To anyone who thinks you can't get a good work out using the Wii, I'm hear to tell you, you're wrong. We have a Wii and a few games and some make me sore the next day. There's a canoe game on the Wii Resort that really works my arms. With the Wii Fit there are tons of games that give you a good aerobic workout, or a good ab workout, or a good leg or arm workout. You can get pretty sweaty trying these types of games. The best part is you're having so much fun it doesn't feel like a workout and that to me, keeps me wanting to do it longer. The Wii is great!
