Description

Technical Field

[0001] This utility model relates to a training device, specifically a training device for simulating isometric motion. Background Technology

[0002] Most existing training equipment requires users to lift heavy objects. However, lifting heavy objects puts pressure on the upper or lower limbs against gravity, potentially causing injury. Isometric exercises, on the other hand, involve muscles that maintain their length during contraction without joint movement. This type of exercise primarily works by increasing muscle tension to counteract fixed resistance; the muscle contracts without shortening its fibers, thus increasing muscle tension without changing its length. Given the characteristics of isometric exercises, training equipment can be designed to significantly reduce the risk of injury to the user's upper or lower limbs. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a training device that simulates isometric motion. When using this training device, the user can always control the force applied and the force that needs to be borne by their own body, so as to avoid potential injury to their own body.

[0004] The purpose of this utility model is achieved as follows:

[0005] A training device for simulating isometric motion, comprising,

[0006] Equipment base;

[0007] The upper limb training mechanism includes an upper limb training frame, a handrail assembly, and a first force sensor for collecting force data. The upper limb training frame is mounted on a base, the handrail assembly is movably connected to the upper limb training frame, the detection end of the first force sensor is connected to the handrail assembly, and the data output end of the first force sensor is communicatively connected to a data analysis and processing module. When a user performs upper limb training, the user's upper limbs apply force to the handrail assembly, and this force acts on the first force sensor, which collects the force data of the user's upper limbs through the handrail assembly.

[0008] The lower limb training mechanism includes a lower limb training frame suitable for user seating and a second force sensor for collecting force data. The lower limb training frame is movably mounted on the equipment base, and the second force sensor is located between the lower limb training frame and the equipment base. The data output terminal of the second force sensor is communicatively connected to a data analysis and processing module. When the user's lower limbs move relative to the equipment base, the force is applied to the second force sensor, and the second force sensor collects the force data of the user's lower limbs through the lower limb training frame.

[0009] As a specific embodiment, the armrest assembly is movably connected to the upper limb training frame via a movable rod. One end of the movable rod is connected to the upper limb training frame by swinging up and down, and the other end of the movable rod is connected to the armrest assembly. The middle part of the movable rod is connected to the upper limb training frame via a support assembly. A first force sensor is set between the movable rod and the support assembly. The support assembly supports the armrest assembly at least when the armrest assembly is not subjected to external force. When the user is training, the user applies an upward or downward swinging force to the armrest assembly.

[0010] As another specific solution, the support component includes a power unit and a telescopic rod. The power output end of the power unit is connected to the telescopic rod and drives the telescopic rod to extend or retract. One end of the telescopic rod is hinged to a movable rod, and the other end is hinged to an upper limb training bracket. The extension and retraction of the telescopic rod drives the movable rod to swing and adjust, thereby adjusting the height position of the handrail component.

[0011] As another specific embodiment, the equipment base includes an equipment support, and the upper limb training support is slidably mounted on the equipment support. A position adjustment component for adjusting the distance between the upper limb training mechanism and the lower limb training mechanism is provided between the upper limb training support and the equipment support. The position adjustment component includes an adjustment motor fixed on the equipment support, an adjustment screw rotatably mounted on the equipment support, and a screw nut fixed on the upper limb training support. The motor shaft of the adjustment motor is driven to connect to the adjustment screw to drive the adjustment screw to rotate. The adjustment screw and the screw nut are threadedly connected.

[0012] As another specific solution, one end of the lower limb training bracket is hinged to the equipment base. When the lower limb training bracket swings relative to the equipment base, the second force sensor is subjected to a force in the tensile or compressive direction.

[0013] As another specific solution, an anti-tipping bracket is installed on the base of the equipment. The anti-tipping bracket controls the movement of the lower limb training bracket within a set range. When the lower limb training bracket exceeds the set range of movement, the anti-tipping bracket restricts the excessive movement of the lower limb training bracket.

[0014] As another specific solution, the upper limb training frame is equipped with foot pedals corresponding to the lower limb training mechanism; during lower limb training, the user sitting on the lower limb training frame presses the foot pedals to exert force on the second force sensor.

