Brazilian Jiu-Jitsu (BJJ) is widely considered to be the most effective combat art on the planet.
Made famous by the Gracie family, this ground focused fighting system proved devastating in early no-holds-barred fighting tournaments. (See Royce Gracie in UFC 1!)
The BJJ delivery system demonstrates better than any other how a smaller, weaker person can successfully defend themselves against a bigger, stronger, heavier opponent by using technique, leverage, and most notably, taking the fight to the ground, and then applying joint locks and chokeholds to defeat the opponent.
BJJ training can be used for sport grappling tournaments, mixed martial arts, and self-defence.
