Hi,
I've just started to learn Tai Chi. From what little I know there are a few different "forms". I'm learning the short form- 28 moves- of Tai Chi Chuan. To complete this will take 8 weeks (i'm on week 7). I really enjoy the fluid movement of this excerise and feel extremely "grounded" by it.
I need to practise it twice a day & really work at remembering the moves correctly. Go down to the place and look and see if you think that it's for you!
Here's some Tai Chi sites:

Good Luck,
