Query: It really works

I have a hard time sticking to an exercise program. I have been using this program going on five weeks now. I have lost 12 pounds so far. It's easy to use. No calories to count. You can basically eat what you want you just need to watch your portion sizes. I am amazed at how easy it is to use and stick with. Would recommend to anyone who wants to lose a little or a lot of weight.
