How to do it

1. Start in a push-up position with your hands under your shoulders.
2. Drive one knee in toward your chest and, as it comes in, reach the opposite hand back to tap your foot - then plant the hand, extend the leg back, and repeat on the other side.
3. Every tap leaves you balanced on one hand and one foot for a moment, so keep your core braced and your hips low and steady through the switch.
