Brazilian Jiu-Jitsu (BJJ) is a martial art and combat sport based on ground fighting and submission holds. It focuses on the skill of taking an opponent to the ground, controlling one's opponent, gaining a dominant position, and using a number of techniques to force them into submission via joint locks or chokeholds.
Brazilian Jiu-Jitsu was first developed around 1920 by Brazilian brothers Carlos, Oswaldo, Gastão Jr., George, and Hélio Gracie, after Carlos was taught traditional Kodokan judo by a travelling Japanese judoka, Mitsuyo Maeda, in 1917.
BJJ revolves around the concept that a smaller, weaker person can successfully defend him/herself 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. BJJ training can be used for sport grappling and self-defence situations. Sparring, commonly referred to as "rolling" within the BJJ community, and live drilling plays a major role in training and the practitioner's development. BJJ can also be used as a method of promoting physical fitness, building character, and as a way of life.
