I've been working on a private client project recently, thinking about how games and elements of gaming can be used to promote physical activity and improve health outcomes.  I am a sporadic gym go-er myself, and I tend to prefer the rowing machine to any of the other cardio equipment, even though it doesn't have a television or any bells and whistles.  But this morning, as I was leaving, I noticed that my gym has two brand-new Expresso Fitness stationary bikes, which I had just been reading about for my project.
