When the limit plate 27 is rotated to a vertical state, it can limit the swing of the foot pedal of the treadmill 14, thereby providing the space required for the user to perform pull-ups and back massage.

[0013] Furthermore, to facilitate the overall assembly and disassembly of the pull-up bar grip mechanism and the adjustment of its height on the first riser 2, such as... Figure 5-8 As shown, the pull-up bar grip mechanism includes a horizontally arranged grip tube 28. Short sleeves 29 are screwed to both ends of the grip tube 28 along its length. Hooks 30 are welded to the short sleeves 29. Several horizontally arranged limiting posts 31 are installed on the upper part of the first upright tube 2. The limiting posts 31 are positioned at different heights on the first upright tube 2. When the hooks 30 are attached to the limiting posts 31, the pull-up bar grip mechanism is fixed at a designated height on the first upright tube 2. A connecting rod 32 is provided inside the grip tube 28. Sliding sleeve brackets 33 are detachably installed at both ends of the connecting rod 32 extending from the grip tube 28 via screws. A vertically arranged guide sleeve 34 is installed on the front side of the sliding sleeve bracket 33. A first guide post 35, which mates with the guide sleeve 34, is installed at the front end of the upper part of the first upright tube 2. A figure-eight handle bar 36 is detachably connected to the sliding sleeve bracket 33 via screws. A rotatable first handle bracket 37 is also installed on the bottom limiting post 31.

[0014] All the above components can be disassembled and assembled. The short sleeves 29 at both ends of the grip tube 28 along its length can be removed to facilitate the installation of rubber grip sleeves on the grip tube 28. The hooks 30 at both ends of the grip tube 28 along its length are arranged in parallel and can be adjusted synchronously to attach the upper limit post 31 at different height positions. The grip tube 28 can rotate relative to the internal connecting rod 32. During the rotation, the hooks 30 can be attached to and detached from the limit post 31. After attachment, the downward force on the pull-up grip mechanism during use makes the attachment of the hooks 30 and the limit post 31 more stable. When the grip tube 28 is adjusted in height, it can drive the internal connecting rod 32 to rise and fall vertically together. The cooperating first guide post 35 and guide sleeve 34 can guide the vertical movement of the grip tube 28. The sliding sleeve bracket 33 and the connecting rod 32 can be disassembled and assembled, and the figure-eight handle 36 and the sliding sleeve bracket 33 can be disassembled and assembled, which facilitates the installation of the overall structure between the first upright tube 2 and the first guide post 35 on both sides.

[0015] Furthermore, such as Figure 10-12The diagram shows the structure of this utility model, which adds weight to assist exercise, allowing for a thorough workout of the user's upper limbs and back. The top of the stand 11 has a horizontally arranged platform plate 38. Between the platform plate 38 and the base plate 1, two vertically arranged counterweight guide rods 39 are provided. A vertically adjustable counterweight bracket 40 is mounted on each counterweight guide rod 39. A first pulley 41 is installed on the upper part of the counterweight bracket 40, and several detachable counterweight blocks 42 are provided on the lower part of the counterweight bracket 40. The number of counterweight blocks 42 that can be hung on the lower part of the counterweight bracket 40 can be selected according to the weight requirements of the workout.

[0016] To enable vertical lifting and lowering of the counterweight support 40 during exercise, two sets of second pulleys 43 are installed side by side on the platform plate 38, a third pulley 44 is installed on the upper part of the first vertical pipe 2, and a fourth pulley 45 and a fifth pulley 46 using the same pulley frame are provided on the outer side of the middle part of the first vertical pipe 2. The fourth pulley 45 is located above the fifth pulley 46, and a sixth pulley 47 and a seventh pulley 48 using the same pulley frame are fixedly installed on the front side of the first vertical pipe 2. The sixth pulley 47 is located above the seventh pulley 48.

