Dunno what PE is like in the states but in England at my school it was a once a week double period occurence. Depending on the season we did different things. Autumn was Rugby, Winter was Cross Country (ahh the pain), Spring was Rugby for the team players and assorted sports for everyone else (Hockey, Football etc) followed finally by summer which was dedicated to Athletics. Within this overall plan there was a rotating three week stint in a local indoor fitness centre where you could do either Badminton or a gym workout (this indoor stuff was only at year 10/11 and sixth form).
That was all good times, whether up on the field or in the centre. The only drag was Cross Country, man that sucked. It was winter so the fields were less field like and more bog like and the school didn't want them absolutetely annihilated over winter so they'd still be playable for Rugby matches. So we ran around the edge of the field, off the field to a local park, which we ran around, then ran back to our field, which we ran around again, then we got changed, and died. I think it was between three and four miles, good memories.
Finally, we also had PE theory, which taught us some applicable and extra specific Biology and the merits of a healthy lifestyle.
PS Apparently I've said alot about PE. If you've read it all have a +1 internet. If you've just read this post script and try to claim the +1 you, in fact, get -10. Moral of the story, put some effort in! (applies to PE too)
