You mean, the first sport that comes to mind when I think "Olympics?" I mean, I know it's not as popular as the other sports these days, but I'm pretty sure that the little "running" and "jumping" competitions had nowhere near as much draw as the wrestling back in the day.
That being said, this is pretty awesome. I know a few people who exercise at this place where the entire room is like a big trampoline and I've always wanted to check it out. I guess you see stuff like this all the time. More exciting than high diving anyway.