[0017] A first transmission rope 49 is fitted onto the first pulley 41. The two ends of the first transmission rope 49 pass over the upper ends of the second pulley 43 and the third pulley 44, the lower end of the fourth pulley 45, and the upper end of the seventh pulley 48, respectively. A first limiting ball 50 is installed at the end of the first transmission rope 49 that passes through the seventh pulley 48. The first limiting ball 50 can be engaged between the pulley frames of the sixth pulley 47 and the seventh pulley 48. A second handle 51 is also installed on the first limiting ball 50. When the user pulls the second handle 51 on both sides, guided by the seventh pulley 48, the fourth pulley 45, the third pulley 44, and the second pulley 43, the first transmission rope 49 can vertically move the counterweight support 40 with the first pulley 41 upwards. Repeatedly pulling the second handle 51 can overcome the weight of the counterweight 42 to exercise the user's upper limbs and back.

[0018] A second transmission rope 52 is also installed on the fifth pulley 46 on one side. An eighth pulley 53 is installed at the lower part of the first vertical tube 2. One end of the second transmission rope 52 is fixedly connected to the pulley frame of the eighth pulley 53, and the other end of the second transmission rope 52 passes around the bottom of the eighth pulley 53 and is equipped with a second limiting ball 54. The second limiting ball 54 can be locked outside the pulley frame of the eighth pulley 53. A pull rope 55 is also connected to the second limiting ball 54. The pull rope 55 is designed to provide the user with upper limb exercise in a seated position. When the pull rope 55 is pulled, the pulley frames of the fourth pulley 45 and the fifth pulley 46 can be moved down through the transmission of the second transmission rope 52. Since one end of the first transmission rope 49, which is attached to the first transmission rope 49, is limited by the first limiting ball 50, the downward movement of the pulley frames of the fourth pulley 45 and the fifth pulley 46 will drive the counterweight support 40 to move vertically upward, thus also achieving the function of adaptive adjustment according to the user's exercise weight.

[0019] Furthermore, such as Figure 13-17 The diagram shows a structural schematic of adding a counterweight and then installing an auxiliary pull-up mechanism. An auxiliary pull-up mechanism that can be vertically raised and lowered is also installed on the first transmission rope 49. When the auxiliary pull-up mechanism is positioned in the height direction, it can be used as an auxiliary platform, allowing the user to kneel on it for pull-up exercises. When the auxiliary pull-up mechanism can be vertically raised and lowered, it can also move the counterweight support 40 upwards under the transmission action of the first transmission rope 49, and then provide the user with auxiliary force for pull-ups with the assistance of the counterweight support 40 falling under its own weight.

[0020] To achieve the above functions, the auxiliary pull-up mechanism includes two sets of first pulley boxes 56 arranged side by side. A rotatable seat plate 57 is hinged to the lower part between the two first pulley boxes 56. The seat plate 57 can rotate to a horizontal position to provide support for the user, and can also rotate to a vertical position to avoid occupying extra space when the auxiliary pull-up mechanism is not in use. A support plate 58 is provided at the bottom of the first pulley box 56. When the seat plate 57 is on the support plate 58, it is in a horizontal position. The support plate 58 serves to limit the horizontal movement of the seat plate 57.

[0021] A support plate 59 is installed inside the first riser 2. A vertically arranged second guide post 60 is installed between the support plate 59 and the base plate 1. A through hole 61 is provided in the first pulley box 56 to cooperate with the second guide post 60. Clamping guide wheels 62 that cooperate with the second guide post 60 are also installed in the first pulley box 56 on both sides of the through hole 61, allowing the first pulley box 56 and the base plate 57 to be vertically raised and lowered relative to the second guide post 60 under stable guidance. The upper end of the second guide post 60 can be detachably installed on the support plate 59 by screws. A screw rod can be set at the bottom of the second guide post 60. An iron pad that allows the screw rod to pass through can be set on the base plate 1, and a nut is set under the iron pad to fix the bottom end of the second guide post 60 to the base plate 1. A spring can also be fitted at the lower end of the second guide post 60. The bottom surface of the spring is connected to the iron pad on the base plate 1. When the first pulley box 56 moves down to the lower end along the second guide post 60, the spring can play a buffering role and reduce the shock of the exerciser.

