David Pogue published an excellent Blog post on the NY Times website called "The Wii Workout".  David extoles the virtues of the Wii for kids fitness.  From the article: "I am, however, suggesting that the Wii is infinitely better for our kids’ health than any other video or computer game — in fact, better than just about any other indoor activity." 

WorkoutWithWii of course fully agrees with Mr. Pogue and his message that the Wii is a great way to get kids physically active.  And remember - make sure you stretch before your next Wii gaming session.
