Start: Attach a stirrup handle to the low pulley. Grab the handle with your nondominant hand and stand facing the weight stack with your dominant foot about 12 inches in front of your nondominant one. Plant your forward foot flat on the floor, supporting your weight on that leg. Only the toes of your rear foot should touch the floor-use them just for balance. Your working arm and the cable should form a straight line from shoulder to pulley. Squat down and bend forward at the hips so your rear knee is bent about 45 degrees and your torso forms a 45-degree angle with the floor.
Finish: Stand, pull the handle to the side of your rib cage, and twist to the left. Pause, then slowly return to the starting position. Finish the set that side before repeating on the other.
