Description

[0001] Cross - Reference to Related Applications

[0002] This application is a continuation of a portion of U.S. application Ser. No. 18 / 466,926, filed Sep. 14, 2023. The entire disclosure of the above application is incorporated herein by reference. Technical Field

[0003] The present technology relates to an electric fitness device, and more particularly, to an electric resistance exercise device. Background Art

[0004] This section provides background information related to the present disclosure, which is not necessarily prior art.

[0005] Resistance exercise devices (also known as strength training equipment) are essential tools for enhancing muscle strength, endurance, and overall fitness. These devices work by providing resistance to muscle contractions, challenging the muscles' adaptability and growing stronger over time. Resistance exercise is a key component of a comprehensive fitness program and offers many benefits, including increased bone density, improved metabolism, and enhanced physical performance.

[0006] Resistance exercise devices come in different forms, including resistance bands, kettlebells, exercise balls, suspension trainers, and more. Each device offers unique benefits and can be used for specific exercises or as part of a comprehensive workout program. Whether in a gym or a home setting, incorporating these devices into a fitness routine can significantly improve strength, muscle tone, and overall physical health. As with any exercise program, it is important to use proper form and technique when using resistance exercise devices to maximize benefits and minimize the risk of injury.

[0007] One of the most common types of resistance exercise devices is free weights, such as dumbbells and barbells. The versatility of free weights allows for a wide range of exercises targeting different muscle groups. Dumbbells are hand - held weightlifting devices of various sizes, making them suitable for people of all fitness levels. On the other hand, a barbell consists of a long bar with weight plates on each end and is often used for compound exercises such as squats and deadlifts.

[0008] Resistance exercise machines are another popular type of device commonly found in home gyms and fitness centers. These machines use a system of cables, pulleys, and weight stacks to provide resistance during exercise. Motors and gearboxes can also be used to provide resistance, replacing the weight stacks. The advantage of resistance machines is that they provide controlled movement and can be safer for beginners or individuals recovering from injuries. They also allow for the isolation of specific muscles.

[0009] In recent years, resistance exercise devices have seen innovation incorporating technology and data-tracking features. Smart resistance machines often come with built-in screens or are connected to fitness applications, providing users with real-time feedback, workout guidance, and performance metrics. This integration of technology has made resistance training more engaging and personalized, meeting the needs of individuals with different fitness goals. However, current electric resistance exercise equipment may lack sufficient resistance to generate effective electric resistance for workouts. Additionally, the spool mechanisms of current devices may cause the resistance cord to become tangled during use.

[0010] Accordingly, there is a need for an electric resistance exercise device with a high level of resistance and an organized cord mechanism. Summary of the Invention

[0011] In accordance with the present disclosure, a fitness device has been unexpectedly discovered that includes a resistance exercise device having a high level of resistance and an organized cord mechanism.

[0012] The present technology provides a fitness device for use by a user. The fitness device may include a resistance assembly that includes a spool, a motor, a gearbox, a pulley system, and a cord. The spool may include a first end and a second end. The motor may be selectively engaged with the spool and may be arranged adjacent to the first end of the spool. The motor may be configured to generate resistance. The gearbox may be disposed between the motor and the spool. The pulley system may be arranged adjacent to the second end of the spool. The cord may be disposed on the spool and the pulley system and may be configured to wind and unwind in a single layer on the spool when pulled by the user. The pulley system may include a first pulley and a ball-and-socket joint. The first pulley may be arranged adjacent to the spool and may be configured to receive the cord. The ball-and-socket joint may include an opening therethrough. The opening may be configured to receive the cord.

[0013] The present disclosure also provides a method of using a fitness device by a user. The fitness device of the present disclosure may be provided. The fitness device may be positioned in a desired location and orientation for the user to exercise. The fitness device may be secured in a selected position. Workout settings may be adjusted on the fitness device. The user may selectively engage the cord and begin exercising.

