Sit on machine with back on padded support. Place feet slightly high on platform. Grasp handles to sides.
Push platform(s) away by extending knees and hips until knees are fully extended. Return until hips are completely flexed. Repeat.
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. Placing feet slightly high on platform emphasize Gluteus Maximus. Placing feet slightly lower on platform emphasize Quadriceps.
