Loop Band Shoulder Internal Rotation
The Loop Band Shoulder Internal Rotation is a resistance band exercise designed to strengthen the rotator cuff and improve shoulder stability. By keeping your elbow tucked and rotating your arm inward against tension, you target the subscapularis muscle to prevent injury and improve posture.
Because rotator cuff exercises require precise tension rather than heavy loads, the AI analyzes your RPE to ensure you aren't straining the joint with excessive resistance. If you track pain or previous shoulder injuries, the app learns your specific tolerance and can suggest volume adjustments or alternative mobility work to keep your shoulders healthy. By integrating recovery data like HRV, the AI optimizes your volume to strengthen these stabilizers without overtaxing them before heavy pushing days.
Form Cues
- Pin your elbow firmly against your side
- Rotate your forearm inward across your belly
- Keep your wrist straight and neutral
- Maintain a 90-degree bend in your elbow
- Control the band slowly on the return
- Don't let your elbow drift away from your body
- Don't use your torso to swing the band
- Don't curl your wrist to fake the movement
- Don't shrug your shoulder up toward your ear
- Don't let the band snap your arm back
Common Mistakes
- Flaring the elbow out
- Using too much resistance
- Rotating the torso
- Bending the wrist
- Rushing the eccentric release
Muscles Worked
This exercise primarily targets the subscapularis, a key muscle of the rotator cuff responsible for internal rotation and joint stability. While the anterior deltoid and upper chest assist in the movement, the main goal is to strengthen the deep stabilizers that protect the shoulder capsule during heavier pressing exercises.
