Query: I agree with J. Pena's review

This book was NOT recommended for my teacher training, I bought it to supplement because the one that was assigned wasn't helping me at all. I had not had biology since college 25 years ago, and my knowledge was pretty sketch. If you are well grounded in anatomy this would be a nice reference. However I do not believe anyone could LEARN anatomy from this book. It's just page after page of pictures with Latin names next to the muscles and bones and such. My eyes glazed over. I had trouble memorizing the stuff.There is a better book I like that shows the body in actual yoga poses - called the Key muscles of yoga. It is not an easy read either, but it was more useful to me in the specific task of teaching yoga.
