With hips and waist straight, bend knees to allow body to fall backwards as knees come forward. Allow heels to raise from floor. Lower body until knees are almost fully flexed or near floor. Return to original position by extending knees as heels return to floor.
Keep waist and hips straight throughout exercise. Knees should point same direction as feet throughout movement. Sissy Squat can be performed without additional weight until additional resistance is required. Also see Weighted Sissy Squat on apparatus.
