Jiu Jitsu is a martial art translated as “gentle art” or “art of non-resistance”. In practical terms this means that, rather than resisting force with force, one yields to force allowing an opponent’s strength to be used against him. In this way, efficient technique is used in an intelligent fashion to overcome raw strength and aggression. There is no striking in BJJ. Brazilian Jiu Jitsu focuses primarily on controlling distance, space and utilizing position and leverage to control opponents which is done, for the most part, on the ground.
