|Utility:||Basic or Auxiliary|
Sit on sled with back of hips against back pad. Place feet on platform shoulder width or slightly wider. Extend hips and knees. Release dock lever(s).
Lower sled by flexing hips and knees until either is near complete flexion. Raise sled by extending knees and hips. Repeat.
If available, re-engage 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.
