Edition 4.1 - Updated 2025 Jiu jitsu is an unarmed form of combat first used by the samurai warriors of ancient Japan. It's an all-round martial art that uses striking, blocking, grappling, locking, throwing, ground, submission and weapons techniques. The emphasis is on technique over power and strength by using the opponent's force against themselves. This book is not intended to be a ‘how to’ manual for learning jiu jitsu, instead it picks up on all those areas of jiu jitsu that can be learned and researched ‘off the mat’ and outside of the dōjō. For those students wanting to achieve higher grades in jiu jitsu this book will supplement their physical training with a wider theoretical knowledge.
