Meredith Nelson: Hi, I am Meredith Nelson with Prime Time Fitness on Sullivans Island in South Carolina. Today we are going to teach you how to exercise with a Stability Ball. The Stability Ball is great to incorporate into your workouts, because it helps you develop and enhance your core strength and stability. First, I would like to give you a brief introduction to the Stability Ball. Stability Balls were first used in rehabilitation settings by physical therapists. Now, however you can find them in gyms and fitness centers and hospitals and even in offices and schools. You can find a Stability Ball in just about any major department store or a sporting goods store. You may also wonder just how to choose the ball that's the right size for you.
Balls come in several different diameters; 55, 65, 75 and 85 centimeters in diameter and to determine which of this is right for you, once the ball is inflated your knees and your hips should be in level with one another or your hips slightly higher than your knees. If your hips drop below your knees, you may need a ball, a little bit bigger. You also need to be sure that your ball is inflated properly. If it's not inflated enough, your exercises probably won't be as challenging, because they will be easier to balance. So once your ball is fully inflated, have a seat on it, make sure that your hips either level with or above your knees and you are ready to go. Let's get started. I am going to begin by showing you some exercises for your abdominals.
