The seat portion 174 may be made of a material that allows the user to feel cushioning.

[78] The height adjustment portion 175 may connect the second seating frame 172 and the seat portion 174, and may be provided to slide in a height direction along the second seating 20 frame 172 or to be fixed to the second seating frame 172. The user can exercise in a more comfortable state by adjusting the height adjustment portion 175 to change the height of the seat portion 174 from the floor.

[79] The knee support portion 176 may be mounted to the first seating frame 171, and may be disposed higher than the seat portion 174 to be placed above the knees of the user 25 seated on the seat portion 174. The knee support portion 176 may be provided with a pair of12 knee support pieces (not shown) for securing both thighs or knees of the user.

[80] The support angle adjustment unit 177 can adjust the angle of the knee support portion 176 with respect to the first seating frame 171. The first angle adjustment unit 162, the second angle adjustment unit 163, and the support angle adjustment unit 177 may be 5 provided with a plurality of angle adjusting holes (not shown) having a circular arc shape, and may be adjusted at desired angle by inserting an angle fixing pin into one of the plurality of angle adjusting holes. By providing the support angle adjustment unit 177, it is possible to respond to the body sizes of various users using the high-low machine 100.

[81] Referring again to FIGS. 1 and 2, the mounting portion 180 may be provided to 10 protrude at a preset angle at one point of the support frame 110, and may be provided to define a lowering limit of the weight portion 130.

[82] Hereinafter, the operation of the high-low machine 100 of the present disclosure will be described with reference to FIGS. 9A and 9B.

[83] FIGS. 9A and 9B are diagrams showing the operation of the high-low machine 15 according to one embodiment of the present disclosure.

[84] FIG. 9A shows a state before the user lowers the grip unit 160, and FIG. 9B shows a state after the user lowers the grip unit 160.

[85] First, the user can fix a weight plate of desired weight to the weight portion 30. In addition, the user can adjust and fix the handle 161 at a desired angle using the first angle 20 adjustment unit 162 and the second angle adjustment unit 163. Next, the user sits on the seating unit 170 with his back toward the main body frame 120 and can adjust the height of the seating unit 174 to suit the user's body size. Then, the user can adjust the angle of the knee support portion 176 using the support angle adjustment unit 177 to fix his/her legs. Depending on the user's needs, the user can exercise by lowering the grip unit 160 while 25 gripping the handle 161 with one or both hands to move one end of the rotating portion 14013 from the raised position (see FIG. 9A) to the lowered position (see FIG. 9B) so that the weight plate of the weight portion 130 is lifted. As a matter of course, the above-described operation may be implemented in a state that the user faces the main body frame 120. When the user lowers the grip unit 160 while gripping it, the rotating portion 140 connected to the 5 grip unit 160 rotates, and the weight portion 130 connected to the connecting portion 150 is lifted according to the rotation of the rotating portion 140. When it is desired to change the weight during exercise, the weight can changed by adjusting the length of the connecting portion 150.

[86] As described above, according to one embodiment of the present disclosure, the first 10 angle adjustment unit and the second angle adjustment unit are respectively provided based on two axes orthogonal to the grip unit, so that the user can adjust the handle angle at various angles and select the grip method according to the user's needs to target his/her specific body portion for intensive exercise.

[87] In addition, the user can perform exercise using the high-low machine according to 15 one embodiment of the present disclosure by selecting one arm motion or both arm motion, so that customized motion can be performed according to the purpose of exercise, and the user can adjust the height of the seat portion, the angle of the knee support portion, and the like, so that it can respond to the body sizes of various users.

[88] Although one embodiment of the present disclosure has been described above by 20 way of limited examples and drawings, the present disclosure is not limited to the abovedescribed embodiment, and various modifications and variations can be made from these descriptions by one having ordinary skill in the art to which the present disclosure pertains. Accordingly, the present disclosure should be understood only by the scope of the claims set forth below, and all equivalent or equivalent modifications thereof shall fall within the scope 25 of the idea of the present disclosure.14 [89] (Reference Numerals) 100: high-low machine 110: support frame 120: main body frame 5 130: weight portion 140: rotating portion 150: connecting portion 160: grip unit 170: seating unit 10 180: mounting portion
