Tai chi chih (simplified Chinese: 太极智; traditional Chinese: 太極智; pinyin: tàijízhì; Wade–Giles: tʼai4 chi2 chih4) is a series of 19 movements and 1 pose that together make up a meditative form of exercise to which practitioners attribute physical and spiritual health benefits. Some studies have found the practice to reduce stress and relieve certain ailments.
Developed in Albuquerque, New Mexico, in 1974 by Justin Stone (1916 - 2012), tai chi chih has spread mostly through word-of-mouth in a grassroots fashion among practicing individuals. It is now taught and practiced in the US and Canada, France, Italy, New Zealand, Zimbabwe, Namibia, and other countries.
Tai chi chih has visual similarities to t'ai chi ch'uan, but no martial arts aspect. According to practitioners, tai chi chih focuses on circulating, developing and balancing the chi (in the traditional Chinese concept, a kind of spiritual energy residing in every living thing).
