I downloaded some trance/rave-like music from Audio Fuel. It's a company that makes workout music (specifcally running, I think) that sets your pace using beats per minute. Each song is set to help you increase you pace during the run and then maintain a constant pace while you put serious mileage. There's some coaching thrown in, and they even make music for tempo runs, long runs, short runs. You name it. Kind of cool.
Hot Yoga may have been overdoing it, but I felt like getting some more sweat on, and just generally stretching out. I now have some minor pain in my right hamstring that I'm conscious of resting over the next few days.
