Lie on declined back pad with hips under weighted sled. Place both feet on platform. Raise weight by extending hips and knees. Place foot down off of foot platform. Release dock levers and grasp handles to sides.
Lower sled by flexing leg until knees are just short of complete flexion or just before hips raise up from pad. Push weight up by extending knee and hip. Repeat and continue with opposite leg.
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 knee pointed same directions as foot. Do not allow heel to raise off of platform, pushing with both heel and forefoot, or center of foot if platform is shorter than length of feet.
