Cable Bent Over One Arm Lateral Raise
- Intermediate
- Compound
- Rep-based
- Shoulders
This exercise isolates the posterior deltoids and upper back muscles using constant cable tension to improve shoulder stability and rear-shoulder definition. It is highly effective for correcting muscle imbalances and improving posture by targeting the often-neglected rear delts.

Setup
- Set the cable pulley to the lowest position and attach a D-handle.
- Stand sideways to the machine with feet shoulder-width apart and knees slightly bent.
- Hinge at the hips until your torso is nearly parallel to the floor, keeping your back flat and your non-working hand on your thigh or the cable machine for support.
- Grasp the handle with the hand furthest from the machine using a neutral or overhand grip.
How to do it
- With a slight bend in your elbow, exhale as you pull the cable out and up in a wide arc until your arm is level with your shoulder.
- Focus on leading the movement with your elbow, keeping your wrist firm and your torso stationary to avoid using momentum.
- Inhale as you slowly lower the weight back to the starting position, maintaining tension on the muscle throughout the descent.
- Maintain a controlled 2-1-2 tempo, ensuring a brief pause at the top of the movement.
Form checklist
- Keep your back flat and core engaged to prevent spinal rotation or arching.
- Avoid swinging your torso; the only movement should occur at the shoulder joint.
- Keep your neck in a neutral position, looking at a spot on the floor about three feet in front of you.
- Ensure your arm moves directly out to the side, not backward toward your hips.
Pro tips
- Think about 'pushing' the handle away from your body toward the walls to maximize rear delt engagement and minimize trap dominance.
- Stop the movement just before the weight stack touches down to keep constant tension on the deltoid throughout the entire set.
- Experiment with a slight internal rotation (thumb pointing down) to further isolate the posterior head of the deltoid.
Make it harder
- Add a 2-second isometric hold at the peak of the contraction to increase time under tension.
- Perform the eccentric (lowering) phase over a 4-second count to maximize muscle fiber recruitment.
