Muscles worked
Setup
- Stand with your feet shoulder-width apart and a slight bend in your knees.
- Extend your arms straight out to your sides at shoulder height, palms facing forward.
- Engage your core and maintain a tall, upright posture with your gaze forward.
How to do it
- Swing your arms across the midline of your body at shoulder height, alternating which arm crosses over the top, then return to the starting position.
- Repeat the movement, but cross your arms at a high angle (above head height) before returning to the start.
- Perform the final cross at a low angle (waist height), exhaling on every cross and inhaling as you open your chest.
- Move through these three positions (middle, high, low) in a fluid, controlled rhythm.
Form checklist
- Keep your shoulders pulled down and away from your ears.
- Avoid arching your lower back as your arms swing back.
- Maintain a slight, soft bend in the elbows throughout the movement.
- Ensure the movement comes from the shoulder joint, not by twisting the torso.
Pro tips
- Focus on a deep stretch in the chest during the 'open' phase and a hard squeeze of the pecs during the 'cross' phase.
- Maintain constant tension by imagining you are moving your arms through thick honey or water.
Make it harder
- Hold small weighted plates or light dumbbells to increase the demand on the deltoids.
- Perform the movement while standing on one leg to challenge your core stability and balance.
