Instructions
Position yourself on all fours with your torso on a swiss ball and hands and feet on the floor. Stretch your legs back and keep your hands under your shoulders.
Engage your abs and slowly walk your hands forward until your feet lift off the floor. Carry on walking out until your quads or knees rest on the ball in a plank position.
Slowly bend your knees in towards your chest allowing the ball to roll forward. Tuck your knees under your torso as your hips lift towards the ceiling.
Slowly straighten your legs and roll the ball out to the starting position.
