Sit at a cable pulldown machine with your thighs secured under the pads and grasp the bar with a slightly wider than shoulder-width overhand grip. Keep your chest up and core engaged as you pull the bar down toward your upper chest by driving your elbows downward. Squeeze your shoulder blades together at the bottom, then slowly return the bar to the starting position with control. Focus on smooth movement and avoiding excessive leaning to effectively target the back muscles.
