When the user completes the waist exercise, the elastic force to return to the initial position is applied by the spring 430 installed on the fixed body 410 and the rotating body 420, and the user moves the footrest 210 to the initial position by the elastic force. Since it descends from the footrest 210 in a state to be placed, it always maintains an aligned state.

That is, when the footrest 210 is rotated, it is set to rotate only by 50° in the left or right direction from the initial position, so that it is possible to prevent excessive rotation of the waist during the user's waist movement.

As described above, when the rotation is stopped by the base stopper 130 while the footrest 210, which the user climbs and rotates, rotates only within a maximum of 100°, the elastic force of the cushioning member 310 and the spring 430 is affected. By buffering the shock as much as possible, it is possible to prevent excessive twisting of the waist of users with weak power control, such as children and the elderly, as well as prevent safety accidents caused by excessive rotation of the waist.
