How to do it

1. Stand with your feet wide and sink into a squat with your arms at your sides.
2. Straighten your legs to come up to standing and sweep your arms up overhead as you rise, then sink back into the squat as your arms drop back down.
3. It's a jumping jack with the jump taken out - the legs do a squat, the arms do a jack, and the two meet at the top of every rep.
