Hi, I'm CarolAnn with cyberworkouts.com, and I'm going to show you stomach exercises using an exercise ball. So, come on down to your ball, and you want to have your lower back pressing right into that ball nice and supported. Take your hands behind your head and keep your elbows wide. And you are just going to simply come up to a crunch and then come back. What's really great about the exercise ball is that you can use full range of motion, really open up, and then curl up and crunch. As you are coming up, really exhale through the mouth, forcefully contracting those abdominal muscles. And you can perform about 20 to 25 reps. To work your obliques, just simply go at a diagonal angle. So, you are going to really target those obliques. Perform about 20 reps in one direction and go then to the other side, 20 reps. Making sure you get both sides. You can even alternate if you wanted to, alternate side to side, hitting those obliques. Another oblique exercise is to lift the shoulder blades up off the ball. One hand remains behind the head, and simply lean to the side. So, this is a great lateral flexion of the spine incorporating those obliques. And you can perform about 20 to 25 reps on each side. Make sure you are exhaling every time you bend. And to really burn out those abs come on up, start at the center, and make a big circle trying to lift the middle of your back up off the ball. Perform about 20 reps in one direction, and then switch, go in the other direction. And then rest. When you are finished, simply come up to a seated position. Those are some really great stomach exercises that you can perform on the exercise ball. I'm CarolAnn for cyberworkouts.com.
