Looking to expand my knowledge of physiology to improve my skills as a Personal Trainer, I purchased Dr. Muscolino's excellent book on Kinesiology. I liked it so well, I purchased this book, too.I found his writing style to be perfect for me. He starts very simply and gradually adds complexity, so that you learn without being overwhelmed. The formatting is consistent throughout the book so that you can easily find the information you're looking for when using it as a reference.No one mentioned the CD, but I found it very helpful as well.
