How to do it

1. Start in a push-up position, hands under your shoulders and your body in a straight line from head to heels.
2. Lower your chest to the floor and press back up, then lift one hand off the floor and tap it to your opposite shoulder before placing it back down.
3. Push-up, tap, push-up, tap - alternating the tapping hand each rep.
4. The tap is where the real work hides: for that moment on one arm, your whole body has to fight the urge to tip sideways.
