One of the ways I have been able to lose weight is by using EA Sports Active for the Wii! Talk about a workout! I love that the exercise challenge you and also count the calories while you workout! I usually do the running, boxing (which is my favorite), and the dancing.
I haven't tried the EA Sports Active 2
but the ratings seem to be pretty good!
They even have one for the guys that love football! The EA Sports Active NFL Training Camp!
