Brazilian Jiu-Jitsu (BJJ) was the first martial art to dominate the Ultimate Fighting Championship (UFC) and it remains one of the most effective forms of self-defence and an essential component of modern MMA. A grappling-centric art, the goal of BJJ is to force your opponent into submission with joint locks and strangle. Emphasing on technique and leverage, BJJ was designed to allow a smaller person defeat a stronger opponent with skills. BJJ is often described as a game of "human chess" due to it's depth and complexity.
