Thinkingdeeper In the sixties and seventies I think pretty much every school (at least in the South) had a proper playing field and a gym that had facilities for tennis and badminton. We had to do pretty much all the ordinary Olympic sports at one time or another it seemed to me plus cricket, rugby, tennis, badminton, hockey, cross country running. But the usual PE was football for the boys, netball or hockey for the girls, plus gymnastics for everyone.
I was uniformly rubbish at pretty much all of it but it did at least give us all some exercise. Later on in the sixth form it became possible to skip games if you could demonstrate that you were using the time for something academic so several of us did that. Of course in those days hardly anyone was taken to school by car, we either went by bus or walked. I walked so that I could save up the bus fare for something more interesting and that gave me at least an hour or moderate exercise every day.
