Using the wii vs. wii fit
I love my wii. To be honest, I enjoy the other games more than the wii fit, but I really like my wii fit too. I find that the wii fit activities aren't enough of a workout for me, but they're still enjoyable. The game I use for exercise a lot is "Just Dance". It's a ton of fun, and you get a good workout. I look like an idiot while I'm playing this game, but I think everyone does.
I do highly recommend the wii for working out....
