Cross jacks – how to do it right
Jump, crossing legs and arms in front in turn.
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
- Jump: legs and arms out wide.
- Then cross legs and arms in front, switching which is in front.
- Land softly on bent knees, tight core.
- Quieter: no jump, tap one foot across in front.
How long?
In BLOX: 30 seconds on, 10 seconds rest, three rounds.
If something niggles
Kids asleep or neighbours below? Knee niggling? Then do Low-impact jacks 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.
