High knees – how to do it right

Run on the spot, knees up.

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. Run on the spot, knees to hip height.
  2. Land on the balls of your feet.
  3. Swing your arms.
  4. Quieter: lift your knees slowly without jumping.

How long?

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

If something niggles

Kids asleep or neighbours below? Knee niggling? Then do Side lunges 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.

In BLOX
