Just my own 2 cents. As somebody who has practised Tai Chi for over 30 years AND coached champion MMA fighters, I figure I should respond to the 'challenge' video! Both sides are wrong: Tai Chi is NOT a scam, and Tai Chi is NOT too deadly for the cage. I'm afraid the truth is a little more mundane
In this clip, I actually demonstrate a tai chi posture, then show how to drill it for self defence/MMA and a little free sparring. Now tell me it isn't 'real' tai chi....
