I think I have a problem. Got home from the agility trial and just felt like I had to do one more thing. Besides, my blood sugar had been high all day (baked potatos, even small ones, are not a good idea, by the way).
So I called around, picked a 24-hour fitness somewhat near the house (not close enough to ever join), and did 35 minutes on the ellipical trainer. (Note to self: get a lock)
