pads 442a and 442b from blocking access to placing of weights on the weight horn 456.

[0046] The foregoing is a summary, and thus, necessarily limited in detail. The above-mentioned aspects, as well as other aspects, features, and advantages of the present technology will now be described in connection with various embodiments. The inclusion of the following embodiments is not intended to limit the disclosure to these embodiments, but rather to enable any person skilled in the art to make and use the claimed subject matter. Other embodiments may be utilized, and modifications may be made without departing from the spirit or scope of the subject matter presented herein. Aspects of the disclosure, as described and illustrated herein, can be arranged, combined, modified, and designed in a variety of different formulations, all of which are explicitly contemplated and form part of this disclosure.

[0047] Generally, use of a multitude of exercise machines involves many inconveniences such as those related to space constraints, financial burdens placed on individuals, and / or difficulty with setup. However, because many people desire a diverse workout regimen to target different muscle groups and achieve well-rounded fitness, oftentimes, many machines are needed. For example, accommodating a range of machines for strength training, flexibility, and specialized exercises can quickly clutter one's home or gym space. Furthermore, owning multiple machines can be expensive, not to mention the maintenance costs and regular upgrades that may be required. The fragmentation created in exercise equipment can also deter some from staying committed to their fitness journey, as the logistical challenges and costs associated with acquiring and maintaining various machines can make consistent exercise more challenging. Multi-configuration exercise devices described herein are utilized to solve these issues of space, convenience, and financial constraints.

[0048] The technical problems to be solved by the exercise devices and / or assemblies described herein are floor space constraints and using a plurality of devices to execute a plurality of various exercises. In some embodiments, the exercise devices / assemblies described herein solve the above technical problems by saving floor space in a gym facility, home gym, living room, office, etc. where the exercise device may be used, while also providing a user with a plurality of configurations to perform various exercises on or using the exercise device. In some embodiments, the exercise device is transitionable between two configurations, more than two configurations, a plurality of configurations, three configurations, four configurations, five configurations, or six configurations. In some embodiments, any of the configurations may be used with or without one or more pads or a plurality of pads that are couplable to the interface frame. Further, additional removable assemblies may be included to expand on the number of exercises covered. In some embodiments, the multi-configuration exercise device may interface with a leg exercise assembly. In some embodiments, the leg exercise assembly may further include other removable assemblies to create additional configurations for further exercises (e.g., weighted hamstring curls, weighted quad exercises, belt squats, and / or cable adapters for weight systems.

[0049] Multi-configuration exercise devices described herein include an interface frame operatively coupled to a base frame. Multi-configuration exercise devices described herein include at least one hinged portion or point between the interface frame and base frame opposite an adapter site for a leg exercise assembly. For example, a leg exercise assembly may be reversibly couplable to a first end portion of an interface frame or a base frame, while the hinged portion may be on a second end portion of the interface or the base frame, opposite the first end portion. Said still another way, the leg exercise assembly may be on a first side of a latitudinal axis, and the hinged portion may be on a second side of the latitudinal axis, opposite the first side. For example, the interface frame may decline or incline, relative to the base frame, about the at least one hinged portion or point. Multi-configuration exercise devices contemplated herein include a variety of configurations with different interface frame heights and orientations, with respect to the base frame. Additionally, multi-configuration exercise devices described herein may include a multitude of configurations achieved by removing one or more pads or coupling one or more pads to the interface frame and / or the base frame. The various configurations of interface frame heights and orientations, with respect to the base frame, have been contemplated to be combined with any pad configuration. The contemplated configurations are intended for a multitude of exercises.

[0050] In accordance with 37 CFR 1.57, the entirety of International Patent Application PCT / US24 / 11560, filed Jan. 15, 2024, is hereby expressly incorporated by reference into this provisional patent application for all purposes. This incorporation is made to provide details pertinent to the understanding, operation, and implementation of inventions described and claimed herein, and to supplement the disclosure content of this application.

