Working at home can pack on a pounds after a few years. It's good to have low fat snacks on hand so it doesn't get out of control. I've tried quite a few exercise DVD over the years including the Wii exercise game. With working at home and taking care of the kids at the same time doesn't leave much time. The most fun that I've had lately is with the wii zumba. I love how they walk you through step per step and I can start it over again and again to learn everything the correct way and it's a lot of fun at the same time.
