Start: Attach a stirrup handle to the high pulley. With your nondominant hand, grab the handle with an overhand grip. Face the weight stack with your opposite leg slightly bent and a foot or two in front of your nondominant leg. Position yourself so your working arm and the cable form a straight line.
Finish: Pull the handle straight down and back until it reaches your chest and your elbow if behind your torso. Pause then slowly return to the starting position. Finish the set with that arm, then repeat with the other.
