Unlike other books based on Joseph Pilates's teachings, this one illustrates the core matwork movements exactly as Pilates intended them to be performed. The book begins with 15 two-page spreads that answer readers' questions about Pilates and the core principles of the program. The bulk of the book is then devoted to the exercises, with over 200 photos. A lay-flat binding makes it easy to learn each movement by following the photographic sequences and explanatory captions.
