Brazilian Jiu-Jitsu practitioners use ultimate ground fighting.
They share a wide range of armlocks (shoulder, elbow, wrist), of leg locks (knee, ankle, foot), of neck locks and of chokes. Brazilian Jiu-Jitsu represents an expertise in ground fighting, with the rediscovery of new specific positions such as the guard (in which, back to the ground, you surround the opponent’s waist with your legs) that enables you to defend against submission techniques and to be able to exit.

Brazilian Jiu-Jitsu and its vale-tudo application (free fight in Portuguese) showed particularly effective in 1993 when The Ultimate Fighting Championship (UFC) was created, then won by Royce Gracie, or later by Rickson Gracie, considered by many as the best fighter who’s ever lived, for, as the legend says, he’s never been defeated after more than 400 free fights.