[0040] The following description of the technology is merely exemplary in nature with respect to the subject matter, manufacture, and uses of one or more inventions and is not intended to limit the scope, application, or use of any particular invention claimed in this application or in such other applications as may claim the benefit of priority of this application, or in patents published therefrom. With respect to the disclosed methods, unless otherwise expressly stated, the order of the presented steps is exemplary in nature and, accordingly, the order of the steps may be different in various embodiments, including where particular steps may be performed simultaneously. As used herein, "a" and "an" denote the presence of "at least one" item; when possible, there may be multiple such items. Unless otherwise expressly indicated, all numerical quantities in this specification should be understood to be modified by the word "about" and all geometric and spatial descriptors should be understood to be modified by the word "substantially" to describe the broadest scope of the technology. When applied to a numerical value, "about" means some slight imprecision in the calculated or measured value (some proximity to the exact value; approximately or reasonably close to the value; nearly). If, for some reason, the imprecision provided by "about" and / or "substantially" is not understood in the ordinary sense in the art, then "about" and / or "substantially" as used herein at least indicates variations that may be caused by the ordinary methods of measuring or using such parameters.

[0041] Although the open-ended term "comprising", as a synonym for non-limiting terms such as "including", "containing", or "having", is used herein to describe and claim embodiments of the present technology, embodiments may alternatively be described using more restrictive terms such as "consisting of" or "consisting essentially of". Thus, for any given embodiment that recites materials, components, or process steps, the present technology also specifically includes embodiments consisting of or consisting essentially of such materials, components, or process steps, which exclude additional materials, components, or processes (for "consisting of") and exclude additional materials, components, or processes that affect the distinguishing characteristics of the embodiment (for "consisting essentially of"), even if such additional materials, components, or processes are not explicitly recited in the present application. For example, a recitation of a composition or method containing elements A, B, and C specifically contemplates embodiments consisting of or consisting essentially of: A, B, and C, excluding element D that may be recited in the art, even if element D is not explicitly described as being excluded herein.

[0042] Unless otherwise stated, the disclosure of a range includes the endpoints and includes all different values and further divided ranges within the entire range. Thus, for example, a range of "from A to B" or "from about A to about B" includes A and B. The disclosure of specific values and value ranges for particular parameters (such as amounts, weight percentages, etc.) does not exclude other values and value ranges useful herein. It is contemplated that two or more specific example values for a given parameter may define the endpoints of a range of values that may be claimed for the parameter. For example, if parameter X is exemplified herein as having value A and is also exemplified as having value Z, then it is contemplated that parameter X may have a range of values from about A to about Z. Similarly, it is contemplated that the disclosure of two or more ranges for a parameter's value (whether such ranges are nested, overlapping, or distinct) encompasses all possible combinations of ranges of values that may be claimed using the endpoints of the disclosed ranges. For example, if parameter X is exemplified herein as having values within the ranges of 1 to 10, or 2 to 9, or 3 to 8, it is also contemplated that parameter X may have other value ranges, including 1 to 9, 1 to 8, 1 to 3, 1 to 2, 2 to 10, 2 to 8, 2 to 3, 3 to 10, 3 to 9, etc.

[0043] When referring to an element or layer “on,” “joined to,” “connected to,” or “coupled to” another element or layer, it can be directly on, joined, connected, or coupled to the other element or layer, or intervening elements or layers may be present. In contrast, when an element is referred to as being “directly on,” “directly joined to,” “directly connected to,” or “directly coupled to” another element or layer, there may be no intervening elements or layers. Other words used to describe the relationship between elements should be interpreted in a like manner (e.g., “between” versus “directly between,” “adjacent” versus “directly adjacent,” etc.). As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items.

[0044] Although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, layers, and / or sections, these elements, components, regions, layers, and / or sections should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or section from another. Terms such as “first,” “second,” and other numerical terms when used herein do not imply a sequence or order unless the context clearly indicates. Thus, a first element, first component, first region, first layer, or first section discussed below may be termed a second element, second component, second region, second layer, or second section without departing from the teachings of the exemplary embodiments.

[0045] For ease of description, spatially relative terms such as “inner,” “outer,” “beneath,” “below,” “lower,” “above,” “upper,” etc. may be used herein to describe the relationship of one element or feature to another element or feature as shown in the figures. Spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, an element described as “beneath” or “below” other elements or features would then be oriented “above” the other elements or features. Thus, the exemplary term “beneath” can include both an orientation of above and below. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

[0046] The present disclosure provides a fitness device 100 for use by a user, the fitness device including a resistance assembly 102, in Figures 1 to 17is generally shown. The resistance assembly 102 can include a spool 104, a motor 106, a gearbox 108, a pulley system 110, and a cord 112. Advantageously, the shape of the spool 104 included in the resistance assembly 102 can prevent the cord 112 from tangling on the spool 104 during unwinding and winding, and thus provide a more effective workout for the user. Additionally, the fitness device 100 can provide a high level of resistance to the user in a compact and lightweight fitness device.

