Grasp the handle with both hands and extend your arms in front of you. 4. Keeping your back straight, pull the cable toward your upper chest while flaring your elbows out to shoulder height. 5. Squeeze your rear delts and shoulder blades together at the top of the movement. 6. Slowly return to the starting position under control.
