Muscles worked

Primary

  • Deltoids
  • Pectorals

Secondary

  • Abs
  • Serratus anterior

Equipment

  • Body weight

Setup

  1. Stand with your feet shoulder-width apart and a slight bend in your knees.
  2. Extend your arms straight out to your sides at shoulder height, palms facing forward.
  3. Engage your core and maintain a tall, upright posture with your gaze forward.

How to do it

  1. 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.
  2. Repeat the movement, but cross your arms at a high angle (above head height) before returning to the start.
  3. Perform the final cross at a low angle (waist height), exhaling on every cross and inhaling as you open your chest.
  4. 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.
