You are much farther along than I am, but I did take a year of instruction from a VERY good teacher in CT, years ago, and I find the reflexes developed continue to be spot on, as they say.

I am out of shape from years of a leaky heart valve, but now that it's been replaced, I have a really neat video called Qi gong for beginners which I am s l o w l y working up, plus a Toga (how's that for a typo?) Yoga for the Rest of Us one. I hope to get back into a Tai Chi class in the next year or two.
