Attach a cable handle to a low pulley and stand sideways to the machine. Grasp the handle with the hand furthest from the machine and place your other hand on your hip. Keep your feet shoulder-width apart and your knees slightly bent. With your abs engaged, bend sideways at the waist, bringing your elbow down towards your hip. Pause for a moment at the bottom, then slowly return to the starting position. Repeat for the desired number of repetitions, then switch sides.
