The Expression of the Human Body is a good refrence book for training. It has alot of diagrams drawn by Lee himself. It explains Lees ideals of training and conditioning the body. It has alot of info from diet, to just working with a heavy bad to improve punching and kicks. I like it. Like every book, there will be parts you can take from it, and some you'll ignore. It is an interesting book, and jam packed with info. Like i said, it is a good refrence material for conditioning and training. Im sorry, i have not read the others.
