Mixed martial arts are recognised as a foundation for striking in mixed martial arts, and are both widely practiced and taught. Although both may seem identical, each has different techniques. Muay Thai originated in Thailand, and is known as the "art of eight limbs", which refers to the use of the legs, knees, elbows and fists.
