Systema (Система, literally meaning The System) is a Russian martial art. Training includes, but is not limited to: hand-to-hand combat, grappling, knife fighting, and firearms training. Training involves drills and sparring without set kata. In Systema, the body has to be free of tensions, filled with endurance, flexibility, effortless movement, and explosive potential; the "spirit" or psychological state has to be calm, free of anger, irritation, fear, self-pity, delusion, and pride.
Systema focuses on breathing, relaxation, and fluidity of movement, as well as utilizing an attacker's momentum against him and controlling the six body levers (elbows, neck, knees, waist, ankles, and shoulders) through pressure point application, striking, and weapon applications. As a discipline, it is becoming more and more popular among police and security forces and it is taught by several practitioners inside and outside Russia. There are two schools of systema, Systema Kadochnikova, Systema Ryabko.
BJJ promotes the concept that a smaller, weaker person can successfully defend 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 training can be used for sport grappling tournaments and in self-defense situations.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.
Since its inception in 1882, its parent art of judo was separated from older systems of Japanese jujutsu by an important difference that was passed on to Brazilian Jiu-Jitsu: it is not solely a martial art, but it is also a sport; a method for promoting physical fitness and building character in young people; and, ultimately, a way (Do) of life.
