Setup
- Stand tall with your feet shoulder-width apart and a slight bend in your knees.
- Engage your core and maintain a neutral spine with your head facing forward.
- Extend your arms straight out to your sides at shoulder height, palms facing forward.
How to do it
- Swing both arms horizontally across the front of your chest in a rhythmic motion, crossing one arm over the other.
- Exhale as your arms cross in front, feeling a brief stretch in the rear deltoids and upper back.
- Inhale as you swing your arms back out to the starting position, pulling your shoulder blades together to stretch the pectorals.
- Continue the movement at a steady, controlled tempo, alternating which arm crosses on top for each repetition.
Form checklist
- Keep your arms parallel to the floor throughout the entire movement.
- Avoid arching your lower back as your arms swing open.
- Keep your shoulders depressed (down and away from your ears).
- Maintain a slight bend in the elbows to avoid joint locking.
- Use controlled momentum rather than aggressive, jerky movements.
Pro tips
- Focus on the 'squeeze' of the chest muscles as the arms cross to maximize pectoral activation.
- Think about reaching as far back as possible during the opening phase to maximize the dynamic stretch on the chest.
- Coordinate your breathing with the rhythm of the swing to help maintain a consistent tempo and core stability.
Make it harder
- Hold very light micro-weights or weighted gloves to add slight resistance to the swing.
- Increase the speed of the swings while maintaining a perfectly still torso to challenge core stability.
