Human Power Generation...

Article below is about a Gym experimenting with human power generation. 

One of the personal reasons I can't stand to exercise is that it's so worthless... 

If I could make all that sweat GOOD for something, then I'd be more likely to do something about it! (It's why I like to bicycle or just work in the yard for exercise. I think at least SOME other people feel this way, too???)  Maybe this is a good way to motivate all those extra American pounds into kilowatt hours???  I can see future post-oil community centers with solar panels and/or wind generators and an "exercise salon" where you could also check your Email, charge your laptop or phone while you "workout"?
If your home energy generation is too expensive or inaccessible, this could be a viable future -- or maybe everyone will be busy and slim enough riding their bikes to get around and working on those backyard gardens?  Of course -- need to set up the infrastructure while gas is still under $100 a barrel...
