The book, "Modern Pilates, the step by step, at home guide to a stronger body", is Penny Latey's first book concerning the art of the Pilates method. It is intended as a reference for Pilates practitioners who wish to use the Method at home.

The book explains in great detail the history of Pilates and its founder, Joseph Pilates. It discusses the variations on the form that Penny Latey implements at her studio. It gives clear and easy to understand insights into the human body and its mechanical operation, and thereby allows one to more clearly understand how Pilates works.

The book also discusses the methods as initially developed by Joseph Pilates, and compares it with current methods as used in the Modern Pilates Studio. It also compares and links Pilates theory with practical methods.

Each and every section of the book includes diagrams and photos, clearly demonstrating and highlighting relevant points and exercises to practice.

Modern Pilates is an essential book for students and teachers of Pilates at any level. It provides easy to understand information on what Pilates is and how it works, and also allows the reader to improve their own health and fitness from the comfort of their own home. The book, due to its inherently easy to understand layout, is also ideal for those who are curious about Pilates, but have had little or no previous contact with the Method.
