Have you ever tried Dance Dance Revolution? It's a pretty fun game where you dance on a mat, and you have to follow the arrows on screen with your feet. It has a cool workout mode, where it counts how many calories you burn per song (based on your weight), and keeps a total. It also allows you to set a goal (mine is 125). You can burn over 100 calories in 20 minutes (depending on the songs you pick). You can even dance with a friend!

 Does anyone else know of fun workouts like this?
