Why some asian schools require students to exercise before each school day?

WHY NOT? i think it is a good thing to exercise before going to class because exercise open our mind and energy. it also help the brain stay fresh and healthy for a new day. beside, Asian students study more than any country in the world.

for example: students in South Korea will not go back home after 3am. they will stay after school to study or go to the library. the only time they will go home is 4am and go to school 8 or 9am
