BJJ promotes the concept that a smaller, weaker person can successfully
defend against a bigger, stronger assailant by using proper technique, leverage, and most notably, taking the fight to the ground, and then applying joint-locksand chokeholds to defeat the opponent. BJJ training can be used for sport grappling tournaments (gi and no-gi) and mixed martial arts (MMA) competition or self-defense. Sparring (commonly referred to as "rolling") and live drilling play a major role in training, and a premium is placed on performance, especially in competition, in relation to progress and ascension through its ranking system.
A martial art, combat sport, and a self defense system that focuses on grappling and especially ground fighting. BJJ came to be its own art through the experimentations, practices, and adaptation from the Judo knowledge of Carlos and Hélio Gracie, who then passed their knowledge on to their extended family.
Boxing is a combat sport in which two people engage in a contest
of strength, speed, reflexes, endurance, and will, by throwing punches at each other, usually with gloved hands. Historically, the goals have been to weaken and knock down the opponent.
Amateur boxing is both an Olympic and Commonwealth sport and is a common fixture in most international games—it also has its own World Championships. Boxing is supervised by a referee over a series of one- to three-minute intervals called rounds. The result is decided when an opponent is deemed incapable to continue by a referee, is disqualified for breaking a rule, resigns by throwing in a towel, or is pronounced the winner or loser based on the judges' scorecards at the end of the contest.
