You can do anything you want to do!! If WATP is what you want to do, then go for it. I know many people who use it exclusively and have lost weight. Personally I like it but when I'm on top of my game its not difficult enough. I like the ones that incorporate jogging but even those sometimes feel too mild. Right now I'm looking into doing the 5 mile walk. Actually, it might be in my mailbox right now. If these are what you like and you will stick to, thats half the battle. You aren't going to keep up with something you hate. And as I said, I have heard of many women who have been successful at weight loss while using only WATP. That being said, I'm a big proponate of weight training/resistence training. If you could get some of that in as well it would be great.
