Standing Chest Cross Stretch

Setup
- Stand with feet hip-width apart and maintain an upright, neutral posture.
- Extend both arms out to your sides at shoulder height, palms facing forward.
- Engage your core to stabilize your spine and prevent your lower back from arching during the movement.
How to do it
- Inhale and pull your arms back horizontally to feel a deep stretch across your chest and the front of your shoulders.
- Exhale as you swing your arms across the front of your body, crossing one arm over the other in a 'hugging' motion.
- Inhale as you swing your arms back to the wide, open starting position.
- Repeat the movement at a controlled, rhythmic pace, alternating which arm is on top for every repetition.
Form checklist
- Keep your arms at shoulder height throughout the entire range of motion.
- Maintain a proud chest and avoid shrugging your shoulders toward your ears.
- Keep your neck neutral and your gaze fixed straight ahead.
- Control the movement to avoid using excessive momentum that could strain the shoulder joint.
Pro tips
- Focus on actively squeezing your shoulder blades together during the 'open' phase to maximize the stretch on the pectoral muscles.
- Keep your palms facing forward or slightly upward to encourage external rotation of the shoulder, which safely opens the chest cavity.
Make it harder
- Add a two-second static hold at the end of the 'open' phase to deepen the stretch on the chest fibers.
- Perform the stretch while standing on one leg to challenge your core stability and balance simultaneously.
