Brazilian Jiu Jitsu (BJJ) is probably the world's fastest growing sport. It first exploded onto the world scene in the early nineties when the Gracie family defeated all challengers from other Martial Arts and combat sport styles such as Kickboxing, Boxing, Judo, Traditional Japanese Ju Jitsu (Jujitsu/Jujutsu), Taekwondo, Hapkido, Karate, Wrestling, and Kung Fu, in no rules challenge matches.
This most in-demand martial arts style has turned the martial arts upside down by emphasizing real-life situations and results over the dramatic kicks and throws of formal competition. The secret? In real fights, the combatants usually clinch and fall to the ground. It is there that the fight is decided. Punches don't matter. Fancy moves don't matter. Just get your opponent in a choke or lock and it is over.
This is the genius of Brazilian Jiu-Jitsu.
