I've been going to Stroller Strides recently and love it. It's an hour long workout outside (and at the mall in the winter). If you're interested in more details let me know (or google Treasure Valley Stroller Strides).
I'm not due until December, but I'd love some info on this, as an option to get in back in shape once I give birth Plus - group stuff is great, I don't have any "mom" friends yet!
