## How to do it

1. Set a single handle on the lowest pulley and stand upright facing the stack, feet shoulder width apart.
2. Take the handle in one hand with an underhand grip and let your arm hang at your side.
3. Bend your elbow to bring the handle up toward your shoulder, keeping your elbow next to your torso.
4. Lower the handle with control, stopping with the arm slightly bent.
5. Finish your reps, then switch sides.
