I took Tai Chi in the past, for about 2 years. The first year was a basic class, to learn the "stick" set and to chisel it a bit, and then the second year was more advanced, when you already know all the moves and you practise the form etc. I loved it as I love everything martial arts related and I am sorry I did not continue.
Sometimes I think I would like to do it again but I am spending 6 days a week at the gym already and there just is not time for everything.
It is deceptively 'easy' to perform a set but I was always sweaty afterwards. Not hugely, just a bit. It is an excellent way to keep the joints flexible although I swear one has to Oriental to achieve the perfect fluidity - they must have it in their genes. :-)
Dearest Schumeany: Yes, those are size 4 jeans hugging my posterior. Thank you for being such motivation!!!
