Fitness Room Flooring

I saw this and i really liked it i saw the demo video on my wii and it looked really good so first off i was wondering does it work? will it give you more stamina and strength and all that? secondly if it does work will it be one of those things where you spend the money on it but then after a couple of months it gets left in your room and you never use it. So my question is, is it worth it to buy it? P.S. the balance board works with other games to right?
