Brazilian Jiu-Jitsu emphasizes live training, giving students the chance to develop their skills in real time. In the Jiu-Jitsu community, sparring is called “rolling” and is a game played with the goal of submitting the other with a technical submission hold. We use joint locks and choke holds to leave the other player no other option but to surrender or “tap out”. This is done in a safe manner so that we can continue to train daily without injury.
