How to do it

1. Squat down until your thighs are close to parallel with the floor, extend your arms straight out in front of you for balance, and stay there.
2. That's the whole exercise - and that's exactly why it's hard.
3. Keep your weight in your heels, your chest up and your back straight, and hold the position while your legs slowly begin to negotiate.
4. Time under tension does all the work here: no reps, no movement, no escape.
