Should P.E be mandatory in school? Yes, it should, study shows that P.E helps out a ton of kids who do not do Active work outside of school and keeps those kids healthy. Yes, it may be tiring but, it helps them in the longer run. In conclusion, I think P.E should be mandatory because of how well it helps unhealthy kids get healthy.
Should P.E be mandatory? No, I believe P.E. does not have to be a necessary class/activity for people to participate in. The reason being is that every single child/teenage grows at their own pace. It is true that one can accumulate an average of basic necessary physical activity required for all humans to go through in order to make sure all of their major physiological components distribute the stress of physical growth as equally as possible but because we are all biochemically altered to be literally different, it should not be mandatory to force a regime that everyone has to abide by at a schedule interval throughout the school curriculum.
