Walking DVDs

PeekABooGirl

Does anyone do them? I enjoy walking HOWEVER often don't get the opportunity to go outside to do so because taking my kids along means a very SLOW walk! I'm wondering how good of a walk you can get in by doing one of those DVD's. Does it really get your heart rate pumping, etc? Have you lost weight and seen any difference in clothing sizes in doing walking alone?

THANKS!!
PS would love to know which DVD's are good ones!
