To the gym, where I used the elliptical machine for 30 easy minutes. My knee was hurting a little. That's not a good sign, when the elliptical machine hurts your knee.
Then an hour of Pilates. I felt very stinky -- I was wearing the same shirt I wore to run on Sunday, plus my feet stunk, and I had to fart (although, due to a massive application of willpower, I was able to hold it).
