This is TCM doing some preliminary pre-class movements - he called it getting warmed up.
When I went by the Center to Joe up, I was told he was still in class so I stood outside the door and watched for a few minutes .
TCM has informed me that I have to be very vigilant as he is now able to spring around now like a gazelle. And, I'd better not be sneaking up behind him as he uses some of his new Tai Chi forms such as "Single Whip", "Part the Wild Horses Mane", "Grasp The Peacock's Tail", "Repulse Monkey", hmmm.
