How to do it

1. Lie face-down on a bench with your legs hanging off the edge.
2. Bend your hips so your thighs are vertical, bending your knees at the same time so your shins stay horizontal.
3. Straighten out your legs so they are not bent and your toes are pointing backwards horizontally.
4. Return to the original position, and repeat.
