Every time I think of this I think "If my gym were smarter about game mechanics and WoWed up all their participation stats I would have +5 Abs of Steel and Epic Purple Arteries by the end of summer." (They've taken wee baby steps: at the end of the workout the screen will say "You burned 120 calories, which is an apple." and "Yay! You've completed your 17th Tokyo Marathon." That's great, but I think two guys and a couple boxes of ramen could do <i>much</i> better.)
