Hi Shanda,
I has a "surprise" C-Section in October and I was able to work out doing easy stuff around 6 weeks afterward. I didn't always do it, but I was physically able, if not mentally in the frame of mind!! I did the Cindy Crawford "New Dimension" or something like that, which features Kathy Kaehler. It's good, but if you're used to Cathe (and I assume you are!), you'll outgrow it quicker. (I kept mine in case I have another baby.)
Good luck and enjoy your precious bundle on arrival!
