Sled Hack Squat

Preparation
Lie supine on back pad with shoulders under shoulder pad. Place feet on platform slightly higher than base of sled. Extend hips and knees. Release dock levers.

Execution
Flex hips and knees to descend until knees are just short of complete flexion. Raise sled by extending knees and hips. Repeat.

Comments
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.
