How to do it

Start standing with feet together and arms down. Jump your feet out wide while raising your arms overhead like a jumping jack, then jump back to the start. Stay light and bouncy on the balls of your feet.

  1. 1Feel your calves spring you off the floor each rep
  2. 2Keep a light, quick bounce and steady rhythm
  3. 3Land soft with a small knee bend

Common mistakes

  • Don't land heavy or stomp your feet
  • Avoid jumping excessively high; keep it quick
  • Don't hold your breath; stay relaxed
