Back when I was in (US) high school, the only mandatory physical requirement to graduate was one semester of PE (Physical Education). I took mine over the summer, where it was too hot in my state to go outside, so we played volleyball and ping-pong in the air-conditioned gym all summer. I was not a very physical kid, so that was like winning the lottery for me, since those that took it the rest of the year had to run around the track, and do other outdoor activities in the sun.
