Jiu Jitsu is a martial art and combat sport system that focuses on grappling and especially ground fighting. Jiu Jitsu promotes the concept that a smaller, weaker person can successfully defend themselves or another 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. Jiu Jitsu training can be used for sport grappling tournaments and in self-defense situations. Sparring (commonly referred to as "rolling" within the Jiu Jitsu community) 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.
Muay Thai or Thai boxing is a combat sport of Thailand that uses stand-up striking along with various clinching techniques. This physical and mental discipline which includes combat on shins is known as "the art of eight limbs" because it is characterized by the combined use of fists, elbows, knees, shins, being associated with a good physical preparation that makes a full-contact fighter very efficient. Muay Thai became widespread internationally in the twentieth century, when practitioners defeated notable practitioners of other martial arts.
