Doorway chest stretch for rounded shoulders
Hours at a desk can leave the front of your chest feeling tight and your shoulders rolled forward. A doorway stretch gently opens the chest using nothing but a door frame.
General information, not medical advice. Move gently and stop if anything hurts.
How to do it


- Stand in a doorway with your forearms on the frame, elbows bent about 90 degrees.
- Step one foot forward and lean gently until you feel a stretch across your chest.
- Keep your ribs down and breathe slowly.
Dose: Hold for 30 seconds.
Tip: Stop if you feel tingling in your arms. Lean less.
Common mistakes
- Leaning too far. You want a mild stretch across the chest, not a pull in the front of the shoulder.
- Letting your ribs flare and your lower back arch. Keep your ribs down.
- Holding your breath. Breathe slowly through the hold.
- Pushing through tingling in the arms. Ease off and stop if it stays.
Pair it with a shoulder blade squeeze. Stretching the chest and waking up the upper back works well together.
When to stop and see a professional
Stop and speak to a doctor or physiotherapist if you notice:
- numbness, tingling or weakness in an arm, hand, leg or foot
- pain that spreads (radiates) down an arm or leg
- pain that started after an accident, fall or other injury
- loss of bladder or bowel control, or numbness between your legs (seek emergency care)
- pain that keeps getting worse, wakes you at night, or comes with fever or unexplained weight loss
