Body for Life

I'm thinking about doing Body for Life. If you haven't heard of it, it's a 12-week program involving both nutrition and exercise plans. I'm still reading up about it (checked out the book from the library yesterday). If you've done it and/or have any advice about it, email me or comment here. I've been hearing a lot about it from people on the Cathe.com forums so I'm interested in giving it a try. I need a good kick in the pants to lose a bit more weight.
