How To Do One Arm Cable Lateral Raise
- Stand next to a cable pulley machine with your feet shoulder-width apart and the handle attachment adjusted to the lowest setting.
- To maintain good posture, push your chest forward, and point your shoulders back while slightly bending both knees.
- Grab the handle and stand straight up with your arm fully extended and feet facing forward. Maintaining a slight bend in your working elbow, raise your arm up to shoulder height.
- Hold for a second, and then slowly lower the weight back to the starting position.
Tips
- Keep your torso still, your back straight, and your elbow slightly bent.
