How to do it: Stand on your right leg with your left foot placed behind you, hands clasped behind your head. Keeping your back straight and abs tight, bend your right knee and hinge forward from your hips, lifting your left leg off the floor as you lean forward. Go as far forward as you can, trying to make a ‘T’ shape with your body. Return to start position. That's one rep. Repeat as many times in a row as you can for 30 seconds and then switch legs.
Tip: If balancing with your back leg lifted is too challenging to start, keep your back foot lightly tapped on the ground as you hinge forward.
