I quite liked some aspects of it (netball, hockey, other team games etc.) but I wasn't very good at it which meant that I didn't get any encouragement or attention from the teachers as I was never going to be on the school team, for example. I wouldn't say it put me off exercise, but certainly it didn't help. I felt like a bit of a write-off, whereas actually I could have improved with some attention and encouragement but that wasn't on offer. And there was absolutely no emphasis on PE for enjoyment/fitness and finding out what you liked and were good at. Some aspects of it were quite sadistic too (bleep test etc.) and I always felt sorry for the children who came last as it was a bit humiliating. I was usually fairly near the bottom but not quite there 😆.
Unless PE has improved a lot since I was at school, I don't see the point in it. It would be far better for PE to be focused around giving children 'tasters' in terms of the local sports and activities available, and then paid access to these activities and an afternoon off school per week to attend them wit instructors who actually care about their development and enjoyment.
I enjoy exercise now despite PE rather than because of it and I think that's a bit sad.
