This exercise is called the oblique crunch. Sit in a upright position on the exercise ball, but keep your feet flat on the floor. Now slowly walk your feet forward, so that the ball is positioned on lower to mid back area. Support your neck with your hands and slowly lift your torso off the ball and twist to the right side first. Slowly lower your torso, to repeat the same on the left side. While you do this exercise, you will have to make sure, that your head and back are in a neutral position.