[0022] To enable the first transmission rope 49 to be used for hoisting the auxiliary lifting mechanism, a ninth pulley 63 is installed on the outside of the first pulley box 56. A transmission rope limiting wheel 64 is installed on the first vertical pipe 2 on the upper side of the first pulley box 56. A through hole is provided on the support plate 59 to allow the first transmission rope 49 to pass through. A tenth pulley 65 is installed at the upper end of the first vertical pipe 2. After the first transmission rope 49 passes over the upper end of the third pulley 44, it contacts the transmission rope limiting wheel 64 and passes over the lower end of the ninth pulley 63, then passes over the upper end of the tenth pulley 65, and then passes over the lower end of the fourth pulley 45. This is equivalent to adding an auxiliary lifting mechanism between the original third pulley 44 and fourth pulley 45. The first transmission rope 49 can drive the first pulley box 56 to move vertically up and down along the second guide post 60.

[0023] When using the assisted pull-up mechanism for pull-up exercises, the first pulley box 56 needs to be vertically raised and lowered relative to the second guide post 60. At this time, the seat 57 also needs to be in a horizontal state so that the user can stand or kneel on the seat 57. When the user is on the seat 57, the seat 57 and the first pulley box 56 will move downward relative to the second guide post 60 due to the downward pressure of the user's own weight. Driven by the first transmission rope 49, the counterweight support 40 will be pulled upward. When the user does pull-up, the weight on the seat 57 decreases, and the counterweight support 40 falls under its own weight, which will cause the seat 57 to move upward, providing the user with upward assistance, thereby playing a corresponding assisted pull-up role.

[0024] When the vertical lifting of the seat 57 and the first pulley box 56 is not required, that is, when the seat 57 is only used as an auxiliary platform with a certain height for the user to perform pull-ups in a kneeling position, the first pulley box 56 needs to be locked onto the second guide post 60. To achieve this function, a rotatable locking plate 66 is hinged to the outer side of the first pulley box 56. The locking plate 66 has a locking groove 67. Rotating the locking plate 66 allows the locking groove 67 to clamp onto the support plate 59, thus limiting the height of the first pulley box 56 and the second guide post 60. In addition to assisting the user in performing pull-ups, the above structure also allows the user to stand or kneel on the seat 57 and hold the horizontal bar on the upright tube for upper arm support exercises.

[0025] Furthermore, in order to minimize the space occupied by the seat 57 inside the equipment without using the auxiliary pull-up mechanism, that is, to keep the seat 57 in a vertical position, a limiting rod 68 is connected between the first pulley boxes 56 on both sides. One of the first pulley boxes 56 is equipped with a rotatable limiting clip 69. When the seat 57 rotates to contact the limiting rod 68, the seat 57 is in a vertical position. Flipping the limiting clip 69 can clamp and limit the frame of the seat 57, that is, maintain the vertical position of the seat 57. Unless the limiting clip 69 is flipped outward, the seat 57 will not be affected by external forces and will always remain in a vertical position, minimizing the exercise space occupied inside the equipment. The upright of the walking machine 14 and the handrail of the lower layer of the fitness frame can be detachably connected. The lower handrail of the fitness frame is equipped with a connecting rod, the end of which can be drilled and threaded. There are screw mounting holes under the handrail. When installing the auxiliary pull-up mechanism on the fitness frame, the upright of the walking machine 14 can be removed to avoid interference during installation and use.

[0026] Furthermore, such as Figure 18-20 As shown, another height-adjustable pull-up bar mechanism includes a swing bar 70 hinged to the second riser 3. A grip tube 28 is detachably installed between the ends of the two swing bars 70 away from the second riser 3 by screws. Corresponding to the position of the grip tube 28, a figure-eight handle bar 36 is also detachably installed at the end of the swing bar 70 by screws. The user can grip the grip tube 28 or the figure-eight handle bar 36 to perform pull-up exercises.

