Lay on your front with a swiss ball behind you. Resting on your forearms, lift your feet onto the swiss ball to come into a plank position. Keeping even weight through your forearms, lift your hips into a pike by drawing the ball in towards you. Keep your core engaged and knees straight, before straightening your legs to return to the start.
