Stand facing a cable machine with a single handle attached at about face height. Hold the handle with one hand and step back to create tension. Keeping your torso upright and core engaged, pull the handle toward your face while driving your elbow outward and back. Focus on squeezing your rear shoulder and upper back at the end of the movement, then slowly return to the starting position with control. Repeat on one side before switching.
