- Lie supine on back pad with shoulders under shoulder pad.
Place feet on platform. Extend hips and knees and release lever.
- Flex hips and knees to descend until knees are just short
of complete flexion. Raise sled by extending knees and hips.
- If insufficient hip flexibility forces the pelvis to pull
away from the back pad at the lower portions of the movement,
only lower the sled just short of spinal articulation. Keep knees
pointed same directions as feet. Do not allow heels to raise
off of platform, pushing with both heel and forefoot. Also see

on alternative model.
