Attach a single handle to a high cable pulley and sit or stand facing the machine. Grip the handle with one arm and start with your arm fully extended overhead. Pull the handle down toward your side by driving your elbow toward your hip while keeping your chest up and core engaged. Squeeze your lat at the bottom, then slowly return to the starting position with control. Perform all repetitions on one side before switching, focusing on controlled movement and minimizing torso sway.
Log your cable one arm lat pulldown sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
