Yoga Anatomy is a book that gives the reader a look inside the human body as it is put in various yoga positions.
Chapter 1 covers the dynamics of breathing and actually covers some breathing physiology as well. Chapter 2 talks about the spine and gives some pretty detailed spinal information. Chapter 3 is short and covers the asanas.
The rest of the book, Chapters 4 through 9, make up the "meat" of the book and contains most of the anatomy information most readers probably bought the book for- what muscles are used in what poses. The way the book gives you the information is quite handy- it has a section on standing poses, sitting poses, kneeling poses, on-your-stomach poses, on-your-back poses, and arm supported poses. Sooo, all you have to do is pick a position/pose, and there you'll find pictures of what muscles are involved (and let me say, they show you some great angles of the poses to make sure the reader can see ALL the muscles that are involved). In addition to learing what muscles are involved, the book also tells you what joint actions are involved, as well as what body parts are working AND which ones are lengthening- neat!
A great reference book, its simply perfect for the yoga enthusiast that has become acquainted over time with muscles they never knew they had- but will now after reading this book! Also recommend The 5-Minute Plantar Fasciitis Solution if plantar fasciitis pain keeps you from doing your yoga.
