Oh my gosh I have a new passion. I have just started practicing Bikram Yoga and it is the most amazing workout I have ever experienced. I am a beginner so I can't do all of the poses but I love the way I feel afterwards. I am relaxed, yet energized and all the sweating from the heat leaves me feeling clean and purified. If you get the chance to take a class I highly recommend it. Any yoga class pretty much rocks but Bikram's is by far my favorite. Here are some links for reference, just in case you are not familiar and are interested:
