Should students do phycal exercises.Some people think it's good for their health.After hours of studying in their classrooms,they may need to do sports and enjoy some fresh air.It also helps to become more strong-minded and more efficient in their study.On the other hands,some people also feel it's bad for them to do physical exercises.It could cause injuries and what's more,it takes a lot of time to cool down after vigorous exercises,like running and morning exercises.In my opinion,we should take the advantage of physical exercise and do a little of it every day.
