Pictorial description of which muscles are used in which exercise. Perfect for trainees or newer teachers and only $12.99 at your local Post Office, of all places.
One of the best instructional Pilates books I have read. Christine has put a lot of thought into the flow of the book, including body geometry tips, description of anchor points and illegal movement alerts. The descriptions are simple, and clear and the page layout is such that your eye is drawn to the important pieces of information.