[0047] As Figures 11A to 11B shown, the shape of the spool 104 can be frustoconical, such that the spool 104 has a first end 114 and a second end 116. The cord 112 can be coupled to the spool 104 at the first end 114. The diameter D1 of the first end 114 can be smaller than the diameter D2 of the second end 116. This feature can allow the cord 112 to wind around the spool in an orderly, neat, and efficient manner, thus allowing the user to have a more productive workout. Advantageously, the frustoconical nature of the spool 104 facilitates the self-alignment of the cord 112 on the spool 104 during rewinding without tangling. Desirably, the spool 104 allows the user to experience a smooth pull of the cord 112 compared to pulling a non-uniformly wound cord 112, which would create an unsteady feeling during the workout. Additionally, the frustoconical shape prevents the cord 112 from becoming tangled and jammed when pulled by the user. In a particular embodiment, the cord 112 can be wound around the spool 104 in a single layer to prevent the cord from collapsing on the spool 104, which would result in an unsteady and uneven pull of the cord 112 during operation.

[0048] Referring Figures 12A to 12C to, the spool 104 can include a ridge 115. The ridge 115 can prevent the cord 112 from winding onto the spool 104 in a direction opposite to the first end 114. In the operation of winding the cord 112 onto the spool 104, and as Figure 12A shown, the cord 112 can begin to wind around the spool 104 in a single layer, from the second end 116 to the first end 114, forming a cord bundle 113. Referring Figure 12B to, as the cord 112 continues to wind around the spool 104, the cord bundle 113 is pushed from the second end 116 to the first end 114 until the cord bundle 113 occupies the entire length of the spool 104, as Figure 12C shown.

[0049] The spool 104 can be formed of a solid material. The solid material can allow the spool 104 to be stable and durable when rotating to unwind and rewind the cord 112. As a non-limiting example, the spool 104 can be formed of various polyolefins and their mixtures, polypropylene, high-density polyethylene (HDPE), and / or polyethylene terephthalate (PET). Alternatively, as an example, the spool 104 can be formed of metal, wood, or ceramic. Those of ordinary skill in the art can select other suitable materials within the scope of the present disclosure to form the spool 104.

[0050] Reference Figure 8 , the motor 106 can be selectively engaged with the spool 104 and configured to generate resistance. The motor 106 can be disposed adjacent to the first end 114 of the spool 104 and configured to rotate the spool 104 in a forward or reverse direction depending on whether the cord 112 is being wound or unwound on the spool 104. In a particular embodiment, the transmission 108 can be an intermediate member between the motor 106 and the spool 104. The motor 106 can provide variable torque to the spool 104 and in this way provide the resistance required by the user to use the fitness device 100. When the user adjusts the resistance, the motor 106 can provide an instantaneous adjustment of the torque. When the user stops pulling the cord 112, the motor 106 can also wind the cord 112 onto the spool 104. As a non-limiting example, the motor 106 can include a brushless DC (BLDC) motor. It should be further understood that those skilled in the art can use different motors 106 as needed.

[0051] The transmission 108 can be disposed between the motor 106 and the spool 104. The transmission 108 can be configured to increase the torque output of the motor 106. The spool 104 can be connected to the input end 118 of the transmission 108. As a non-limiting example, a one-way bearing can be used to connect the spool 104 and the transmission 108, and the one-way bearing is configured to transmit torque from the spool 104 to the transmission 108 in a first direction when the user pulls the cord 112. When the cord 112 is rewound, the one-way bearing can prevent the transmission 108 from rotating in a second direction opposite to the first direction.

[0052] The transmission 108 can be any suitable transmission 108 as determined by those skilled in the art. In a particular embodiment, a multi-stage planetary transmission 108 with helical gears can be used to optimally transmit force. In a particular more specific embodiment, the transmission 108 can be configured to achieve a gear ratio. It should be understood that within the scope of the present disclosure, those skilled in the art can scale the transmission gear ratio higher or lower. It should be further understood that those skilled in the art can use different techniques for the transmission 108 as needed.

