Rainy Day Exercise

It is raining and I need to exercise. This happens a lot in New England, especially in November. Sometimes I just gear up and go outside anyway. But now it is dark and I need to do my cardio. So I won't be going in the woods now! Here are some options:

1. Dance
2. Run up and down the stairs
3. Do a jumping/plyometrics routine
4. Do an exercise DVD or find something at On Demand

I think I will dance. I can incorporate that with some ab work. Sounds good to me!
