Instructions
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
- To lower sled, bend hips and knees until knees are just short
of complete flexion. Raise sled by extending knees and hips.
Repeat.
Comments
- Reengage support lever in extended position before dismounting.
If insufficient hip flexibility forces pelvis to pull away from
back pad at lower portions of movement, only lower 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. Placing feet slightly high on platform
emphasize Gluteus Maximus. Placing feet slightly lower on platform
emphasize Quadriceps.
