Horizontal Rotation on Exercise Ball

Not only is this an incredible core stabilization exercise, but it is an awesome exercise for the obliques (side abdominal muscles) as well. The trick to doing this movement properly is to keep your hips up so that your upper legs are parallel to the floor at all times. Also, be sure that just your shoulders are on the ball and not your lower back, and also that you rotate as far as possible to the left and to the right. The farther away you get from the mid-line of your body during each rotation, the more you will get out of this exercise. You can use any kind of a bar, pole, or even a dumbbell or a medicine ball to vary your intensity level.
