Exercise guide
Resistance Band Standing External Rotation
- Beginner
- Isolation
- Rep-based
- Shoulders
- Upper arms
This isolation exercise specifically targets the infraspinatus and teres minor of the rotator cuff, along with the posterior deltoid, to improve shoulder stability and posture. It is highly effective for correcting muscle imbalances and preventing shoulder injuries by strengthening the external rotators.

Setup
- Anchor a light resistance band to a stable post at elbow height.
- Stand perpendicular to the anchor point with feet shoulder-width apart and a slight bend in the knees.
- Grasp the band with the hand furthest from the anchor, keeping your elbow bent at a 90-degree angle.
- Place a small rolled-up towel between your elbow and your side to ensure the arm stays tucked.
How to do it
- Exhale as you rotate your forearm outward away from your body, keeping your elbow pinned firmly against the towel.
- Continue the rotation until your forearm is pointing away from the anchor, or as far as your range of motion allows without twisting your torso.
- Pause for one second at the peak of the contraction to feel the back of the shoulder engage.
- Inhale as you slowly return the band to the starting position using a controlled 2-3 second tempo.
Form checklist
- Keep the elbow tucked against your side throughout the entire set.
- Maintain a neutral wrist; do not let the band pull your wrist into extension or flexion.
- Keep your shoulders down and back, avoiding the urge to shrug the shoulder upward.
- Ensure the movement comes only from the shoulder joint, not by rotating the hips or spine.
Pro tips
- Focus on the 'mind-muscle connection' by imagining your humerus (upper arm bone) rotating like a spit on a rotisserie.
- If you feel the front of your shoulder tensing, reduce the resistance and focus on pulling the shoulder blade toward the spine before starting the rotation.
Make it harder
- Step further away from the anchor point to increase the baseline tension of the band.
- Add a 5-second isometric hold at the point of maximum external rotation.
