Sit on machine with back on padded support. Place feet on slightly high on platform. Grasp handles to sides.
Push one platform away by extending knee and hip. Return to original position. Repeat with opposite leg. Continue by alternating between sides.
Adjust seat and back support to accommodate near full range of motion without forcing hips to bend at waist. Keep knees pointed same directions as feet. Do not allow heels to raise off of platform, pushing with both heel and forefoot. This exercise may be performed by alternating (as described), simultaneous, or in simultaneous-alternating fashion.
