How to do it

Stand tall with your feet shoulder-width apart and extend your arms out to your sides at shoulder height. Gently swing your arms forward, crossing them in front of your chest, then open them back out wide, squeezing your shoulder blades together to stretch your chest. Continue this forward and back motion in a smooth, controlled manner for the specified reps. Keep your posture upright and avoid bouncing.

  1. 1Feel the stretch across your chest and shoulders as you open your arms wide
  2. 2Engage your scapular stabilizers to control the swinging motion
  3. 3Breathe into the stretch and gradually increase the range as you warm up

Common mistakes

  • Avoid snapping or jerking your arms; keep the movement smooth
  • Don't arch your back excessively; maintain a neutral spine
  • Avoid letting your shoulders creep up toward your ears