[0053] As Figure 8As shown, the pulley system 110 can be arranged adjacent to the second end 116 of the spool 104. The pulley system 110 guides the cord 112 from the spool 104 out of the resistance assembly 102. The pulley system 110 can include a first pulley 120 and a second pulley 122, both of which are configured to receive the cord 112. Additionally, one or more pulley mounting elements 128 can be used to secure the first pulley 120 and the second pulley 122 within the resistance assembly 102 and prevent the cord 112 from becoming misaligned or skewed as it winds and unwinds around the spool 104. The first pulley 120 can be arranged adjacent to the spool 104 such that when the cord 112 moves from the first pulley 120 to the spool 104 or vice versa, the cord 112 remains within a plane perpendicular to the length of the spool 104. In this way, as the cord 112 moves between the first pulley 120 and the spool 104, the cord remains straight and is not positioned at an angle. Advantageously, this can allow for a smooth transition of the cord 112 between the first pulley 120 and the spool 104 and facilitate the cord 112 to wind and unwind in a single layer around the spool 104. The cover 130 can be integral with or permanently or removably connected to one or more pulley mounting elements 128. The top 132 of the cover 130 can guide the cord 112 through the exit port 134 of the pulley system 110 and the resistance assembly 102 for use by the user. It should be noted that the cover 130 and the exit port 134 can allow the cord to rotate 360° as the cord exits and enters the exit port 134. Advantageously, this reduces the overall friction experienced by the cord during exercise.

[0054] It should be understood that any number and orientation of pulleys can be employed, as determined by one of ordinary skill in the art. As a non-limiting example, straight pulleys and angled pulleys can be arranged in the resistance assembly 102 and used in concert to properly align the cord 112 relative to the spool 104 and the exit port 134 during various exercise regimens.

[0055] The cord 112 can be arranged on the spool 104 and passed through the pulley system 110. When pulled by the user, the cord 112 can be unwound as Figure 11A shown and wound around the spool 104 as Figure 11B shown. The cord 112 can be made of any flexible, durable material or combination of materials. Desirably, the cord 112 can be made of a strong, lightweight material. One of ordinary skill in the art can determine any suitable length, diameter, and material for the cord. The cord 112 can also include an attachment device 136. The attachment device 136 can be provided at the end of the cord 112. As a non-limiting example, the attachment device 136 can be a loop 138, as shown in the figure. The loop 138 can be adapted to receive a locking carabiner, snap hook, or any other suitable connecting element provided on a handle or any other desired accessory.

[0056] Reference Figure 10 , a pair of handles 140 may be coupled to the attachment device 136 of the cord 112 to allow a user to use the fitness device 100. Each of the pair of handles 140 may be ergonomically shaped to fit the user's hand. In operation, the user may grip the pair of handles 140, pull the pair of handles 140 upward against resistance and release the tension on the cord 112 and the pair of handles 140 to wind the cord 112 onto the spool 104 to use the fitness device 100.

[0057] As Figure 7 shown, the resistance assembly 102 may include a battery 142 disposed adjacent to the motor 106. Additionally, the battery 142 may be rechargeable and may be charged by the user by using the fitness device 100. The battery 142 may be used to provide power to the electronic components of the fitness device 100. It should be understood that other power sources may also be utilized within the scope of the present disclosure. The resistance assembly 102 may also include a fan 144, as Figure 8 shown, for cooling the motor 106 during use. The fitness device 100 may also include a built-in speaker 145, as Figure 4 shown, which may play music selected by the user. For example, the user may utilize Bluetooth to connect the fitness device 100 to receive media such as music or podcasts.

[0058] As Figure 1 shown, the fitness device 100 may include another resistance assembly 102'. As described above, the another resistance assembly 102' may include a spool 104', a motor 106', a gearbox 108', a pulley system 110', and a cord 112', as Figure 9 shown. The another resistance assembly 102' may operate similarly to the resistance assembly 102. Advantageously, in a particular embodiment of the fitness device 100 having the resistance assembly 102 and the another resistance assembly 102', the fitness device 100 may also include an execution unit 146, which communicates with both the resistance assembly 102 and the another resistance assembly 102' and is shown in Figures 1 to 5 . The execution unit 146 may convey to the user an exercise setting using any resistance scale, which may be displayed to the user on the display 148 and monitor the exercise setting.

