T'ai chi ch'uan training involves five elements, taolu (solo hand and weapons routines/forms), neigong & qigong (breathing, movement and awareness exercises and meditation), tuishou (response drills) and sanshou (self defence techniques). While t'ai chi ch'uan is typified by some for its slow movements, many t'ai chi styles (including the three most popular – Yang, Wu, and Chen) – have secondary forms with faster pace. Some traditional schools of t'ai chi teach partner exercises known as tuishou ("pushing hands"), and martial applications of the taolu's (forms') postures.
