Setup
- Stand with feet shoulder-width apart and a neutral spine.
- Hold a long towel with a very wide overhand grip, significantly wider than shoulder-width.
- Start with the towel resting against your front thighs and your arms fully extended.
How to do it
- Inhale and slowly raise your arms overhead, keeping your elbows completely locked.
- Exhale as you continue the rotation behind your head until the towel touches your lower back or glutes.
- Inhale and reverse the movement, bringing the towel back over your head to the starting position.
- Maintain a slow, controlled tempo, ensuring both arms move simultaneously without bending.
Form checklist
- Keep your elbows locked and arms straight throughout the entire movement.
- Brace your core to prevent your lower back from arching as your arms go overhead.
- Keep your shoulders depressed (down) and avoid shrugging toward your ears.
- Maintain constant outward tension on the towel by pulling your hands away from each other.
Pro tips
- Actively pull the towel outward as if trying to rip it in half to better engage the posterior deltoids and stabilize the scapulae.
- Spend extra time moving slowly through the 'sticking point' at the very top to maximize the stretch in the pec minor.
Make it harder
- Gradually move your hands closer together on the towel to increase the mobility requirement.
- Perform the exercise while kneeling or sitting to eliminate any compensation from the hips or legs.
