I think the gym lessons are unnecessary. As we are students, the most crucial thing we need to do is study. And there are actually many burdens in our daily school life. Uncountable homeworks, lessons, group discusses have already full fill our schedule. So there is no time for gym lessons. Furthermore, the stuff in classroom has already made us extremely fatigued, so to make our body exhaust seems to be a nightmare. We can't even breathe after a gym lesson. Above all, gym lesson is not suitable in the school, it should have been canceled.
