cable one arm lateral bent-over

Stand with your feet shoulder-width apart, facing a cable machine. Grasp the handle with one hand and step back to create tension on the cable. Bend forward at the waist, keeping your back straight and your core engaged. Extend your arm out to the side, parallel to the ground, with a slight bend in your elbow. Slowly bring your arm back to the starting position, maintaining control throughout the movement. Repeat for the desired number of repetitions, then switch sides.
