The Shoulder Stretch Behind the Back with Towel is a standing mobility exercise that uses a towel to bridge the gap between your hands when you cannot clasp them directly. The top arm stretches the anterior shoulder, chest, and biceps, while the bottom arm targets the rotator cuff and posterior shoulder. It is an accessible variation of the Apley scratch stretch and a practical tool for improving overall shoulder range of motion.
How to do the Shoulder Stretch Behind the Back with Towel
- 1Stand tall with your feet hip-width apart and hold one end of a towel in your right hand.
- 2Raise your right arm overhead, bend the elbow so your right hand drops behind your head, and let the towel hang down your back.
- 3Reach your left arm behind your lower back and bend the elbow upward so your left hand can grasp the lower end of the towel.
- 4Gently walk your hands closer together along the towel until you feel a moderate stretch in both shoulders — stop before any pain.
- 5Hold the position for 20–30 seconds, breathing slowly and letting the shoulders relax deeper into the stretch with each exhale.
- 6Release the towel, lower both arms, and shake them out briefly.
- 7Switch sides: raise your left arm overhead and reach your right arm up from below, then repeat the same hold.
Form tips
- Keep your top elbow pointing straight up toward the ceiling rather than drifting forward, which keeps the stretch on the shoulder rather than the neck.
- Use the towel as a guide, not a pulley — avoid aggressively yanking one hand toward the other, as this can strain the rotator cuff.
- Stand or sit against a wall to prevent your lower back from arching as you reach behind your head.
- Compare both sides after each session; a significant difference in hand distance often indicates tightness worth addressing with a physio.
Common mistakes
- Pulling forcefully on the towel to force the hands together, which can impinge the shoulder and cause injury instead of a productive stretch.
- Letting the top elbow drift forward and out to the side, which reduces the stretch on the anterior shoulder and shifts tension onto the neck.
- Holding your breath during the hold, which keeps muscles tense and limits how far the stretch can progress.
- Rushing through the hold without giving connective tissue time to respond — a hold shorter than 20 seconds rarely produces lasting mobility gains.
- Ignoring pain or sharp sensations and pushing through them, which can worsen existing rotator cuff irritation.
Frequently asked questions
What muscles does the Shoulder Stretch Behind the Back with Towel target?
The top arm stretches the anterior deltoid, pectoralis major, and biceps. The bottom arm targets the posterior deltoid, rotator cuff muscles (particularly infraspinatus and teres minor), and the muscles of the upper back. Together, both arms receive a complementary stretch that addresses the full range of shoulder mobility.
How long should I hold the stretch?
Hold each side for 20–30 seconds per repetition. Perform 2–3 repetitions per side. For tight shoulders, longer holds of up to 60 seconds can be beneficial, provided there is no pain.
Why use a towel instead of clasping hands directly?
Many people lack the shoulder mobility to clasp their hands behind their back, which is the baseline Apley scratch test position. The towel bridges the gap so you can still achieve a productive stretch without straining to force the hands together prematurely.
Who benefits most from this stretch?
Anyone with limited shoulder mobility benefits, including desk workers with rounded posture, overhead athletes such as swimmers and tennis players, and older adults working to maintain functional shoulder range of motion. It is also used in rehabilitation after shoulder injuries to gently restore mobility.
How do I progress this stretch over time?
As your mobility improves, you can gradually walk your hands closer together along the towel. When your hands can comfortably meet and overlap, you can attempt the unassisted Apley scratch stretch without the towel. Adding a brief gentle traction pull (the top hand pulling up, bottom hand pulling down) can also deepen the stretch once you are comfortable with the basic hold.
