MMA Fighters — Compound Martial Arts

Group of Chinese martial arts

Neijia is the collective name for the internal Chinese martial arts. It relates to those martial arts occupied with spiritual, mental or qi-related aspects, as opposed to an "external" approach focused on physiological aspects. The distinction dates to the 17th century, but its modern application is due to publications by Sun Lutang, dating to the period of 1915 to 1928. Neijin is developed by using neigong or "internal changes", contrasted with waigong or "external exercises".
