Brazilian jiu-jitsu (Bjj) is derived from Japanese jiu-jitsu and judo, but has for decades been further developed by the Gracie family from Brazil. BJJ is a grappling-style which means that you do not use punches or kicks, but instead focus on joint locks and strangulations that incapacitate your opponent. The basic idea is to bring down your opponent to the ground, control him/her to stay there and with the help of joint locks and strangulations compel them to give up. Bjj is usually emphasized as the martial art where smaller opponents have the greatest opportunity to overpower larger and stronger ones. The reason for this is that technique always comes before physical characteristics such as size and strength. By focusing on technique and concentrating on the keeping the fight mainly on the ground does give the person with the smaller body size an advantage. This is the magic that makes Bjj the martial art that is suitable for all boys and girls, small and large, young and old!