[0027] To allow for height adjustment of the grip tube 28 and the figure-eight handle 36, an arc-shaped adjustment plate 71 is installed on the front side of the first upright tube 2. The arc-shaped adjustment plate 71 has several height limiting holes 72, arranged in a circle with the hinge point of the swing rod 70 as the center. A long sleeve 73 is also provided between the two swing rods 70 on both sides, and two locking rods 74 are installed inside the long sleeve 73. Each locking rod 74 can enter the height limiting hole 72 to position the swing rod 70 on the arc-shaped adjustment plate 71. An adjustment handle 75 is detachably installed on the locking rod 74 via screws. A long strip clearance groove 76 is provided on the long sleeve 73 to cooperate with the adjustment handle 75. A spring 77 is installed between the two locking rods 74, and the spring 77 always tends to push the two locking rods 74 into the height limiting holes 72 on the arc-shaped adjustment plate 71.

[0028] In use, due to the pushing force of the spring 77 on the locking rods 74 on both sides, the locking rods 74 can be positioned within the height limiting hole 72, keeping the grip tube 28 relatively locked at a certain height position on the arc-shaped adjustment plate 71. When it is necessary to adjust the height of the grip tube 28, both hands grasp the adjustment handles 75, overcoming the elastic force of the spring 77 to move the adjustment handles 75 closer together. When the locking rods 74 on both sides disengage from the height limiting hole 72, the swing rod 70 loses its lock and can rotate relative to the arc-shaped adjustment plate 71 for adjustment. After the grip tube 28 moves to the specified height position, adjust the position of the locking rods 74 to align with the height limiting hole 72. The user no longer applies a force to move the adjustment handles 75 closer together. Under the elastic force of the spring 77, the locking rods 74 on both sides can re-enter the height limiting hole 72 to achieve height position locking.

[0029] Both types of pull-up grip mechanisms have adjustable grip tubes 28 at multiple height positions to accommodate users of different heights. Both are designed with figure-eight handles 36, expanding their usability to some extent. In the aforementioned pull-up grip mechanisms, a hanging hole is also provided at the front end of the swing bar 70, into which an elastic rope 85 is installed. Corresponding to pull-up grip mechanisms that use hooks 30 to adjust height, hanging holes can also be provided on the sliding bracket 33, and elastic ropes 85 can be connected and installed via locking hooks, providing users with different exercise methods.

[0030] Furthermore, a pedal height adjustment mechanism is installed between the stepper 8 and the first crossbar 4, such as... Figure 21As shown, the pedal height adjustment mechanism includes vertical plates 78 arranged side-by-side on the first crossbar 4. A long vertical groove 79 is formed at the lower end of the vertical plate 78. A first threaded sleeve 80 is horizontally arranged on the pulley frame of the stepper 8, and a second threaded sleeve 81 is welded vertically to the first threaded sleeve 80. Connecting bolts 82 are fitted at both ends of the first threaded sleeve 80 along its length. The studs of the connecting bolts 82 can pass through the long vertical groove 79 and connect with the first threaded sleeve 80. The diameter of the bolt head of the connecting bolt 82 is larger than the width of the long vertical groove 79. Under the guiding action of the connecting bolts 82 and the long vertical groove 79, the first threaded sleeve 80 and the pulley frame can move vertically within the long vertical groove 79.

[0031] A flat plate 83 is also provided on the first crossbar 4 between the two vertical plates 78. An adjusting bolt 84 that mates with the second threaded sleeve 81 is installed on the flat plate 83. A through hole is provided on the flat plate 83 so that the stud of the adjusting bolt 84 can pass through. The diameter of the screw head of the adjusting bolt 84 is larger than the diameter of the through hole and is located on the upper side of the flat plate 83. Rotating the adjusting bolt 84 causes the second threaded sleeve 81 to rise and fall vertically, which adjusts the height position of the pulley frame of the stepper 8 in the long vertical groove 79, thereby realizing the function of adjusting the height movement range of the pedal.