[0059] The actuating unit 146 can be disposed between the resistance assembly 102 and another resistance assembly 102' such that a user can place one foot between the resistance assembly 102 and the actuating unit 146 and the other foot between the actuating unit 146 and the another resistance assembly 102' during operation. The actuating unit 146 is positioned centrally between the resistance assembly 102 and the another resistance assembly 102' such that the resistance assembly 102 and the another resistance assembly 102' extend out in opposite directions from each other. To this end, each of the resistance assembly 102 and the another resistance assembly 102' can be positioned under each arm on either side of the user's body during use.

[0060] Each of the resistance assembly 102 and the another resistance assembly 102' can be integrated with the actuating unit 146 or can be permanently or removably connected to the actuating unit 146. In a particular embodiment, each of the resistance assembly 102 and the another resistance assembly 102' can be configured to rotate relative to the actuating unit 146 between a use position and a storage position, as Figure 1 and Figure 10 shown. In the use position, the resistance assembly 102 and the another resistance assembly 102' extend outwardly in opposite directions from the actuating unit 146, and in the storage position, the resistance assembly 102 and the another resistance assembly 102' are positioned adjacent to each other and extend side by side away from the actuating unit 146. As a non-limiting example, any suitable connection mechanism (such as a torque hinge or a friction hinge) can be used to rotatably connect each of the resistance assembly 102 and the another resistance assembly 102' to the actuating unit 146.

[0061] In a particular more specific embodiment, each of the resistance assembly 102 and the another resistance assembly 102' can be coupled to the actuating unit 146 by a foot pedal 150, as Figure 1 shown. The foot pedal 150 can be permanently or removably connected to the actuating unit 146, the resistance assembly 102, and / or the another resistance assembly 102'. As will be determined by those skilled in the art, the foot pedal 150 can be made of any suitable material or combination of materials. As a non-limiting example, the foot pedal 150 can be manufactured using plastic, metal, or polycarbonate. The foot pedal 150 can include materials and / or surface textures that provide friction to stabilize the user when the fitness device 100 is in use.

[0062] In certain more specific embodiments, a mounting device (not shown) may be integrally formed with or permanently or removably connected to one or more of the actuator unit 146, the resistance assembly 102, and another resistance assembly 102'. As a non-limiting example, the mounting device may include clamps, straps, and mounting screws. The mounting device may be configured to removably or permanently secure the fitness device 100 in any desired orientation to any surface or object. Those skilled in the art may use any suitable mounting device as needed. In this way, the mounting device may allow the fitness device 100 to be mounted to various horizontal, vertical, and inclined surfaces to change the movement angle and / or direction of the cord 112 relative to the user's position.

[0063] The actuator unit 146, the resistance assembly 102, and / or another resistance assembly 102' may be made of wood, metal, plastic, and / or composite materials. However, it should be understood that those skilled in the art may employ different materials to configure the actuator unit 146, the resistance assembly 102, and / or another resistance assembly 102' as needed.

[0064] Continuing to refer Figure 13 and Figure 15 , the actuator unit 146 may include a nudge dial 152 configured to run or modify an exercise setting of the resistance assembly 102 specified by the user. It should be understood that in certain embodiments, the nudge dial 152 may be used to adjust the exercise setting of the resistance assembly 102, such as increasing or decreasing the resistance.

[0065] Alternatively, and referring Figure 16 , the actuator unit 146 may include a voice capture module 154 configured to run or modify an exercise setting of the resistance assembly 102 specified by the user. The fitness device 100 may also include a microphone (not shown) configured to enable the voice capture module 154. It should be understood that in certain embodiments, the voice capture module 154 may be used to adjust the exercise setting of the resistance assembly 102, such as increasing or decreasing the resistance.

[0066] In certain embodiments, and referring Figure 17 , the fitness device 100 may include a programmable device 156 configured to wirelessly communicate (e.g., short-range wireless Bluetooth, Internet or cloud-based communication, cellular network, etc.) with the resistance assembly 102 and / or the actuator unit 146. The programmable device 156 may include a processor and a non-transitory computer-readable medium. The non-transitory computer-readable medium may include instructions configured to allow a user to remotely run or modify an exercise setting of the resistance assembly 102 specified by the user. It should be understood that in certain embodiments, the programmable device 156 may be configured to directly operate on the resistance assembly 102 to modify the exercise setting without relaying the modification to the actuator unit 146.