As such, tightening the threaded pin 152, when the slot bracket 126 is slipped onto the threaded pin 152, may at least partially couple the interface mechanism 114 of the leg exercise assembly 100 to the multi-configuration exercise device 120. As shown in FIGS. 8-11, a multi-configuration exercise device 120 may optionally include a first weight horn 150a and a second weight horn 150b coupled to the base frame 125. As shown in FIG. 13, a weight horn 150 (e.g., a first or second weight horn) may both include a post portion 156 and a stud portion 158. The post portion 156 may include a diameter 210 greater than the diameter 212 of the stud portion 158. The stud portion 158 may be threaded and may couple to the base frame 125 of the multi-configuration exercise device 120 by threading the stud portion 158 into a female thread portion (not shown) of the base frame 125. In some embodiments, as shown in FIG. 5, the interface mechanism 114 may include a tube 153. For example, the tube 153 may be a rectangular tube. The tube 153 (shown in FIG. 5) may define a first pair of holes near a first end 154 of the tube 153, including an upper hole 130 and a lower hole 132. As shown in FIG. 12, the upper hole 130 may include a diameter 202 greater than the diameter 200 of the lower hole 132. In some embodiments, the holes are concentric to one another with a shared center point. As shown in FIG. 5, the holes 132, 130 may have offset center points, however, the holes 130 must be able to retain at least a post portion of a weight horn 150a. The diameter 202 of the upper hole 130 may be greater than the diameter 210 of the post portion 156a of the first weight horn 150a. The diameter 200 of the lower hole 132 may be greater than the diameter 212 of the stud portion 158 of the first weight horn 150a but less than the diameter 210 of the post portion 156a of the first weight horn 150a. The tube 153 may define a second pair of holes near a second end 157 of the tube 153, including an upper hole 134 and a lower hole 136. As shown in FIG. 12, the upper hole 134 may include a diameter 202 greater than the diameter 200 of the lower hole 136. The diameter 202 of the upper hole 134 may be greater than the diameter of the post portion 156b of the second weight horn 150b. The diameter 200 of the lower hole 136 may be greater than the diameter 212 of the stud portion 158 of the second weight horn 150b but less than the diameter 210 of the post portion 156b of the second weight horn 150b. As such, the first weight horn 150a may be placed within the first pair of holes of the interface mechanism 114 and coupled to the base frame 125 of the multi-configuration exercise device 120, and the second weight horn 150b may be placed within the second pair of holes of the interface mechanism 114 and coupled to base frame 125 of the multi-configuration exercise device 120. The use of the first weight horn 150a and / or the second weight horn 150b may be used alone or in combination with the slot bracket 126 to removably couple the leg exercise assembly 100 to the multi-configuration exercise device 120. Although leg exercise assemblies are shown herein, any accessory (e.g., different types of straps or frame extending devices to provide resistance at different directions / angles, etc.)may use the interface mechanisms described herein to removably attach an accessory to an exercise device.

[0053] FIG. 10 shows a multi-configuration exercise device 120 without a leg exercise assembly 100 coupled to the device 120. FIGS. 3A, 3B, 8, and 9 illustrate the leg exercise assembly 100 coupled to the multi-configuration exercise device 120. The orientation and angle of the interface frame 111 (shown in FIG. 8) may be adjusted to interface (i.e., the adjustable interface frame) accordingly with the leg exercise assembly 100, for example, orienting the interface frame 111 in an incline and / or about horizontal or declined toward the ground to interface with the leg exercise assembly 100. A user may sit on the pads 123a, 123b (although two pads are shown, one pad may be used or more than two pads, for example, three pads may be used) on the end 127 (shown in FIGS. 9 and 10) of the multi-configuration exercise device 120, place their legs over the third set of pads 104a, 104b (i.e., positioning pads 104a, 104b underneath the user's knee) and place their legs under the first set of pads 106a, 106b (i.e., positioning pads 106a, 106b above or on top of the ankle of the user), such that the user may perform leg extensions with weight resistance based on the amount of weight added to the weight horn 116. Alternatively, the user may remove the semi-cylindrical pad 129 (shown in FIG. 9), lie face down on the multi-configuration exercise device 120, place their legs over the third set of pads 104a, 104b (i.e., positioning pads 104a, 104b above their knees, under their thighs), and place their legs under the second set of pads 102a, 102b, such that the user may perform leg curls with weight resistance based on the amount of weight added to the weight horn 116.

[0057] FIGS. 6 and 7 illustrate an embodiment of a multi-configuration exercise device 900 in an example configuration. The configuration shown in FIG. 6 may be used, for example, by a user to perform abdominal exercises (e.g., sit-ups), hamstring exercises (e.g., glute-ham development), and / or lower back exercises (e.g., 90-degree back extensions). The device 900 includes a base frame 125 and an interface frame 111 operatively coupled together. When the base frame 125 is laid upon a surface (e.g., the plane defined by the horizontal axis 996 and the normal axis 929), such that the longitudinal axis 960 of the base frame 125 is approximately parallel to the surface, and with gravity acting approximately normal to the surface, the base frame 125 rigidly supports and stabilizes the device 900. The base frame 125 may be operatively coupled to the interface frame 111 via a support beam 902. Support beam 902 may be hingedly coupled to the base frame 125 using coupling 969, and the support beam 902 may be hingedly coupled to the interface frame 111 using coupling 962. The support beam 902 may be further coupled to the interface frame 111 using a first strut 904. The first strut 104 may be hingedly coupled to the support beam 902 using coupling 966, and the first strut 104 may be hingedly coupled to the interface frame 111 using coupling 967. The support beam 902 may be further coupled to the base frame 125 using a second strut 906. The second strut 106 may be hingedly coupled to the support beam 902 using coupling 964, and the second strut 106 may be hingedly coupled to the base frame 125 using coupling 270. Couplings 967, 962, 964, 966, 969, 270 may allow rotation adjustment in rotation directions 940 and 942 (shown in FIG. 7). The interface frame 111 may optionally include a plurality of pads: pad 908, pad 910, cylindrical pad 914, and cylindrical pad 914. Additionally, the interface frame 111 may include one or more handles 924. The base frame 125 may optionally include one or more wheels 918 and one or more weight pegs 921. The height 930 (shown in FIG. 7) and orientation of the interface frame 111 may be manipulated with respect to the base frame 125.

