ABSTRACT:
An exercise device having a frame, a seat and a back rest mounted on the frame and a weight stack having a plurality of movable weights. An elongated resistance convertor arm is rotatably mounted on the frame and a cable having one end connected to the weights in the weight stack and the other end connected to the resistance converter arm. A movable contact member adapted to be moved by a user of the exercise device is rotatably mounted on the frame and an adjustment disk connects the contact member and the resistance convertor arm so that the relative angular position of the resistance convertor arm and the horizontal plane including the contact member can be varied to change the pattern of resistance to movement of the contact member.
