Sit on machine with back on padded support. Place feet on platform. Grasp handles to sides.
Push platform away by extending knees and hips. Return and 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 emphasizes Gluteus Maximus. Placing feet slightly lower on platform emphasizes Quadriceps.
