STARTING POSITION:
Get in to a face down position. Rest your forehead on your forearms. Extend your legs straight out behind you. The ankle of the leg that is going to do the exercise should be on top of the other ankle.
MOVEMENT:
Fully bend the knee that is going to do the exercise while you exhale. To help it, push the leg with the other leg from the ankle. Return to the starting position in a smooth movement.
TIPS: To increase the level of the exercise, don't help yourself with the other ankle when you return to the starting position.
