Query: Excellent reference for beginners through advanced

This is an excellent reference book. It covers all the basic hand/arm and foot/leg techniques. The stop action photos are helpful in showing the complete movement of a technique. The text is written very clearly in easy to understand terms. That's one of the reasons I always recommend this book to my beginning adult (Shotokan)karate students. My students always tell me that they find it very helpful, especially when practicing at home and needing a reference to guide them. This is a "must have" book for any level karate student.
