Hubs located at the forward, lower ends of the levers are adapted to hold removable weights to provide a predetermined resistance for an exerciser supported on the seat performing a leg press exercise. The exerciser exerts force from the bottoms of the feet against angled foot pads that are rigidly mounted to the levers, thereby hingedly raising the levers upward and forward. By providing two independently pivotal, weight supporting levers, an exerciser may exercise both legs independently, either in simultaneous motion or alternate motion.Other References
