This book contains more than 150 exercises with pictures and is divided into six categories: warm-up, flexibility, balance, lower limbs, upper body and abs. The author explains the principles that apply to the selection and use of the exercise ball, and the rules that apply to reps, series, resting time and selecting the exercises. Two high quality pictures and a brief description explain each exercise. The laminated cover and spiral binding make this book easy to use and to carry. 2003
