How to do it

Setup

  2. Engage your core and keep your chest lifted with a soft bend in your knees.

Movement

  1. Jump lightly off the balls of your feet, spreading your legs out wider than shoulder-width.
  2. Simultaneously sweep your arms out to the sides and overhead until your hands meet or nearly touch above your head.
  3. Immediately jump again to return your feet together while bringing your arms back down to your sides.
  4. Land softly on the balls of your feet and transition smoothly into the next repetition.

Breathing

Cues
