I had a great session this morning. The instructor this morning was Alex, who is currently my favorite instructor-- she seems to get me to do things today that I thought were weeks or months away. I worked a lot on my focus today. I had some difficulty because my left knee has really started to bother me. I think this is because I really upped my running schedule a few weeks back. But the advice I've gotten from Bikram's book is to go ahead and try to continue, but cautiously.