[0067] The programmable device 156 can be further configured to provide a graphical user interface 158 feature that is configured to automatically adjust the position of the nudge dial 152 disposed on the actuator unit 146 according to a manual manipulation of the graphical user interface 158 feature provided by the user. For example, the user can move a slider on the graphical user interface 158 of a software application, thereby rotating the nudge dial 152 to increase or decrease the resistance of the fitness device 100. As needed, other types of graphical user interface 158 features for adjusting the position of the nudge dial 152 can also be used.

[0068] In operation, the user places the fitness device 100 on the floor and stands on one foot between the resistance assembly 102 and the actuator unit 146 while standing on the other foot between the actuator unit 146 and another resistance assembly 102'. The user's body weight can keep the fitness device 100 stable. The pair of handles 140 can be attached to the attachment devices 136, one handle being on the attachment device 136 of the resistance assembly 102 and the other handle being on the second attachment device 136' of the other resistance assembly 102'. The user pulls the cord 112 by means of the pair of handles 140. The cord 112 can provide the resistance supplied by the motor 106 when the user pulls it. As described above, the amount of resistance can be controlled by the actuator unit selected by the user.

[0069] Internally, the spool 104 is connected to the motor 106 via a gearbox 108. The motor 106 provides variable torque to the spool 104. The separate motor 106, gearbox 108, and spool 104 allow the user to seamlessly switch from exercising with one handle to exercising with two handles as needed. As described above, the torque can be adjusted immediately to any value. For example, there can be a force when pulling, but a very small force when the cord 112 is wound back, a very small force when the user pulls, but a large force on the way down, or a reduction in the counterweight when the cord 112 is pulled up. When the user pulls on the cord 112, the spool 104 rotates against the resistance provided by the motor 106 and unwinds the cord 112. When the user stops pulling the cord 112, the motor 106 winds the cord 112 back onto the spool 104.

[0070] The present disclosure also provides a method 200 for a user to use a fitness device, as Figure 18As shown. In step 202, the fitness device 100 of the present disclosure as described above can be provided. In step 204, the fitness device 100 can be positioned at a desired position and orientation for the user to exercise. In step 206, the fitness device 100 can be fixed in the selected position. In step 208, the exercise settings on the fitness device can be adjusted. As described above, the fitness device 100 can further include a nudge dial 152 configured to run or modify the exercise settings of the resistance component 102 specified by the user. Optionally, the fitness device 100 can include a voice capture module 154 configured to run or modify the exercise settings of the resistance component 102 specified by the user. In yet another embodiment, the fitness device 100 can include a programmable device 156 configured to communicate wirelessly with the resistance component 102. The programmable device 156 can include a processor and a non-transitory computer-readable medium. The non-transitory computer-readable medium can include instructions configured to allow the user to remotely run or modify the exercise settings of the resistance component specified by the user. In step 210, the user can selectively engage the cord 112 and start exercising. In step 212, the user can move the cord such that the cord is either wound or unwound on the spool.

[0071] Advantageously, the user can adjust the position and orientation of the fitness device 100, as well as any settings related to resistance, audio, visual, tracking, or any other customizable features, to achieve a full-body workout. The fitness device 100 is lightweight and compact both in use and in the storage position, making it easy to use, set up, transport, and store. According to a particular embodiment, the weight of the fitness device 100 can be less than ten (10) pounds. It should be understood that the user's body weight alone can be used to fix the fitness device 100 in place, allowing the user to operate the fitness device without any setup or additional equipment and in any position large enough to fit the user. It should be further understood that the fitness device 100 can also be fixed to any surface using mounting equipment or the weight from an object as needed. Advantageously, as a non-limiting example, mounting equipment can be used to attach the fitness device 100 to walls, doors, and benches. Ideally, this can allow the user to perform an exercise program with the fitness device 100 in an elevated or other unconventional position or location.

[0072] The fitness device 100 can be portable and adaptable and can be used indoors, outdoors, at home, at work, while traveling, and as needed. Using the fitness device 100 in various positions and orientations allows the user to exercise various muscle groups in various different ways. Similarly, combining the fitness device 100 with various accessories and various training applications allows the user to create customized, creative, and fun exercise programs.

[0073] Advantageously, the fitness device 100 is useful for any fitness level (beginner to expert). Beginner users can select zero resistance or a low level of resistance while using the fitness device 100. Expert users can increase the resistance over time as needed. The user avoids purchasing additional equipment (such as free weights) during use of the fitness device 100 and adding and removing additional equipment. In a more specific particular embodiment, the fitness device 100 can provide up to or more than thirty-five kilograms of resistance.