[0032] Furthermore, another structure for the pull-up bar grip mechanism is as follows: Figure 22-24 As shown, the mechanism includes a horizontally arranged grip tube 28. Short sleeves 29 are screwed to both ends of the grip tube 28, and hooks 30 are welded to the short sleeves 29. Several limiting slots 86 are formed at the front of the first upright tube 2, positioned at different heights on the first upright tube 2. The ends of the hooks 30 have grooves 87 that match the wall thickness of the first upright tube 2. When the grooves 87 are engaged with the lower end of the limiting slots 86, the pull-up grip mechanism is fixed at a designated height on the first upright tube 2. A connecting rod 32 is located inside the grip tube 28. Sliding sleeve brackets 33 are detachably installed at both ends of the connecting rod 32 extending from the grip tube 28 via screws. A vertically arranged guide sleeve 34 is installed on the front of the sliding sleeve bracket 33. A first guide post 35, cooperating with the guide sleeve 34, is installed at the upper front end of the first upright tube 2. A figure-eight handle 36 is also detachably connected to the sliding sleeve bracket 33 via screws.

[0033] and Figure 5The grip mechanism for pull-ups is similar, except that the limiting mechanism of the grip tube 28 is replaced by a limiting slot 86 on the first vertical tube 2 and a locking groove 87 at the end of the hook 30. Under its own weight, the locking groove 87 of the hook 30 is positioned and locked onto the tube wall at the bottom of the limiting slot 86, thus limiting the height. When the height position needs to be adjusted, simply lift the grip tube 28 upwards to separate the locking groove 87 from the tube wall, then rotate the grip tube 28 to separate the end of the hook 30 from the limiting slot 86. Subsequently, under the guidance of the guide sleeve 34, the grip tube 28 can be adjusted vertically. The above structure is both practical and material-saving.

[0034] Furthermore, in order to use the rotating disc 15 in smaller rooms, such as... Figure 25 As shown, the rotating disc 15 is mounted on a long pole frame 88 via a rotating shaft. A fixed clamp 89 is provided at the end of the long pole frame 88, and a detachable movable clamp 90 is bolted to the fixed clamp 89. The fixed clamp 89 and the movable clamp 90 can be fitted together on the first upright pipe 2. The rotating disc 15 can be adjusted in position with the first upright pipe 2 as the center. The rotating disc 15 can be rotated to a position on the upper side of the base plate 1 that does not interfere with movement. This structure can be used in smaller rooms to increase exercise options. An adjustable leg restraint shaft can also be provided at the bottom of the first upright pipe 2. The material can be foam. When using a pull grip in a seated position to exercise upper limb strength, it can be placed above the knees and thighs to assist in standard upper limb pull-down movements.

[0035] Furthermore, such as Figure 26 As shown, a pin 91 is also installed on one side of the foot pedal of the walking machine 14. The base plate 1 has a socket that cooperates with the pin 91. When the pin 91 enters the socket, it can limit the foot pedal of the walking machine 14 on the base plate 1 to prevent the foot pedal from swinging and injuring other users.

[0036] Furthermore, such as Figure 27-31 As shown, corresponding to the position of the second limiting ball 54, a rowing machine device is installed on the first riser 2. The rowing machine device includes a hinge seat 92 located at the lower part of the first riser 2. A support beam 93 capable of horizontal rotation is installed on the hinge seat 92. A vertically arranged support column 94 is installed at the bottom of the support beam 93 to realize the rotational adjustment of the horizontal position of the rowing machine device.

[0037] At the bottom of the support beam 93, a horizontally arranged central shaft 95 and a limiting shaft 96 are provided. Rotatable foot pedals 97 are installed on both sides of the central shaft 95, located between the central shaft 95 and the limiting shaft 96. The limiting shaft 96 can limit the rotation of the foot pedals 97. At the end of the support beam 93, a vertically rotatable crossbeam 98 is also installed. A seat cushion 99 that can move along the length direction is installed on the crossbeam 98. The bottom of the seat cushion 99 is provided with a roller frame 100 that cooperates with the crossbeam 98. When the user sits on the seat cushion 99 and steps on the foot pedals 97, he can perform the corresponding rowing exercise by pulling the rope 55. To provide rear support for the crossbeam 98, a rotating rear support 101 is also hinged to the end of the crossbeam 98 away from the support beam 93. The rear support 101 and the support column 94 form a support for the rowing machine device.

