I recently saw a Chinese Tai Chi master somewhere in a video who stated that: Tai Chi Chuan is not for relaxation. And that the many people who promote it as such are wrong. He said: when we want to relax only we could better sit on a couch and watch a movie with popcorn. haha So are the effects for an overall wellbeing and health through the practise? What about selfdefense? He aimed at the fact that taijiquan practise is to play between tension and relaxation with no stop in movement. What are your thoughts?
