Abstract
An exercise apparatus having foot beams (38'',40'') rotatably mounted to an upright post member (140'') of a frame (138''). Mounting blocks (242) are rotatably mounted to the upright post member above the foot beams to rotate about a first axis (248), and are linked by tie rods (136'') to the foot beams. Hand levers (132'' and 134'') are mounted to the mounting blocks by elastomeric torsion springs (256). Downward rotation of a foot beam results in rotation of the corresponding linked mounting block and hand lever about the first axis. Differential force exerted on the hand lever relative to the foot beam results in rotation of the hand lever about a second axis (284) and storage of energy by the elastomeric torsion spring. The hand lever is urged back to its nominal position by release of the stored energy.
