I just purchased this for my kids, it is such a fun game!!
My son and I both need to become more active, and this is a great way for us to get fit together when it's raining and the park is a no-go.
The mat comes with fun challenging games. If you are really out of shape, you might try the Wii Fit board. You hop, jump and run. On some you sit and use your hands to paddle. Enough games to keep you busy for hours. The only drawback is that when you are jumping, you can miss the arrows and it is kind of hard to store. I use the large ziplock storage bag. I haven't really seen it advertised much which is a shame. The mat is not wireless, so you have to be careful with the cord. You will definitely get some exercise with this. Loads of fun!