[0015] As another specific solution, the handrail assembly is movably connected to the upper limb training frame via a movable rod. The handrail assembly is rotatably and adjustablely mounted on the movable rod. The handrail assembly includes a bushing with one or more positioning slots. One end of the movable rod is provided with a connector and a rotating shaft. The rotating shaft is mounted on the connector, and the connector has a flexible positioning clip. The bushing is rotatably fitted onto the rotating shaft and can rotate relative to the connector. When the bushing rotates relative to the connector to a set position, the positioning clip elastically engages with the corresponding positioning slot, thus fixing the handrail assembly relative to the movable rod.

[0016] As another specific embodiment, the handrail assembly also includes a first handrail component and / or a second handrail component. The tubular first handrail component has corresponding bushings connected to both ends, and the tubular second handrail component has a corresponding bushing connected to one end. The first handrail component and / or the second handrail component are rotatable relative to the connecting head.

[0017] As another specific solution, the connector head is provided with a sliding groove, and the positioning card body is slidably mounted on the sliding groove. The positioning card body is provided with an elastic element. Under the action of the elastic element, the positioning card body elastically resets and slides relative to the connector head, and then elastically engages into the positioning slot. The positioning card body is provided with a strip hole, and the connector head is provided with a limiting component. The limiting component passes through the strip hole and is slidable relative to the connector head. The positioning card body is provided with an unlocking mechanism for the user to operate so that the positioning card body disengages from the positioning slot.

[0018] The beneficial effects of this utility model are as follows:

[0019] The upper and lower limb training mechanism in this training device is a highly evolved system regarding how the skeleton responds to applied pressure. It aims to promote and meticulously measure musculoskeletal output in a preset compound isometric position, achieving maximum load on the body to stimulate skeletal muscle and bone density. This load application is similar to performing an extremely intense exercise, but when performed according to instructions, the risk of injury is significantly reduced. In the training mode of this upper and lower limb training device, the applied pressure is created by the user, so the user always has complete control over the force applied and endured by their body, effectively avoiding potential injury.

[0020] In the handrail assembly, the bushing and the rotating shaft are rotatably connected, allowing the first and second handrail components to be adjusted. The position of the handrail assembly can be adjusted by rotation. A locking mechanism is provided between the handrail assembly and the connector, which locks the handrail assembly when adjustment is complete, ensuring its stability during training. The locking mechanism includes a positioning slot on the bushing and a positioning clip on the connector. When the handrail assembly rotates to the set position, the positioning clip engages with the positioning slot, thus locking the handrail assembly relative to the connector. During adjustment, the user can manually disengage the positioning clip from the positioning slot, allowing the handrail assembly to rotate freely. This handrail assembly is adjustable to adapt to different training methods, ensuring the diversity of training programs. Furthermore, its adjustment structure is simple and reasonable, operation is convenient and easy, performance is stable and reliable, and the user experience is excellent.

[0043] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0044] See Figures 1-18 The training device for simulating isometric motion involved in this embodiment includes,

[0045] The equipment base 100 is used to support the entire training equipment.

[0046] The upper limb training mechanism 200 includes an upper limb training support 21, a handrail assembly, and a first force sensor 22 for collecting force data. The upper limb training support 21 is mounted on the top of the equipment base 100. The handrail assembly is movably connected to the upper limb training support 21. The detection end of the first force sensor 22 is connected to the handrail assembly. The data output end of the first force sensor 22 is connected to a data analysis and processing module (not shown in the figure). The data analysis and processing module is the core module for analyzing and processing training data and can calculate relevant parameters based on the data fed back by the first force sensor 22. When a user performs upper limb training, the user's upper limbs apply force to the handrail assembly. This force acts on the first force sensor 22, and the first force sensor 22 collects the force data of the user's upper limbs through the handrail assembly.

[0047] The lower limb training mechanism 300 includes a lower limb training support 31 suitable for a user to sit on and a second force sensor 32 for collecting force data. In this embodiment, the lower limb training support 31 is configured as a seat. The lower limb training support 31 is movably mounted on the top of the device base 100. The second force sensor 32 is disposed between the lower limb training support 31 and the device base 100. The data output terminal of the second force sensor 32 is communicatively connected to a data analysis and processing module. When the user's lower limbs move relative to the device base 100 by the lower limb training support 31, the force is applied to the second force sensor 32, and the second force sensor 32 collects the force data of the user's lower limbs through the lower limb training support 31.

