Brazilian Jiu Jitsu is a fusion of Japanese Judo/Jiu Jitsu and Western Wrestling created in the 1920’s by the Gracie family in Brazil.
BJJ revolves around the concept that a smaller, weaker person can successfully defend themselves against a bigger, stronger, heavier opponent by using leverage and weight distribution, taking the fight to the ground and using a number of holds and submissions to defeat them.
Brazilian Jiu Jitsu is traditionally practised in a gi (kimono).
