Here's another question:

I went to the "Free Weights 101" class the other day (it was lower body, we did mainly squats and I didn't use weights at all...) and then went on a mountain bike ride yesterday. Today I'm so sore I can hardly move. No cramps, just sore muscles. (It's actually nice to feel the muscles in my butt for once, maybe I'm not doomed to have a square butt after all...)

Do you have any specific stretches that might help with the soreness?

I'm trying to pound down the water right now and I think I'll go sit in the tub for a while too. Hopefully I'll be able to get OUT of the tub...
