Lie on declined back pad with hips under weighted sled. Place feet on platform. Raise weight by extending hips and knees. Release dock levers and grasp handles to sides.
Lower sled by flexing hips and knees until knees are just short of complete flexion or just before hips raise up from pad. Return by extending knees and hips. Repeat.
If available, re-engage support lever in extended position before dismounting. Flexible hip flexion is required for fuller range of motion through knee. Lower weight just short of hips, leaving back support. Keep knees pointed same directions as feet. Do not allow heels to raise off of platform, pushing with both heel and forefoot, or center of feet if platform is shorter than length of feet.