[0048] The upper and lower limb training mechanism in this training device is a highly evolved system regarding how the skeleton responds to applied pressure. It aims to promote and meticulously measure musculoskeletal output in a preset compound isometric position, achieving maximum load on the body to stimulate skeletal muscle and bone density. This load application is similar to performing an extremely intense exercise, but when performed according to instructions, the risk of injury is significantly reduced. In the training mode of this upper and lower limb training device, the applied pressure is created by the user, so the user always has complete control over the force applied and endured by their body, effectively avoiding potential injury.

[0049] Further, see Figures 2-4 The armrest assembly is movably connected to the upper limb training support 21 via a strip-shaped movable rod 221. One end of the movable rod 221 is connected to the upper limb training support 21 by swinging up and down, and the other end of the movable rod 221 is connected to the armrest assembly. The middle part of the movable rod 221 is connected to the upper limb training support 21 via a support assembly. A first force sensor 22 is set between the movable rod 221 and the support assembly. The support assembly supports the armrest assembly at least when no external force is applied. When the user performs upper limb training, the user applies an upward or downward swinging force to the armrest assembly. Using the lever principle, the movable rod 221 transmits the external force to the first force sensor 22. The swinging force applied by the user is finally collected by the first force sensor 22 and fed back to the data analysis and processing module.

[0050] Further, see Figures 2-4The support assembly includes a power unit 24 and a telescopic rod 25. The power output end of the power unit 24 is connected to the telescopic rod 25 and drives the telescopic rod 25 to extend or retract. In this embodiment, the support assembly is preferably an electric push rod. Specifically, the power unit 24 is a servo motor. The telescopic rod 25 includes a fixed sleeve and a movable sleeve. The fixed sleeve is fitted on the outside or inside of the movable sleeve. The servo motor is mounted on the fixed sleeve. The motor shaft of the servo motor is connected to the movable sleeve through a transmission structure such as a gear transmission structure and / or a lead screw transmission structure. When the servo motor is powered on, it drives the movable sleeve to move relative to the fixed sleeve under the transmission action of the transmission structure, thereby realizing the telescopic movement of the telescopic rod 25. The top of the movable sleeve is connected to one end of a first force sensor 22. The other end of the first force sensor 22 is hinged to the movable rod 221. The bottom end of the fixed sleeve is hinged to the upper limb training bracket 21. The extension and retraction of the telescopic rod 25 drives the movable rod 221 to swing and adjust, thereby adjusting the height position of the armrest assembly. By adjusting, it can adapt to different user needs or different training requirements. The top of the telescopic rod 25 is hinged to the middle of the movable rod 221, and the bottom is hinged to the lower part of the upper limb training bracket 21. The telescopic movement of the telescopic rod 25 drives the movable rod 221 to swing and adjust, thereby adjusting the height position of the handrail assembly.

[0051] Further, see Figures 2-4 The upper limb training support 21 is equipped with a touch screen 219, which is connected to a data analysis and processing module. Training instructors (such as coaches, mentors, and other professionals) can input control commands and view relevant training data through the touch screen 219. The movable rod 221 is equipped with a data display screen 218, which is connected to a data analysis and processing module. Trainees can view training data or relevant training guidance information (such as movement demonstrations, error prompts, etc.) through the data display screen 218.

[0052] Further, see Figures 2-4 The equipment base 100 includes an equipment support 11. An upper limb training support 21 is slidably mounted on top of the equipment support 11. A position adjustment component is provided between the upper limb training support 21 and the equipment support 11 to adjust the distance between the upper limb training mechanism 200 and the lower limb training mechanism 300. The position adjustment component includes an adjusting motor 12 fixed to the equipment support 11, an adjusting screw 13 rotatably mounted on the equipment support 11, and a screw nut 14 fixed to the upper limb training support 21. The motor shaft of the adjusting motor 12 is driven by the adjusting screw 13 to drive its rotation. The adjusting screw 13 is threadedly connected to the screw nut 14. By adjusting the front and rear position of the upper limb training support 21, user needs or different training requirements can be met.

[0053] Further, see Figures 5-7The lower limb training bracket 31 is hinged to the top of the equipment base 100 at its rear end. The lower limb training bracket 31 swings back and forth relative to the equipment base 100 around the hinge point. When the lower limb training bracket 31 swings relative to the equipment base 100, the second force sensor 32 is subjected to a force in the tensile or compressive direction, thereby effectively collecting the force data of the user's lower limbs.

