According to IGN, Nintendo just might be trying to get you off of the couch and into a workout routine with the Wii, doing for your body what Brain Age on the DS did for your mind. They found this news via Bloomberg, which claims that Nintendo is in the process of making new diet-based software for the console.
This idea sounds about right, but in what way could they guarantee an actual fitness experience through use of the Wiimote? Would they try to market another peripheral for the console or would the player just jog in place, for instance? Sure, we could imagine the Wiimote playing a role in some kind of exercise routine where stretching was a major aspect or perhaps some kind of yoga variant, but we know that is in no way going to pump you up.
