ABSTRACT:
An exercise device is provided with a frame. Two pedal structures are mounted on the frame. One pedal structure is to be driven by one's legs and the other pedal structure is to be driven by one's arms. A mechanical structure interconnects the two pedals structures so that a force applied to one pedal structure will assist in the movement of the other pedal structure. The pedal structures are interconnected by a gear and clutch structure that transmits a force from one pedal structure to the other pedal structure. An engagable/disengagable gear and clutch structure is provided for each pedal structure so that each pedal structure can be selectively engaged or disengaged.
