BJJ (jiu-jitsu brasileiro)
Brazilian jiu-jitsu (port. jiu-jitsu brasileiro) (abbreviated BJJ) is a martial art made from Japanese jiu-jitsu and Judo. On the one hand brothers Carlos and Helio Gracie are regarded as the founders of brazilian jiu-jitsu in the early 20th century, sometimes reffered to as Gracie Jiu-Jitsu. In Brazil, on the other hand, there are clubs and schools independent of the Gracie families, who dispute to the family concerned that they are the founders of the Brazilian jiu-jitsu, recognizing only their important role in the further development of the sport. Brothers Gracie studied from one of the jiu-jitsu respectively judo-style master Mitsuyo Maeda, who immigrated from Japan to Brazil in the early 20th century. Dissatisfied with some of the techniques, the Gracie brothers developed their own style, which puts the focus on fighting (wrestling) on the ground.
Kick-box is a martial arts originated in the USA, though there are indications that it may have originated in Japan on the basis of boxing, karate, taekwondo, kung fu, and other more or less known martial arts. Guard is taken from boxing. The punching techniques are from boxing, because they are the most effective, the kicking is already slightly different from school to school, although the savate kicks are best, because the kicks in that sport are almost perfected. One rule of thumb when hitting with your foot is that the heel of your standing foot looks at the opponent, because then you are not only hitting with the leg but with the whole body. Otherwise, people are greatly mistaken when they are afraid to train kickboxing because they think that all the bullies are there, and in most cases it is not. Another misconception is that it is not for women, which is just as wrong. An otherwise very good sport that develops both body and spirit, for the most part fighters are quite relaxed and quite mentally strong, and with that comes physical strength.
