cable standing shoulder external rotation

Stand with your feet shoulder-width apart and your knees slightly bent. Hold the cable handle with your arm extended in front of you, parallel to the ground. Keep your elbow slightly bent and your shoulder blades pulled back. Slowly rotate your arm outward, away from your body, while keeping your elbow in the same position. Pause for a moment at the end of the movement, then slowly return to the starting position. Repeat for the desired number of repetitions.
