Forget those expensive ab infomercial gadgets -- all you need for toned abs and a strong, defined, flexible body is an exercise ball and Get on the Ball for Great Abs. In her first book, Get on the Ball, fitness expert Lisa Westlake showed just how fun and easy it is to get in shape using the wobbly exercise ball, as stabilizing one's body on it requires using new skills to "wake up" your muscles. Now, she offers more than 60 all-new, easy-to-follow exercises, including some featuring weights, specifically geared toward strengthening the core, abdominal and obliques muscles to perfect your waistline. Each exercise is illustrated with a black and white photo and the workouts progress from easy to higher degrees of difficulty, making this ideal for beginners, avid gym-goers, and top athletes alike. For anyone who wants a slimmer waistline and more stable, defined abs, Get on the Ball for Great Abs will help readers get the best from their exercise ball.