[0074] In Figure 19 and Figure 20 In another embodiment shown, the pulley system 110 can be arranged adjacent to the second end 116 of the spool 104. The pulley system 110 guides the cord 112 from the spool 104 out of the resistance assembly 102. The pulley system 110 can include a first pulley 120 and a ball joint 160. The first pulley 120 can be arranged adjacent to the spool 104 and can be configured to receive the cord 112. The first pulley 120 can be arranged adjacent to the spool 104 such that when the cord 112 moves from the first pulley 120 to the spool 104 or from the spool 104 to the first pulley 120, the cord 112 remains in a plane perpendicular to the length of the spool 104. In this way, the cord 112 remains straight as it moves between the first pulley 120 and the spool 104 and is not positioned at an angle. Advantageously, this can allow for a smooth transition of the cord 112 between the first pulley 120 and the spool 104 and facilitate single-layer winding and unwinding of the cord 112 on the spool 104. Return reference Figure 8 , a single mounting element 128 can be used to secure the first pulley 120 and the ball joint 160 within the resistance assembly 102 and can prevent the cord 112 from becoming misaligned or skewed as it winds and unwinds on the spool 104. Alternatively and as Figure 20 shown in, a plurality of mounting elements 128 can be used to mount the pulley system and the spool. The mounting elements 128 can also move within the resistance assembly 102, thereby allowing the user to rotate the cord 112 more during exercise, as Figure 19 shown. The ball joint 160 can include an opening 165 therethrough. The opening 165 can be configured to receive the cord 112. The ball joint 160 can allow the cord 112 to rotate in all directions. The pivot cap 164 can be integral with or permanently or removably connected to one or more of the pulley mounting element 128 or the ball joint 162, as Figure 20As shown, the pivot cap may include a hole 166 therethrough for receiving the cord 112. The pivot cap 164 may guide the cord 112 through the exit port 134 of the pulley system 110 and the resistance assembly 102 for use by the user. It should be noted that the pivot cap 164 and the exit port 134 may allow the cord 112 to rotate more greatly as it exits and enters the exit port 134. Advantageously, this reduces the overall friction experienced by the cord 112 during exercise.

[0075] Alternatively, and as Figures 22 to 23 shown, the fitness device 100 may include a funnel member 168 instead of the pulley system 110. The funnel member 168 may be disposed on the second end 116 of the spool 104 and may act as a support for the spool 104, as Figure 22 shown. The funnel member 168 may include a funnel 170 disposed at the upper portion of the funnel member 168. The funnel 170 may be shaped as an inverted funnel having a lip 172 at the base 174. The lip 172 of the funnel 170 may guide the cord 112 as it exits the funnel member 168. The funnel 170 may provide a small and predictable area of contact with the cord 112 and thereby reduce the friction felt by the cord 112 as it moves into and out of the funnel member 168 and into and out of the spool 104 during operation of the fitness device 100.

[0076] It should be understood that the funnel member 168 may be formed of a rigid material. As a non-limiting example, the funnel member 168 may be formed of plastic. As a preferred example, the funnel member 168 may be formed of metal to act as an additional support for the spool 104 and to increase the durability of the funnel member 168. Those skilled in the art may select an appropriate rigid material within the scope of the present disclosure.

[0077] As described above, the cap 130 may be integral with or permanently or removably connected to one or more of these pulley mounting elements 128. The top section 132 of the cap 130 may guide the cord 112 through the exit port 134 of the resistance assembly 102 for use by the user. It should be noted that the cap 130 and the exit port 134 may allow the cord to rotate 60° as it exits and enters the exit port 134. Advantageously, this reduces the overall friction experienced by the cord during exercise.

[0078] Continuing to refer to Figures 22 to 23, the spool 104 can be of a cylindrical shape such that the spool 104 has a first end 114 and a second end 116. The cord 112 can be coupled to the spool 104 at the first end 114. The first end 114, the second end 116, and the portion of the spool 104 disposed between the first end 114 and the second end 116 can be substantially the same in diameter. This feature can allow the cord 112 to be wound around the spool in an orderly, neat, and efficient manner, thereby allowing the user to have a more productive workout and can allow the cord 112 to be wound in multiple layers on the spool 104. Desirably, the spool 104 allows the user to experience a smooth pull of the cord 112 compared to pulling an unevenly wound cord 112, which would create a jerky feeling during the workout.
