An exercise device for use with a medicine ball utilizing a support frame with a seat thereon. A medicine ball track is mounted to the frame and is pivotal to a user selectable position of a plurality of positions at which one end of the track is higher than the opposed track end. A seated user facing away from the track initially places the medicine ball at the elevated track end upon torso rotation in one direction. The incline of the track causes a rolling movement of the ball to the lower track end for recovery by the user upon the user oppositely rotating the torso in order to reach the ball at the lower track end. Either end of the track may be elevated so as to provide a balanced exercise. The degree of elevation of the upper track end is adjustable which varies the speed of the ball rolling movement and thus the speed at which the user must rotate between the ball placement and recovery positions. A selector plate positions and maintains the track at a desired inclination.
