Check out this new human powered gym design. problem is you're still indoors...
Have you ever pedaled on a stationary bike at the gym and thought to yourself: ‘What if this energy I am exerting could be used for something better than just making me sweat?” Well now a new proposal from architect Mitchell Joachim promises to take all that energy expended at the gym to the next level, by capturing all that exertion and using it to transport people around the rivers of New York City. The River Gym concept is a human-powered floating gym that will provide the user with the one experience that no other gym can provide: floating your workout around Manhattan.
