Adjust cable pulleys to medium low positions. Kneel under attached cable bar while supporting it with both hands. Position body in lower squat position with cable bar on top of shoulders, both feet flat on floor with mid feet in line with both pulleys, knees positioned same direction as feet, back straight and angled forward, and hands grasping bar to each side.
Stand up by extending hips and knees until legs are straight. Squat back down by bending hips back while allowing knees to bend slightly forward, keeping back straight and knees pointed same direction as feet. Descend until thighs are just past parallel to floor. Return and repeat.
Position height of cable bar so moving weight plates make contact with unused weight stack at bottom of squat when hips are slightly lower or same height as knees. Keep head facing forward, back straight and feet flat on floor; equal distribution of weight through forefoot and heel. Knees should point same direction as feet throughout movement.
