Change Skill school of Practical Tai Chi Chuan provides a separate, opt-in workstream for fight training. It is typically embedded in regular classes, for those who wish to work on this, and open to anyone whether or not they are studying the style.
Most Tai Chi practitioners do not actually want to undergo the kind of intensive physical conditioning required for fighting, and would not want to expose themselves to the risk of potentially permanent damage from various types of full-contact strikes, including to the head (though these are strictly controlled).
Although standard PTCCI training involves an important ‘martial aspect’, this kind of dedicated fight training is therefore separated out.
