Physical education should be compulsory because,Students who have Physical Education on a regular basis are more likely to be healthy and fit. They will sleep better at night and that will help them stay awake and focused in their classes. Many children do not get exercise outside of school, preferring video games to going outside to play. Requiring children to take Physical Education classes can encourage them to seek out fun activities that help them be healthy, throughout their lifetime. Physical activity is also proven to help the brain function better. So when your kid is done with physical education he can focus a little better and develop his motor skills by the way he plays and moves, so he becomes more fit like hand eye cooperation. Mental skills are also developed by physical education because it keeps the player focused in the game and to be able to accept winning or losing. Last but not least social skills are developed also like cooperation with other people.
Students who do not want to exercise and benefit themselves will not do so. They will only sit on the sidelines doing nothing. Even if physical education is compulsory, students will make their own decisions about their own fitness. That cannot be changed. We might as well let them use their time to do something productive. It also causes kids to feel bad about their physical ability and strength. Another reason is that it is not conducted well and there is no good supervision for it to show results.
In my opinion I think it should be compulsory because it will make a better future for our children and makes them look better too and lower the risk of obesity diseases. So definitely if someone had good skills and looked good will turn out to be a successful