[0038] The first riser 2 is also equipped with a rotatable limiting hook 102. The end of the crossbeam 98 is equipped with a hanging hole 103 that cooperates with the limiting hook 102. When the limiting hook 102 is located in the hanging hole 103, the crossbeam 98 is in a vertically retracted state relative to the support beam 93. In this retracted state, the rowing machine device can effectively reduce the space occupied. The position of the rowing machine device is horizontally adjustable. Both the crossbeam 98 and the rear support 101 can be folded up to save space. The folding function of the crossbeam 98 can also be used to exercise the strength of the upper and lower limbs. A pull grip can be optionally installed on the rear support 101, or a handle that can replace the pull rope 55 can be attached by hooking it. In addition, counterweights or counterweight items can be hung on the handles on both sides of the rear support 101 to increase the overall weight of the crossbeam 98 and play an effective folding exercise role. The rowing machine device also utilizes the counterweight block 42 on the frame, which increases the range of use of the counterweight block 42 and adds exercise function. In addition, the rowing machine, stepper, waist twisting disc, and abdominal massager can all be switched between left and right, making them convenient for installation and use in different apartment layouts. Walking machines and assisted pull-ups are optional and have corresponding installation functions reserved.

[0039] Furthermore, in order to expand the functionality of this fitness frame, such as... Figures 32-36As shown, a lifting barbell mechanism is installed on the first riser 2. The barbell mechanism includes a vertical rod 104 located on the front side of the first riser 2. Vertically lifting guide sleeve seats 105 are fitted on each of the vertical rods 104. A barbell rod 106 is installed between two guide sleeve seats 105. A rubber sleeve 107 is wrapped around the outer periphery of the barbell rod 106. The guide sleeve seats 105 are connected to the counterweight bracket 40 via a transmission rope. A detachable handle tube 108 and a counterweight tube 109 are also installed on the outside of the guide sleeve seats 105. Several barbell plates 110 are installed on the counterweight tube 109. A rotatable hook rod 111 is hinged to the inside of the guide sleeve seats 105. Several hanging slots 112 are provided on the first riser 2 to cooperate with the hook rod 111. When the hook rod 111 is located in the hanging slot 112, the barbell mechanism can be positioned at a specified height on the vertical rod 104.

[0040] The aforementioned barbell mechanism can vertically rise and fall under the weight of the counterweight support 40. The user's shoulders can be positioned at the bottom of the rubber sleeve 107, overcoming the weight of the counterweight support 40 to perform squat exercises. The barbell plates 110 at both ends of the barbell bar 106 can be added or removed according to the user's needs to adjust the weight for squats. After the barbell bar 106 is raised to a certain height, the hook rod 111 can be rotated into the hanging slot 112 to position the barbell mechanism in the height direction. Rotating the hook rod 111 out of the hanging slot 112 releases the locking state. The user can also push the barbell bar 106 upwards for pressing exercises. When the barbell bar 106 is locked at the height position, the user can use the massage rollers to massage the legs, back, or waist during the squatting process. When used in conjunction with the walking machine 14, it not only increases the stability of the exercise process but also effectively exercises the upper arms and waist.

[0041] The upper part of the first riser 2 and the second riser 3 can also be equipped with hanging plates 113 arranged side by side. Each hanging plate 113 has a through hole, and a detachable extension rod 114 is installed in the through hole. The extension rod 114 extends out of one side of the fitness frame, and auxiliary exercise devices such as swings, punching bags 117, pull-up bars 122 and hanging grip bars 125 can be installed on it. It extends out of one side of the fitness frame, which can effectively increase the exercise space while ensuring the stability of the overall structure.

