WATP is Walk Away The Pounds. I don't remember the name of the lady who created the video though (it's a set of videos for walking, but you walk in your home in front of your TV).
There is more to it than just walking though. Eeek! I shouldn't try to answer questions I don't know the complete answer to! It looks like a great program though - I have seen the commercial on TV and it seems like it gets you moving, more than just your legs!
