I must say that I am utterly frustrated with this book. I do not have an antomy in background, but I am a yoga enthusiast. I find that body parts are mentioned throughout assuming that the reader knows where they are whilst no previous reference has been made to them. A simple picture would really help showing the major muscles, bones joints etc. I have re-read the first few sections twice now and I am till utterly confused. I honestly spend more time googling the terms used in the book that I do just getting on with the book. It is a most frustrating read. Does not even have an index!
