Halo Workout
At the end of a Halo game, everyone playing takes the number of deaths they had during the last round, does that many push-ups and then proceeds to do double that number of sit-ups. The goal is to equal out days of Halo play with a little excercise.
Alright, I had seven deaths. I'll do the Halo Workout and be back in seven push-ups and fourteen sit-ups.
