What it stretches
Holding your arm back against the frame while your body moves forward stretches the large chest muscle, the smaller muscle beneath it, and the front of the shoulder. These shorten when you spend a lot of time with your arms in front of you and your shoulders rounded.
Changing the height of your elbow changes which part of the chest you feel most. At shoulder height is the usual starting point; a little higher reaches the lower part of the chest.
- Main muscles
- Pectoralis majorPectoralis minorFront deltoid
- Where you feel it
- Across the chest and the front of the shoulder
How often to do it
Once or twice a day is plenty, and it works well as a desk break. It takes under two minutes for both sides.
Pair it with shoulder rolls to loosen the shoulders first, then open the chest.
- Every dayOnce or twice
- 30 secondsEach arm
- Desk breaksAfter long screen sessions
- In the app
- Posture Reset routine, and free to try in the stretch library
Common mistakes
Elbow too high
Raising the elbow well above the shoulder can pinch the front of the joint. Start at shoulder height.
Arching your back
Don't push your ribs forward to go deeper. Keep your stomach lightly braced and lean from the ankles.
Shrugging
Keep the shoulder of the stretching arm down and away from your ear.
Lunging too far
A small step is enough. A big lunge puts strain on the shoulder rather than stretching the chest.
Make it easier or harder
Easier
- Take a smaller step, or none at all.
- Place your hand on the frame lower down, with a straighter arm.
- Do one arm at a time and keep the stretch light.
Harder
- Put both forearms on either side of the doorway and lean through with both at once.
- Try the elbow a little higher or lower to find other parts of the chest.
- Follow it with the Posture Reset routine in the app.
Look after yourselfThis guide is for general fitness and flexibility, not medical advice. Keep the stretch comfortable, and stop if you feel pain in the shoulder, or tingling or numbness down your arm. If you have had a shoulder dislocation or injury, check with a health professional first.
