Brazilian Jiu-Jitsu promotes the concept that a smaller, weaker person can successfully defend themselves or another against a bigger, stronger, heavier assailant by using proper technique, leverage, and most notably, taking the fight to the ground, and then applying joint locks and chokeholds to defeat the opponent. 

BJJ is also an integral element of Mixed Martial Arts (MMA) training where all elements of Martial Arts are combined and practitioners compete against one another using elements of striking, submission and grappling to defeat their opponent, this can primarily be noted or seen on global MMA franchise the Ultimate Fighting Championship (UFC).
