Scientific Keys: The Key Muscles of Hatha Yoga Scientific Keys: The Key Muscles of Hatha Yoga by Ray Long

This is definitely a book to have as a hard copy. There is a LOT of great information about muscles, their placement in the body, antagonists and agonists, etc. It is a little overwhelming, and thus me saying that it would be good to have on hand to re-read often. For yoga teachers, this book is incredibly handy. 

I loved the introduction and opening chapters. They set the book up well. The illustrations are also a major plus. But again, so much to learn.

Four stars

This book came out November 1, 2009
