Martial arts refer to specific kinds of training and combat techniques originally developed in ancient times. There are many styles of martial arts; they include Asian practices such as karate, judo, aikido, kung fu, and tae kwon do, and Afro-Brazilian practices like capoeira and jiu-jitsu. These techniques have evolved into sport and recreation, with many facilities, also called dojos, instructing kids and adults these ancient practices. While some take the classes to learn self-defense, many seek them out as a fitness program. Most martial arts jobs today are teaching roles in a dojo. You may start as an assistant, helping the primary coach instruct the students. After gaining experience, you may move into a primary teaching position and lead your own class.
