This was my thinking. I've had two days of training with Howard and it is going to be at least a few months before I get a chance to train with him again. I was just curious as to whether "generically" Tai Chi would get my body moving in a better way.
My personal experience and opinion. Don't take any Tai Chi. Work on the solo training, train at home, at work, everywhere. Go to the dojo and work on the paired partner exercises to burn in the solo training you're doing. Work to the point of failure, further expanding that point.
That will get your body moving in a better way. Might not seem like it in the short run, but it does work.