[0058] FIG. 7 illustrates the multi-configuration exercise device 900 in an expanded configuration. For example, the height 930 of the device 900 shown in FIG. 7 may be about 0.75 m to about 1.25 m; about 0.80 m to about 1.20 m; about 0.90 m to about 1.10 m; etc. Orientation of the interface frame 111 is with respect to the base frame 125, which may be between the longitudinal axis 968 of the interface frame 111 and the longitudinal axis 960 of the base frame 125, or the absence thereof (i.e., if the longitudinal axis 968 of the interface frame 111 is approximately parallel to the longitudinal axis 960 of the base frame 125). For example, the interface frame 111 may be rotated with respect to a plane defined by the horizontal axis 996 and the vertical axis 994 in rotation direction 940, such that the interface frame 111 is in an incline. An incline exists when the second angle 934 (shown in FIG. 7) is greater than the first angle 933 and the degree value of incline is the differential between second angle 934 and the first angle 933. For example,

[0059] In some aspects, the techniques described herein relate to a leg exercise assembly, including: a first beam coupled to a second beam at an angle; a support column coupled to an interface mechanism and hingedly coupled to the first beam, wherein the interface mechanism is configured to removably couple the leg exercise assembly to a multi-configuration exercise device, wherein the multi-configuration exercise device includes at least one hinged portion between an interface frame and base frame, opposite the removable coupling to the interface mechanism; and a pair of leg pads on each of the first beam and the second beam.

[0060] In some aspects, the techniques described herein relate to an exercise device including: a leg exercise assembly including: a first beam coupled to a second beam at a first angle, a support column coupled to an interface mechanism and hingedly coupled to the first beam, wherein the interface mechanism is configured to removably couple to a multi-configuration exercise device, a first pair of pads coupled to the first beam, and a second pair of pads coupled to the second beam; and the multi-configuration exercise device removably coupled to the leg exercise assembly, the multi-configuration exercise device including: a base frame, an interface frame, and a hinge between the base frame and the interface frame, wherein the multi-configuration exercise device is adjustable about the hinge opposite the removable coupling to the interface.

[0061] In some aspects, the techniques described herein relate to an exercise device including: a leg exercise assembly including: a first beam coupled to a second beam at a first angle, a weight horn coupled to the first beam, a support column coupled to an interface mechanism and hingedly coupled to the first beam, wherein the interface mechanism is configured to removably couple to another exercise device, a first pair of pads coupled to the first beam, and a second pair of pads coupled to the second beam; and a multi-configuration exercise device removably coupled to the leg exercise assembly, the multi-configuration exercise device includes an adjustable interface frame.

[0062] In some aspects, the techniques described herein relate to an exercise device including: a leg exercise assembly including: a first beam, a weight horn, a support column coupled to an interface mechanism and hingedly coupled to the first beam, wherein the interface mechanism is configured to removably couple to a multi-configuration exercise device, and a first pair of pads coupled to the first beam; and the multi-configuration exercise device removably coupled to the leg exercise assembly, the multi-configuration exercise device includes an adjustable interface frame to couple to the interface mechanism.

[0063] In some aspects, the techniques described herein relate to a leg exercise assembly, including: a first beam; a weight horn coupled to the first beam; a support column coupled to an interface mechanism and hingedly coupled to the first beam, wherein the interface mechanism is configured to removably couple to a multi-configuration exercise device; and a first pair of pads coupled to the first beam.