[0054] Further, see Figures 5-7 The lower limb training mechanism also includes a support assembly for supporting the front end of the lower limb training bracket 31, ensuring that the lower limb training bracket 31 is supported by the support assembly when no external force is applied. The support assembly includes a first adapter 33 and a second adapter 34. One end of the second force sensor 32 is hinged to the lower limb training bracket 31 via the first adapter 33, and the other end is hinged to the device base 100 via the second adapter 34. The first adapter 33 and the second adapter 34 are coaxially coupled. One end of the first adapter 33 is connected to the second force sensor. One end of the second force sensor 32 is threaded, and the other end is hinged to the lower limb training bracket 31; one end of the second adapter 34 is threaded to the other end of the second force sensor 32, and the other end is hinged to the equipment base 100; when the lower limb training bracket 31 swings backward around the hinge point, the front end of the lower limb training bracket 31 swings upward, and at this time the second force sensor 32 is subjected to a force in the tensile direction; when the lower limb training bracket 31 swings forward around the hinge point, the front end of the lower limb training bracket 31 swings downward, and at this time the second force sensor 32 is subjected to a force in the compressive direction.

[0055] Further, see Figures 5-7 The equipment base 100 is equipped with an upwardly extending anti-tipping bracket 35 at its top. The anti-tipping bracket 35 controls the movement of the lower limb training bracket 31 within a set range. When the lower limb training bracket 31 exceeds the set range of movement, the anti-tipping bracket 35 restricts the excessive movement of the lower limb training bracket 31. That is, when the support component of the lower limb training bracket 31 is damaged during its backward swing, the front end of the lower limb training bracket 31 instantly loses traction. At this time, the anti-tipping bracket 35 can promptly restrict the lower limb training bracket 31 from continuing to swing backward, preventing it from falling backward and causing a safety accident. When the support component of the lower limb training bracket 31 is damaged during its forward swing, the front end of the lower limb training bracket 31 instantly loses support. At this time, the anti-tipping bracket 35 can promptly restrict the lower limb training bracket 31 from continuing to swing forward, preventing it from falling forward and causing a safety accident.

[0056] Further, see Figures 5-7The anti-tipping bracket 35 is provided with a limiting groove 3501, and the lower limb training bracket 31 is provided with a limiting rod 36 at its lower part. The limiting rod 36 is set within the limiting groove 3501 to ensure that the limiting rod 36 can only move within the limiting groove 3501, thereby controlling the range of motion of the lower limb training bracket 31. The limiting rod 36 moves within the limiting groove 3501 as the lower limb training bracket 31 moves. Specifically, the limiting groove 3501 extends laterally, and both extended ends and the front end are respectively opened; the limiting rod 36 extends laterally, and both extended ends pass through the two extended ends of the limiting groove 3501; when the support component is damaged during the backward swing of the lower limb training bracket 31, the top of the limiting groove 3501 acts on the limiting rod 36 to prevent the lower limb training bracket 31 from tilting backward and causing a safety accident; when the support component is damaged during the forward swing of the lower limb training bracket 31, the bottom of the limiting groove 3501 acts on the limiting rod 36 to prevent it from tilting forward and causing a safety accident.

[0057] Further, see Figures 5-7 The lower limb training frame 31 is equipped with a lower limb support bar 37 at its lower part. The lower limb support bar 37 is movable relative to the lower limb training frame 31. When the user is not using the lower limb support bar 37, the lower limb support bar 37 is in the reset position. When the user is resting, the lower limb support bar 37 can be pulled out to support the feet. The lower limb training frame 31 is equipped with a third handrail 38 on each side for the user to hold on to, so that the user can maintain body balance by holding on to the third handrail 38 during training. The lower limb training frame 31 is equipped with a seating part 311 and a backrest 310. The seating part 311 is equipped with a seat belt 39, and the third handrail 38 is equipped on each side of the seating part 311.

[0058] Further, see Figures 5-7 The upper limb training support 21 is equipped with a foot pedal 217 corresponding to the lower limb training mechanism 300. When the user performs lower limb training, the user sitting on the lower limb training support 31 presses the foot pedal 217 to exert force on the second force sensor 32. During the lower limb training, the upper limb training mechanism 200 does not move or adjust to ensure that the foot pedal 217 is relatively fixed, so as to avoid the foot pedal 217 moving and affecting the training effect.

