Thanks for the very detailed response Jason. You have certainly given me lots to think over.
I took a class a few years ago when I lived in Milwaukee.
When I moved to Madison I tried a course at the YMCA, since I was a member already, and it was fine.
I recently decided to find a proper teacher and take the whole thing a lot more seriously.
I really enjoyed the heat of the Birkram method. I felt much more felixible afterwards, maybe even taller.
Some of my enjoyment might have stemmed from the fact that it was -5 degrees (F) outside and I got to go into a 90+ degree room and sweat for an hour and a half.
One of the instructors there acutally recommend that I try the Astanga class from a competitior of hers. At the other studio they offered Astanga, but suggested that I might want to try Forrest yoga. I tried it and it was also a good class.
I feel very comfortable with all of the instructors and would be happy to go with any of them. The money thing only comes into play with how often I could do a formal class. Once a week with the studio or twice a week with the YMCA. The rest of my time is devoted to other activities. I play underwater hockey once or twice a week and hit the pool on my other free nights.
Yoga studios are all over the place by my house, but no Qi Gong close enough for me to try.
