This quickie core workout uses the unstable surface of the ball to train the muscles in your pelvis, lower back, butt, hips and abdomen to work in harmony. This leads to better balance and stability, whether in sports or in daily activities. You can increase the intensity of your workout on the ball and place increased stress on your core just by adjusting your position. The effort to remain balanced engages additional muscles. For example while doing crunches, the closer your feet are to the ball, and the less of your upper back is on the ball, the harder the exercise will be. As you master these exercises, move your body around on the ball so that it supports less of your body to increase the challenge.