[0059] Further, see Figures 8-18The armrest assembly is movably connected to the upper limb training support 21 via a movable rod 221. The armrest assembly is rotatably and adjustablely located at the end of the movable rod 221. The armrest assembly includes a bushing 222 for connecting the armrest components, and the bushing 222 has two (or more) positioning slots 22201 on its periphery. One end of the movable rod 221 is provided with a connector 223 and a rotating shaft 2601. In this embodiment, two rotating shafts 2601 are provided, and the two rotating shafts 2601 are coaxially arranged on both sides of the connector 223. The connector 223 is provided with... Two flexible positioning clips 27 are provided, corresponding to the bushings 222. The bushings 222 are rotatably fitted onto the outside of the rotating shaft 2601 and are rotatable relative to the connector 223. When the bushings 222 rotate relative to the connector 223 to the set position, the positioning clips 27 elastically engage with the corresponding positioning slots 22201, fixing the handrail assembly relative to the movable rod 221. Users can adjust the handrail assembly according to training needs to meet different training requirements and diversify training programs.

[0060] In the handrail assembly, the bushing 222 is rotatably connected to the rotating shaft 2601, allowing the first and second handrail components to be rotated and adjusted. The position of the handrail assembly can be adjusted by rotation. A locking mechanism is provided between the handrail assembly and the movable rod 221. This locking mechanism locks the handrail assembly when it is adjusted, ensuring its stability during training. The locking mechanism includes a positioning slot 22201 on the bushing 222 and a positioning clip 27 on the connector 223. When the handrail assembly rotates to the set position, the positioning clip 27 engages with the positioning slot 22201, thus locking the handrail assembly relative to the movable rod 221. During adjustment, the user can manually disengage the positioning clip 27 from the positioning slot 22201, allowing the handrail assembly to rotate freely. This handrail mechanism is adjustable to adapt to different training methods, ensuring the diversity of training programs. Furthermore, its adjustment structure is simple and reasonable, operation is convenient and easy, performance is stable and reliable, and the user experience is good.

[0061] Further, see Figures 8-18 The handrail assembly also includes a first handrail component 28 and a second handrail component 29 (the first handrail component 28 and the second handrail component 29 are selected according to actual needs). In this embodiment, the first handrail component 28 and the second handrail component 29 are respectively formed by bending tubular material. The tubular first handrail component 28 is M-shaped, and its two ends are respectively connected to the corresponding bushings 222. The tubular second handrail component 29 is zig-shaped, and one end is connected to the corresponding bushing 222. The first handrail component 28 and the second handrail component 29 are rotatable relative to the connector 223 to meet the needs of different training programs.

[0062] Further, see Figures 8-18The connector 223 has an axially extending groove 22304 on its side wall. The positioning clip 27 is axially slidably mounted on the groove 22304. The positioning clip 27 is provided with an elastic element 210. Under the action of the elastic element 210, the positioning clip 27 elastically resets and slides relative to the connector 223, and then elastically engages in the positioning slot 22201. In this embodiment, two positioning clips 27 are provided. The elastic element 210 is a helical spring and is located between the two positioning clips 27. When one or both positioning clips 27 slide, the elastic element 210 compresses and stores energy, and the positioning clip 27 can disengage from the corresponding positioning slot 22201 to unlock. When the force disappears, the elastic element 210 releases the elastic force, thereby causing the positioning clip 27 to elastically reset and engage in the corresponding positioning slot 22201, thus locking the handrail assembly. The positioning card body 27 has an axially extending strip hole 2701, and the connector 223 is provided with a limiting component 214. The limiting component 214 passes through the strip hole 2701 and is relatively slidable. In this embodiment, the limiting component 214 can be a screw. The limiting component 214 can limit the movement position of the positioning card body 27 by cooperating with the strip hole 2701. The positioning card body 27 is provided with an unlocking part 215 for the user to operate so that the positioning card body 27 is disengaged from the positioning slot 22201.

