[0088] First, a user may fix a weight plate of desired weight to the weight unit 130. Additionally, the handle 161 may be adjusted and fixed to a desired angle using the handle angle adjustment unit 161. Next, the user may sit on the sitting unit 170 with his/her back to the body frame 120 and adjust the height of the sitting unit 174 to suit the body size of the user. Next, the legs of the user may be fixed by adjusting the angle of the knee support unit 176 using the support angle adjustment unit 177. Depending on the needs of the user, exercise may be performed by gripping the handle 161 with one hand or both hands and lowering the grip unit 160 so that one end of the rotating unit 140 moves from the raised position (see FIG. 8(A)) to the lowered position (see FIG. 8(B)) to lift the weight plate of the weight unit 130. In addition, the aforementioned operation may be implemented while looking at the body frame 120. When the user lowers the grip unit 160 while gripping the same, the rotating unit 140 connected to the grip unit 160 rotates, and the weight unit 130 connected to the connection unit 150 is lifted according to the rotation of the rotating unit 140. When the user wants to change the weight during exercise, the user may change the weight by adjusting the length of the connection unit 50.

[0089] As described above, the vertical pulldown machine according to an embodiment of the present disclosure can increase exercise effectiveness by rotating the grip unit in a straight line above the head of a user.
