I'm a yoga teacher and was looking for something to delve deeply into the anatomy of the postures. This book describes the anatomy beautifully and goes into detail. It's detailed but clear enough for a layperson like me to understand. I also found little Youtube links by the same author which give snippets about yoga anatomy. I'd highly recommend this book to yoga teacher and practitioners who want to look beneath the surface to see what is happening while moveing into and out of the yoga postures.
