Brazilian Jiu-Jitsu

Brazilian Jiu-Jitsu (BJJ) is a martial art and combat sport that focuses on grappling and especially ground fighting with the goal of gaining a dominant position and using joint-locks and chokeholds to force an opponent to submit or be knocked out depending on what submission method is used. It promotes the principle that a smaller, weaker person using leverage and proper technique can successfully defend against a bigger, stronger assailant. BJJ can be trained for self defense, sport grappling tournaments (gi and no-gi) and mixed martial arts (MMA) competition. 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.
Wrestling

Wrestling is the act of physical engagement between two people in which each wrestler strives to get an advantage over, or control of, the opponent. Physical techniques which embody the style of wrestling are clinching, holding, locking, and leverage. Avoiding techniques likely to lead to serious injury, the basic principles of wrestling are closely related to those of military hand-to-hand combat or self-defence systems. Many styles of wrestling are known all over the world and have long histories. Amateur wrestling has been an Olympic sport for over one hundred years and professional wrestling is a popular form of entertainment as well as an art form.
Muay Thai

Muay Thai is a form of "hard martial art" practiced in large parts of the world, including Thailand and other Southeast Asian countries. Traditional Muay Thai practiced today varies significantly from the ancient art muay boran and uses kicks and punches in a ring with gloves similar to those used in Western boxing. Muay Thai is referred to as "The Art of the Eight Limbs", as the hands, shins, elbows, and knees are all used extensively in this art. A practitioner of Muay Thai ("nak muay") thus has the ability to execute strikes using eight "points of contact," as opposed to "two points" (fists) in Western boxing and "four points" (fists, feet) used in the primarily sport-oriented forms of martial arts.
Boxing

Boxing (sometimes also known as Western boxing or pugilism) is a combat sport in which two participants, generally of similar weight, fight each other with their fists. Boxing is supervised by a referee and is typically engaged in during a series of one to three-minute intervals called rounds. Victory is achieved if the opponent is knocked down and unable to get up before the referee counts to ten seconds (a Knockout, or KO) or if the opponent is deemed too injured to continue (a Technical Knockout, or TKO). If there is no stoppage of the fight before an agreed number of rounds, a winner is determined either by the referee's decision or by judges' scorecards.
