The behind head chest stretch is an assisted static stretch that opens the chest, lengthening the pectoralis major across both its upper clavicular fibers and its lower sternal fibers. With your hands clasped behind your head and a partner gently drawing your elbows back, it stretches the chest and is useful for counteracting rounded, hunched posture after pressing work or long hours at a desk.
How to do the Behind Head Chest Stretch
- 1Sit or stand tall with your spine long, shoulders relaxed, and core gently braced, with your partner positioned behind you.
- 2Clasp your hands or interlace your fingers behind your head, resting your palms against the back of your skull with your elbows pointing out to the sides.
- 3Keep your chin level and your neck neutral so the stretch stays in your chest, not your neck.
- 4Have your partner take hold of your elbows and slowly draw them back and out until you feel a comfortable stretch across the front of your chest.
- 5Lift your chest slightly and let your shoulder blades draw together to deepen the opening through the pectorals.
- 6Hold the stretch for 20–30 seconds, breathing slowly and evenly while your partner maintains light, steady pressure.
- 7Signal your partner to ease off gradually, then bring your elbows forward and lower your arms to relax.
- 8Repeat for 2–3 holds, easing a little deeper only as the muscle relaxes.
Form tips
- Communicate with your partner throughout so they apply only as much range as feels comfortable and stop at the first sign of a mild stretch.
- Breathe out as your partner increases the range; exhaling helps the chest relax and lengthen rather than tense up.
- Stretch to the point of mild tension, not pain — a static stretch should feel like a gentle lengthening, never sharp.
- Keep your neck neutral and your shoulders pulled down away from your ears so the work stays in the chest.
- Hold the position still rather than letting your partner bounce or pulse your arms, giving the pectoral fibers time to relax and lengthen.
Common mistakes
- Letting your partner draw the elbows back too far or too fast, which triggers a protective reflex that tightens the muscle and can strain the chest.
- Bouncing or pulsing the elbows back instead of holding steady, which prevents the pectoral fibers from relaxing into the stretch.
- Pulling the head down with the clasped hands, which loads the neck and cervical spine instead of stretching the chest.
- Holding your breath, which increases tension and prevents the chest from fully opening into the stretch.
- Shrugging the shoulders up toward the ears, which shifts tension to the neck and traps rather than opening the chest.
Frequently asked questions
What muscles does the behind head chest stretch work?
It stretches the chest — the pectoralis major, including both the upper clavicular head and the lower sternal head — as your partner draws your elbows back and opens the front of the torso.
How long should I hold the behind head chest stretch?
Hold each repetition for 20–30 seconds while breathing steadily, then repeat for 2–3 holds. Static stretches are most effective when held long enough for the muscle to relax.
Is the behind head chest stretch good for beginners?
Yes. It is a gentle, low-risk assisted stretch with no load, making it well suited to beginners as long as your partner moves slowly and you stop at a mild, comfortable stretch.
When should I do the behind head chest stretch?
It works well as a cool-down after chest or pushing workouts and as a posture break during long periods of sitting, when the chest tends to tighten and the shoulders round forward.
Where should I feel the behind head chest stretch?
You should feel a mild stretch across the front of the chest. If you feel sharp pain or a pinch in the shoulder joint, have your partner reduce the range right away.
