1 Attach a stirrup handle to the high cable and stand beside the weight stack as shown.

2 Grab the handle with your inside hand and pull down on the cable so that your palm is in line with your head and your elbow points straight downward.

3 Crunch your rib cage sideways toward your hip bone on the same side as the arm holding the pulley while keeping your hand in the same position relative to your head. Pause, then slowly straighten your back. Finish the repetitions on one side before doing the same on the other side.