[0042] One end of the extension rod 114 is connected to the mounting plate 113 via a first pressure plate 115. The first pressure plate 115, the mounting plate 113, and the extension rod 114 are all connected by bolts, ensuring a stable connection while facilitating assembly and disassembly. The other end of the extension rod 114 extending out of the riser is connected to a second pressure plate 116 via bolts. A punching bag 117 is hung at the bottom of the second pressure plate 116. The punching bag 117 can be hung on the second pressure plate 116 via a detachable hook, providing users with boxing training and allowing for removal when not in use.

[0043] Two sets of hangers 118 are also fitted on the extension rod 114. The hangers 118 can move along the length of the extension rod 114, and each hanger 118 can be fastened to the extension rod 114 by bolts. A hook plate 119 is hinged to the bottom of the hanger 118. The hook plate 119 can rotate relative to the hanger 118. A swing lug 120 is suspended on each hook plate 119. A swing seat 121 is hung between the two sets of swing lugs 120, providing users with the recreational function of swinging. The swing lugs 120 can be easily installed and removed from the hook plate 119. When not in use, the swing lugs 120 can be removed and hung in other positions to make room for other exercise structures.

[0044] A pull-up bar 122 is installed between the two sets of hook plates 119. Users can grip the pull-up bar 122 to perform pull-ups or crunches. The position of the pull-up bar 122 can be adjusted by rotating it with the hook plates 119. A second pulley box 123 is also installed on the extension rod 114. The second pulley box 123 can be moved and adjusted along the length of the extension rod 114 and can be fastened to the extension rod 114 with bolts. A transmission rope is installed on the pulley assembly of the second pulley box 123. One end of the transmission rope is connected to the counterweight bracket 40, and the other end of the transmission rope is connected to a hanging grip bar 125 via a hanging chain 124. Users can overcome the weight of the counterweight and pull down the hanging grip bar 125 to exercise their upper limb strength. To facilitate the placement of the hanging grip bar 125, the pull-up bar 122 is also provided with a hook 126 for placing the hanging grip bar 125.

[0045] To prevent interference with the pull-up bar 122 when using the hanging grip bar 125, a flip pulley 127 is installed on one of the hangers 118. A flip rope 128 is installed on the flip pulley 127. One end of the flip rope 128 is connected to the hook plate 119, and the other end of the flip rope 128 passes around the flip pulley 127 and is connected to the flip hook 129. Pulling the flip hook 129 will cause the hook plate 119 and the pull-up bar 122 to rotate upward and move away from the hanging grip bar 125, thereby making room for the hanging grip bar 125.

[0046] To further enhance the stability of the extension rod 114 and ensure its strength when multiple exercise devices are added, an adjustable zipper 130 is installed between the upper end of the riser and a set of hangers 118. One end of the zipper 130 is installed on the upper end of the riser, and a matching long screw 131 is installed on the hanger 118 via a nut. A hanging ring 132 is provided at the end of the long screw 131, and the other end of the zipper 130 is connected to the hanging ring 132. Rotating the long screw 131 can adjust the length of the zipper 130 between the riser and the hanger 118. The length of the zipper 130 can be adaptively adjusted according to the position of the hanging ring 132 on the extension rod 114 to ensure the connection stability between the two zippers 130, which strengthen the extension rod 114, and the overall structure of the fitness frame.

[0047] Furthermore, such as Figure 37 and Figure 38 As shown, the transmission rope can also pass over a steerable pulley mechanism. This pulley mechanism is hinged to the upright tube via a vertically arranged pivot, allowing axial rotation. The transmission rope allows for the use of counterweights to increase the weight of the barbell, and the exerciser can choose the number of counterweights according to their needs. After the transmission rope is separated from the barbell support, it can also be used to attach a pull rope or other resistance grips, thus providing high-position rowing or resistance training in different positions. In other words, the steerable pulley mechanism can provide multi-position resistance training and high-position rowing exercises on a rowing machine.
