One-Legged Cable Kickback

Hook a leather ankle cuff to a low cable pulley and then attach the cuff to your ankle. Face the weight stack from a distance of about two feet, grasping the steel frame for support. While keeping your knees and hips bent slightly and your abs tight, contract your glutes to slowly "kick" the working leg back in a semicircular arc as high as it will comfortably go as you breathe out.
