I just bought a Wii and have a few games. I really wanted it to make exercise more fun. I'm not looking for a computerized personal trainer. I want games that will make me get a good workout without getting really bored. So far, I found Wii Sports Boxing to be good and Baseball practice is alright too.
What other games can give me a really good workout? Also, which games sound like they would give a workout but are just old-school, sit on your bottom and press buttons type of games?
There are two main exercise games right now: Wii Fit Plus [1], and EA Sports Active [2]. They are computerized personal trainers, however most of the activities are a good workout. As they are "personal trainer games", they give you incentives to complete the activities (playing more unlocks new activities), so hopefully you won't get bored.
Here are some specs on how much of a work out you get:
For comparison a 30 minute run at 6 mph for a man weighing 180lb is 404 calories

Played with the Wiimote and Nunchuk, you'll get a similar level of exercise as that of Wii Sports' boxing game. It's also a very highly rated game.
Your best bet, though, is to go with Kevin on Wii Fit (Plus). It's not dull or dry, so it's very easy to keep up with and have fun doing so.

I used to play DDR a lot, and Wii Fit never tired me nearly as much when I was playing with it. There are multiple DDR games for Wii you could find, just make sure you're not living above someone. :)
I have no personal experience with them, but I've heard from others that the Just Dance [1] series of games are pretty fun with a group and definitely get you off the couch.
