Kids have trainers

In America many parents are worrying about their children's health. For example children's wight and lack of exercise and so on. So they pay for children's trainer who let children do exercise by using $40 to $60 every year. Many many children have their trainers. That mean P.E. taken in school is not enough for children to prevent from lacking of exercise. I think we don't have to let our children bring trainers. Parents should play with their children. If parents do that idea, it become very precious time for children and parents. And they can grow up their communication. So please think about this topic. And what will you do for your children to exercise?
