Explanation:
Weight training has been a boys-only thing for a very long time and it has been adapted to fight the male body and its physical capabilities. If they were to offer it to girls now in its current state, it wouldn't be as accepting of a class. It would cause harm to the girls and some of that harm would be temporary and some could be permanent. As much as it would be right for weight training to be offered to girls, it will take some time and adjustments before it could happen.
