The forward ends of the levers are adapted to hold removable weights and, during performance of a leg curl exercise, are adapted to be acted upon by the legs of an exerciser supported on the platform. The levers pivot along outer planes of movement that diverge from the front of the frame and tilt inwardly toward the top of the frame, thereby coupling the force applied by the legs against separate weight resistances that move through planes that naturally accommodate the musculoskeletal make-up of a person.Other References
