Stand up straight with your legs wide apart.
Turn your toes out to approximately 45 degrees.
Cross your arms over your chest.
Keeping your abdominals tightened, push your hips backwards and bend your legs, sinking your hips down between your feet.
Ensure your knees travel out sideways over your toes as you do this.
Stop when your thighs are at a horizontal position.
Keep your back straight and your gaze directly ahead.
Push through one foot to straighten this leg, moving your weight onto the other side.
You should feel a stretch down the inside of the straight thigh.
Move back to the central position and straighten your other leg.
Repeat this movement.
