Stability balls are a pretty fun tool to change up your workouts and challenge yourself to new levels of fitness. It's sort of funny how such a simple piece of equipment has so many uses and can do everything from rehabilitate the elderly, to enhance the conditioning of an MMA fighter. The main function that the ball is designed for is strengthening your core and abdominal wall. Now if you're like most people, you probably feel more than a little stupid performing the basic exercises demonstrated on the poster located on your gym wall! Well have no fear!! I've put together a short video demonstrating a few of my favourite stability ball exercises along with a few others that don't include the ball. Each one will challenge your core/abdominal strength in unique and functional ways. If at first you have trouble performing these exercises, there are plenty of progressions and body weight exercises to help you build the strength to perform them, for more info click here!
