Just got to work after my first foray into yoga. It was Bikram Yoga, so I was sweaty. But I gotta tell you, it was pretty awesome. There are certainly things that didn't feel good-- mostly the Japanese sitting pose (on knees, sitting back on ankles), but supposedly it gets better with practice.
I plan to add it into my rotation: Now I'm doing yoga on Friday, Zumba on Saturday and Sunday, and belly dancing on Monday.
