How to do it

1. Stand with your feet together and your arms relaxed at your sides.
2. Step one foot out to the side, then step it back in, and repeat with the other leg.
3. Your arms stay down the whole time - all the movement comes from the legs.
4. It's half the jack: the footwork without the arm swing or the jump, which makes it the gentlest entry point into the jacks family and an easy way to get the blood moving.
