Isacowitz and Clippinger (functional anatomy, California State U., Long Beach) draw on 60-plus combined years of experience in the study, performance, practice, and teaching of Pilates to create a text for all levels of Pilates professionals and enthusiasts, which is also suitable for the many different approaches to Pilates. Based on the original matwork and publications of Joseph Pilates, the opening chapters explain the six key principles of Pilates; the anatomical aspects of spine, core, and body alignment; and muscles and movement analysis in relation to matwork. Subsequent chapters provide detailed descriptions, step-by-step instruction, and clear anatomical illustrations for 45 exercises designed to stretch, strengthen, and finely coordinate specific muscles to tone the body, stabilize the core, improve balance, and increase flexibility.
