How to do it

1. Start in a forearm plank with your elbows under your shoulders and your body low.
2. Sweep one knee out and up along your side, drawing it toward your elbow - your hip rolling open as the knee travels - then extend the leg back and sweep with the other knee.
3. Stay low to the floor throughout, like a crawl performed on the spot: the knee hugs the ground on its way up, and your shoulders stay steady over your elbows.
