There's a fitness website called Fitocracy where you sign up and track all of your exercise activity, ie running, weight lifting, cycling, etc and receive points based off the difficulty of the activity. Ten pushups is like 15 points, whereas my marathon was something like 4200 points. Anyway, when you have a group of friends, coworkers doing it it becomes fairly encouraging/competitive. I was a little skeptical at first but it's turned out to be a cool little gimmick.
