Plank jacks – how to do it right

In a plank, jump your feet apart and back together.

This is how Stickfreed, our glowing stick figure, shows you the exercise on your TV – here the start, middle and end position. In the app he turns slowly so you can see everything.

How to do it

  1. High plank, hands under your shoulders.
  2. Jump your feet apart and back together.
  3. Hips stay still and in line.
  4. Quieter: tap one foot out to the side in turn.

How long?

In BLOX: 30 seconds on, 10 seconds rest, three rounds.

If something niggles

Kids asleep or neighbours below? Don’t fancy the floor? Shoulder niggling? Then do Mountain climbers instead – BLOX swaps it automatically if you mention it at the start. Stop if it hurts; if you have complaints or pre-existing conditions, check with a doctor or physio first.