[0063] Further, see Figures 8-18 The movable rod 221 is provided with a rotating shaft component 26. The rotating shaft component 26 is integrally formed with a rotating shaft 2601 and an adapter 2602 that are coaxially connected to each other. The bushing 222 is rotatably disposed between the adapter 2602 and the connector 223. A first limiting part 22301 is provided on one end face of the connector 223, which acts as a limit on one end of the bushing 222. A second limiting part 2603 is provided on one end face of the adapter 2602, which acts as a limit on the other end of the bushing 222. Under the mutual limiting action of the connector 223 and the adapter 2602, the axial displacement of the bushing 222 is effectively prevented, ensuring that the rotation of the handrail assembly 200 is more stable.

[0064] Further, see Figures 8-18 The connector 223 has axially extending shaft holes 22302 on both sides, which penetrate the corresponding end faces of the connector 223. The other end of the rotating shaft 2601 is inserted into the shaft hole 22302. An anti-rotation component 211 is provided between the eccentric position of the end of the rotating shaft 2601 and the connector 223. The anti-rotation component 211 is inserted into the rotating shaft 2601 and the connector 223 respectively. By providing the anti-rotation component 211, the rotating shaft 2601 is effectively prevented from rotating relative to the connector 223.

[0065] Further, see Figures 8-18The movable rod 221 is provided with a fastening component 212, which is a bolt in this embodiment; the inner side of the rotating shaft 2601 is provided with an axially extending through hole 2604, and the inner side of the connector 223 is provided with an axially extending screw hole 22303. The fastening component 212 passes through the through hole 2604 and is screwed into the screw hole 22303, so that the rotating shaft component 26 and the connector 223 are tightly connected.

[0066] Furthermore, the handrail assembly also includes an axially extending gripping member 213, which is sleeved on the outside of the adapter 2602; the connector 223, bushing 222, rotating shaft member 26 and gripping member 213 are coaxially engaged with each other.

[0067] Training principle:

[0068] This training equipment is based on isometric exercise, which refers to a type of exercise where the muscle length remains constant during contraction and no joint movement occurs. This type of exercise primarily increases muscle tension to counteract fixed resistance; the muscle contracts without shortening its fibers, thus increasing muscle tension without changing muscle length.

[0069] Main functions:

[0070] The training mode of this training equipment is as follows: the pressure applied is created by the user, so the user always has complete control over the force they apply and the force they need to withstand; its effects include, but are not limited to: muscle tension and muscle recruitment, bone density, blood sugar (A1C) and blood lipids, blood circulation and tissue temperature, balance ability, self-confidence, weight loss, etc.

[0071] How to use:

[0072] Calibration location:

[0073] The front-to-back position of the lower limb training mechanism 300 of this training device is fixed. Under system control, the upper limb training mechanism 200 can automatically adjust to move closer to or further away from the user on the lower limb training mechanism 300, while the armrest assembly can be adjusted up and down. After the initial calibration setting, all setting values ​​(including the distance between the upper limb training mechanism 200 and the lower limb training mechanism 300, and the height position of the armrest assembly, etc.) will be saved in the system. After the training is completed, the training device will automatically return to the initial position. During the next training session, the user can always make fine adjustments to the position using the adjustment keys on the touch screen 219 or the data display screen 218.

[0074] Recorded data:

[0075] Users perform four preset compound isometric movements according to the software instructions and record the corresponding data; the initial setting for the duration of each training exercise is preferably 5 seconds, but this duration can be freely selected from the list on the screen or customized.

[0076] Exercise 1, Chest Press:

[0077] See Figure 19 The chest press is a pushing exercise that works the upper arm muscles, including the deltoids, triceps, and pectoral muscles.

[0078] Handrail assembly position adjustment: Adjust the grip component 213 to one inch below the shoulder joint; place the user's hand on the grip component 213 and raise the elbow to an angle parallel to the ground. From the side, the hand, elbow, and shoulder should be on the same plane; if they are not on the same plane, adjust the height of the handrail assembly according to the actual situation; the training equipment will automatically save the height record of the handrail assembly for later use.

[0079] Lower limb training mechanism 300 position adjustment: After completing the armrest assembly height adjustment, it is necessary to determine the position of the lower limb training mechanism 300 when the elbow is flexed (arm bent) at a specified angle. The initial angle should be set between 120° and 135°. The optimal elbow flexion angle can be achieved by adjusting the distance between the lower limb training mechanisms 300 and the lower limb training mechanism 300. After determining the position of the lower limb training mechanism 300, the system will save all user settings for automatic positioning next time.

