Internal Shoulder Rotation Stretch
Internal Shoulder Rotation Stretch Exercise Description
The Internal Shoulder Rotation Stretch improves mobility of the glenohumeral joint specifically in internal rotation. It primarily targets the posterior shoulder tissues, including the posterior rotator cuff and capsule, which often limit the ability to reach behind the back. Better internal rotation supports comfortable, efficient positioning of the arm during daily tasks and many upper‑body movements. This version uses a gentle towel‑assist to guide the arm without forcing the joint. Move slowly, keep the shoulder blade stable, and work only within a mild, comfortable stretch—never pain.

How To Do The Internal Shoulder Rotation Stretch Exercise
‘- Stand tall with a neutral spine and relaxed neck and jaw.
– Place the target arm behind your lower back with the elbow bent and forearm resting along your back; hold the bottom end of a towel in that hand.
– Reach the other hand over the same-side shoulder to grab the top end of the towel (like a backpack strap).
– Set the target-side shoulder blade: lightly draw it down and back to avoid shrugging.
– Gently pull upward on the towel with the top hand to guide the lower hand higher along your back, creating internal rotation at the shoulder.
– Keep the chest facing forward; avoid twisting the torso or cranking the arm.
– Maintain a neutral wrist and keep the elbow of the bottom arm pointing down.
– Stop at a mild to moderate stretch in the back of the shoulder—no pinching at the front.
– Breathe steadily and release the tension slowly before switching sides.
– No towel available? Use the top hand to lightly assist the wrist of the arm behind your back, following the same cues.
Internal Shoulder Rotation Stretch Tips
‘- Stand tall with a neutral spine and keep your neck and jaw relaxed throughout the stretch.
– Before pulling, lightly draw the target-side shoulder blade down and back to avoid shrugging.
– Use the top hand to gently pull the towel upward, guiding (not forcing) the lower hand higher along your back.
– Keep your chest facing forward and avoid twisting your torso as you stretch.
– Maintain a neutral wrist on the bottom arm and keep that elbow pointing straight down.
– Work only to a mild to moderate stretch in the back of the shoulder—avoid any pinching sensation at the front.
– Breathe steadily as you hold the stretch and move in and out of it.
– Release the towel tension slowly instead of letting it snap back.
– If you don’t have a towel, use the top hand to lightly assist the wrist of the arm behind your back, following the same alignment and stretch cues.
Internal Shoulder Rotation Stretch Beginner Introduction
The Internal Shoulder Rotation Stretch is a gentle mobility drill for the shoulder joint that emphasizes the back of the shoulder and the small stabilizing muscles around it. The movement centers on turning the upper arm inward, especially in the position commonly used when reaching a hand up along the spine. This pattern often feels limited or tight, so this stretch aims to create more ease for actions like tucking in a shirt, fastening a bra, or positioning the arm comfortably for many upper‑body exercises.
In this version, a towel acts as a light assist, similar to a strap, so the arm behind the body receives guided support rather than forceful pressure. One hand helps the other move gradually, while the shoulder blade on the stretching side stays quiet and steady. The sensation is directed into the back of the shoulder, with an emphasis on a calm, comfortable pull rather than any sharp front‑of‑shoulder feeling. Slow pacing and easy breathing create a relaxed environment for the joint to explore a slightly greater range.
