Clearly some people don’t really know what they are talking about here.
I lived in Illinois where four years of PE was required at the high school level. It was a total waste of time and contributed very little to my physical fitness. I got far more valuable experiences playing volleyball at the park district and beach with my friends and running and biking the bike trails on my own. My kids are not missing out on anything because they miss public school PE. They get plenty of exercise on their own. They play team games at youth groups and camps. They play ultimate and spikeball and disc golf with their friends. It’s not like public school is the only place that offers physical activities or team comaraderie.