[0064] In some aspects, the techniques described herein relate to a leg exercise assembly, including: a first beam; a support column coupled to an interface mechanism and hingedly coupled to the first beam, wherein the interface mechanism is configured to removably couple to a multi-configuration exercise device that is declinable and inclinable about a hinge portion opposite the interface mechanism; and a first pair of pads coupled to the first beam. When the second angle 934 is about 45 degrees and the first angle 933 is about 20 degrees, the resulting incline is about 25 degrees. The interface frame 111 incline may be greater than about 0 degrees (i.e., the longitudinal axis 968 of the interface frame 111 being approximately parallel to the longitudinal axis 960 of the base frame 125) to about 90 degrees; greater than about 0 degrees to about 60 degrees; greater than about 0 degrees to about 45 degrees; etc. Inversely, the interface frame 111 may be rotated with respect to a plane defined by the horizontal axis 996 and the vertical axis 994 in rotation direction 942, such that interface frame 111 decline is created. Decline exists when the second angle 934 (shown in FIG. 7) is less than the first angle 934 and the degree value of decline is the differential between second angle 934 and the first angle 933. For example, when the second angle 934 is about 20 degrees and the first angle 933 is about 45 degrees, the resulting decline 25 degrees. Decline may be greater than about 0 degrees (i.e., the longitudinal axis 968 of the interface frame 111 being approximately parallel to the longitudinal axis 960 of the base frame 125) to about 90 degrees; greater than about 0 degrees to about 60 degrees; greater than about 0 degrees to about 45 degrees; etc. If the length 954 of the first strut 904 is reduced, the third angle 970 between the first strut 904 and the interface frame 111 is increased, while the first angle 933 between the interface frame 111 and the support beam 902 is decreased. Inversely, if the length 954 of the first strut 904 is increased, the third angle 970 between the first strut 904 and the interface frame 111 is decreased, while the first angle 933 between the interface frame 111 and the support beam 902 is increased. If the length 956 of the second strut 906 is reduced, the fourth angle 936 between the second strut 906 and the base frame 125 is decreased, and the second angle 934 between the base frame 125 and the support beam 902 is decreased. Inversely, if the length 956 of the second strut 906 is increased, the fourth angle 936 between the second strut 906 and the base frame 125 is increased, and the second angle 934 between the base frame 125 and the support beam 902 is increased. Additionally, if the length 954 of the first strut 904 is reduced, the interface frame 111 can be pitched about the coupling 962 (shown in FIG. 6) in rotation direction 940. If the length 954 of the first strut 904 is increased, the interface frame 111 can be pitched with respect to a plane defined by the horizontal axis 996 and the vertical axis 994 about the coupling 962 (shown in FIG. 6) in rotation direction 942. Additionally, if the length 956 of the second strut 906 is reduced, the support beam 902 can be pitched about the coupling 969 (shown in FIG. 6) in rotation direction 942. If the length 956 of the second strut 906 is increased, the support beam 902 can be pitched about the coupling 969 in rotation direction 940.

[0065] In some embodiments, the first strut 904 and the second strut 906 may include length adjustability. For example, as shown in FIG. 6, the first strut 904 may include a first portion 903a and a second portion 903b. In some embodiments, the first portion 903a may fit within the second portion 903b (e.g., the first portion 903a including a smaller outer diameter tube fitting within a larger inner diameter tube of a second portion 903b, the first portion 903a may telescope within the second portion 903b, etc.). The first strut 904 may be extendable and retractable by sliding the first portion 903a out of or into the second portion 903b, respectively. Further, for example, as shown in FIG. 6, the second strut 906 may include a first portion 905a and a second portion 905b. In some embodiments, the first portion 905a may fit within the second portion 905b (e.g., the first portion 905a including a smaller inner diameter tube fitting within a larger outer diameter tube of the second portion 905b, the first portion 905a may telescope within the second portion 905b, etc.). The second strut 906 may be extendable and retractable by sliding the first portion 905a out of or into the second portion 905b, respectively. As such, the height 930 and orientation of the interface frame 111 with respect to the base frame 125 may be manipulated by adjusting the length 954 of the first strut 904, the length 956 of the second strut 906, or a combination of the length 954 and length 956. Although first, second, third, fourth, etc. are used herein, these are simply used to identify similarly named elements and should not be considered limiting or to connote a sequence or order of importance.

[0066] FIG. 3A illustrates a leg exercise assembly 100 including a removable second beam 108 and second pair of pads 102a,102b. The second beam 108 may include a post 109 rigidly coupled to the first beam 112 and the post 109 may define a hole (not shown). The second beam 108 may include a sleeve 107 defining an inner diameter sized and / or shaped to slide over the post 109. The sleeve 107 may define a hole 113 that may be aligned with the hole defined by the post 109 such that a pin 142 may slide through the aligned holes, locking the sleeve 107 onto the post 109. For proper pin insertion and removal, lash between the pin and hole may facilitate insertion and removal. It may be advantageous to include a mechanism for the removal of lash between pin 142 and the holes of the post 109 and the sleeve 107. As shown in FIG. 15, the sleeve 107 may include a threaded pin 342 threaded in the sleeve 107 approximately perpendicular to the pin 142. As such, threaded pin 342 may be tightened to press against the post 109 to remove lash between pin 142 and the holes of the post 109 and the sleeve 107.
