And finally, I come bearing some bad news. It seems that working out via Wii? Not really that great a work-out after all. While it looks like the Wii does help you burn more calories than a more sedentary game system, we're talking 180 calories an hour for something like tennis - only 20 calories more than the can of soda sitting next to me. In contrast, actual tennis burns around 320 calories an hour.
Now granted, more movement is good - but for all those parents who bought the Wii this Christmas with goals of getting their coach potato kids up and both moving and healthier? This is bound to be disappointing news.
