I really like this Judo book.
It is not a 'fully comprehensive' book that shows you every technique of Judo, but it does show the most effective techniques, street-fighting techniques, weapons defenses; it teaches you about proper dieting, muscle conditioning, extensive balance and strength drills and games, the history of Judo and so on.
The greatest part of the book though, is it's extensive lesson on 'kuzushi': the art of breaking the opponent's balance in order to be able to execute a throw upon him/her. This section of the book is the best I have ever seen anywhere! It has many pages, one after another, showing an entry throw set-up, and around this throw are depicted eight backup throws that will work if the first one fails - which it almost always will, since the opponent is not unbalanced yet. These eight backup throws all make use of the position you have gotten into and the unbalancing you have executed upon the opponent as a result of attempting the first throw. This is REALLY USEFUL for all Judoka! You can use this knowledge during every competitive practice session (randori) at your club!
This is also a really cool book to have since it is written by the leader of the world's largest nation - President Vladimir Putin of Russia! This shows how Judo can help you achieve any goal you want to attain!
