Those who've enjoyed professional trainer and author Craig's previous books (Pilates on the Ball
; Abs on the Ball
) will want to check out her latest work, which focuses on working out on an exercise ball while using free weights or resistance bands. Exercising on the ball, the author explains, develops strength and balance simultaneously. She says it's particularly useful for older adults, sedentary people with weak core muscles, postnatal women, elite athletes and postoperative patients, teens and children. Craig advocates using weights in conjunction with the instability of the ball, because when you work on a mobile surface, gravity and your own body weight make the exercise more challenging. Each chapter begins with an anecdote from one of Craig's clients, followed by a clear explanation of Pilates-based strength building exercises (and accompanying photos) that target deep as well as superficial muscles. Concluding sections discuss such topics as diet, choosing the right ball and dealing with common ailments. Craig defines the purpose of each exercise and offers explicit "watch points" to make readers aware of problems that may arise while they're doing the exercises. General readers and instructors alike will find Craig's instructions for combining the ball with strength-building techniques adaptable to all levels and ages. Photos. (May)
