A high-tech gym. Wow, this is so cool, I love the gym that I'm at, but it could be so much cooler if all the equipment was networked together and could track my progress. I used to belong to a gym in the Netherlands where they had all the cardio equipment hooked up via a wireless network, you would sign in to a touch screen when you went into the gym, then, when you went to a cardio machine, you would just have to type in your code and it would setup your own personal workout for you.
