Tai Chi Chuan means "ultimate internal martial art". All great Tai Chi Chuan masters since classical times have practised Tai Chi Chuan as a martial art and all Tai Chi Chuan classics have described it as a martial art. Amongst the various dimensions of Tai Chi Chuan, those of internal force cultivation and combat application are necessary if you train Tai Chi Chuan as a martial art. Without internal force a Tai Chi Chuan exponent would have no stamina to last a fight and no striking power to subdue an opponent; without knowing how to apply Tai Chi Chuan techniques to combat he would be helpless when attacked.
