ABSTRACT:
A machine for bi-directional exercising of a muscle group through movement of lever arms against a selected resistance has a sub-frame mounted to a main-frame, for pivotal movement about a generally horizontal axis, and the levers connected to the sub-frame to pivot on a pair of spaced apart right and left pivot axes axially displaced to provide a moment arm about the horizontal axis. The lever arms each have a pedal, oriented to effect pivotal movement of the sub-frame about the horizontal axis, and a knee pad, oriented to effect pivotal movement of the lever arms about their respective right or left pivot axis. Linkage members connect each lever arm to the main-frame so that, as the sub-frame pivots through a given angle, the lever arms pivot through opposing angles, and a force applied to either the pedals or knee pads will move the sub-frame and lever arms through their respective angular ranges.
