Like most guys in the gaming industry I sit at my desk all day, which apparently kills you faster than chicken nuggets, so I try to get up every few minutes and do some exercise. We hung a chin-up bar in the hallway which also lets me kick people in the face as they pass. Look at this bastard ignoring my kung-fu as he dutifully checks the morning news.
In all seriousness though, I think its done wonders for my health. I don't really have time to go to the gym and I don't like to eat healthy (fried stuff is great!) so it is pretty much the only exercise I get on a regular basis, and it only takes a few seconds at a time. Highly recommended for fellow slackers.
