Your back should be straight and you should look forward not down. This is the starting position. Slowly pull your knees straight in towards your chest, rolling the fitness ball in smoothly. Exhale during this movement. Keep looking forward and your back straight. Slowly extend your legs to the starting position. Inhale during this movement. Keep looking forward and your back straight. Repeat the movement for the required number of repetitions.
