How to do it

  1. 1Shoulders and upper back opening as the arms sweep down
  2. 2A light stretch across the chest at the bottom
  3. 3Smooth, rhythmic motion that loosens the shoulders

Common mistakes

  • Arching the lower back as the arms go overhead
  • Letting the towel go slack and losing tension
  • Jerking the arms instead of moving with control