[0080] Throughout the exercise, the user's feet should remain on foot pedal 217. This is an action that stimulates the upper limb muscles and should not involve any lower limb muscles.

[0081] Hand position: After adjusting the position of the armrest assembly and the lower limb training mechanism 300, the user should ensure that the base of the palm is in contact with the grip component 213, and both hands should be equidistant from the center of the armrest assembly. The thumb should be placed along the axis of the grip component 213, ensuring that the base of the palm is the point of force. After confirming the hand position, the user can place the thumb upward or downward as needed.

[0082] Optimal results: Exhale throughout the training process, focus on pushing the lower limb training support 31 backward to fully mobilize the target muscle groups and achieve the best results. The user should maintain smooth breathing throughout the training process.

[0083] Exercise 2, Leg Press:

[0084] See Figure 20 The leg press is a pressing exercise that primarily works the calf, quadriceps, and glutes. It only requires adjusting the fore-and-aft position of the upper limb training mechanism 200 to fine-tune the lower limb flexion angle, and does not involve upper body movement.

[0085] Upper limb training mechanism 200 position adjustment: Adjusting the position of the upper limb training mechanism 200 will determine the degree of knee flexion, i.e. the knee flexion angle; in most cases, the initial angle should be between 120° and 135°. Adjust the distance of the upper limb training mechanism 200 as needed to achieve the optimal knee flexion; after determining the position of the upper limb training mechanism 200, the system will save all user settings for automatic positioning next time.

[0086] Foot placement: Adjust the upper limb training mechanism 200. Place both feet on the foot pedals 217, shoulder-width apart, with feet, knees, and hips aligned horizontally. Engage the gluteal muscles by pushing with your heels. Throughout the exercise, keep your back in contact with the backrest 310 to prevent injury. Do not train the upper body muscle groups during the entire training process. Place your hands on the third armrest 38.

[0087] Optimal results: Exhale throughout the process and focus on pushing the lower limb training support 31 backward to fully engage the target muscle groups and achieve the best results; never hold your breath and maintain smooth breathing throughout the training process.

[0088] Exercise 3, Core Stretch:

[0089] See Figure 21 Core stretching is a compound stretching exercise that works the biceps and thigh muscles (as stabilizing muscles) in the upper body and the deep abdominal muscles and hip flexors in the lower body. When doing this exercise, the upper body training mechanism 200 and the armrest components should be very close to the user.

[0090] Upper limb training mechanism 200 position adjustment: Adjust the position of the upper limb training mechanism 200 until the user can grasp the "V" shaped part in the middle above the first armrest 28 and support the forearm on the bushing 222; After the position of the upper limb training mechanism 200 is determined, the system will save all the user's settings for automatic positioning next time.

[0091] Handrail assembly position adjustment: Raise / lower the first handrail component 28 until the user's forearm is at 90° to the ground, the back arm is parallel to the ground, and the back is perpendicular to the ground.

[0092] Using seat belt 39: The seat belt 39 should be fastened securely above the user's knees.

[0093] Optimal results: Core stretching is not a pull-up, so during the exercise, the head should not be raised. While pulling the arms down, the user should lift both feet off the ground and try to "touch the knees with the elbows, and at the same time try to lift the knees to the elbows", similar to the method of crunches.

[0094] Exercise 4, Vertical Press:

[0095] See Figure 22 The vertical press is a pressing exercise that primarily works the trapezius, erector spinae, forearm, and hamstrings.

[0096] Upper limb training mechanism 200 position adjustment: Select "Vertical Press" mode from the screen, and the upper limb training mechanism 200 will move back to its original position.

[0097] Handrail assembly position adjustment: The user unlocks the unlocking part 215 to rotate and adjust the position of the second handrail piece 29 until the handle on the second handrail piece 29 is approximately parallel to the ground.

[0098] User Position: First-time users must determine the appropriate height of the second handrail 29. The user walks to the handrail assembly, places both hands on both sides of the body, separates the feet shoulder-width apart, and extends the fingers to the ground. Adjust the second handrail 29 to the bottom of the longest finger. The user bends the knees and hips while keeping the arms straight so that they can firmly grasp the grip of the second handrail 29. The user squeezes the shoulder blades together, the purpose of which is to lift with the legs rather than pulling with the arms. Once the user is ready, they can begin the vertical press.
