Here's a small list of company athletic sports, I may have forgotten a few:
flag football
ultimate frisbee
grappling
orienteering
functional fitness
foundations of fitness
volleyball
flickerball
handball
basketball
hockey
Depends on the semester.
Both semesters, you'll probably have to play up 2-3 times a week, an hour to an hour and a half, in the middle of the semester. It doesn't start at the beginning of the semester and it finishes well before the end of the semester, depending on how your team does. If your team does well, you have to compete more, it's kind of tournament-style. If your team does more poorly, you're done sooner. Most people don't take company athletics too seriously because while you are graded on it, it's not a big part of your physical grade and it's basically just another thing you're required to do that takes away from your free time. Sometimes you'll also have an hour and a halfish of drill, maybe twice a week, but usually first semester and not so much second semester.
