This book is just great. It's very technical at some points (I don't know very many anatomy terms). But the author explains everything very simply and with diagrams. If I wasn't taking martial arts though, I wouldn't know what he meant by "knife hand" or "hammer fist". He does not explain (from what I could tell) how to preform these strikes. This is not a book on how to take someone out with a flick of the finger. It's for the martial artist to know where to strike and what damage you could possibly do. This is very important to know in a real life or death situation. Very empowering.
