The blurb underneath the video makes an interesting point ( I've adapted it from Googletranslate in an attempt to make it more coherent). What do we think?

People who normally condemn weight-training for children and adolescents often claim that the issue is the impact of such biomechanical activity. However, there's an inconsistency in their own statements recommending basketball, volleyball, jumping, among other sports with more traditional vertical impact. If these activities are considered healthy, then it's actually illogical to condemn bodybuilding. Any normal child runs, jumps and throws and they are still growing. It's the excess of activity, inadequate guidance or lack of activity that are harmful to children and adolescents...Physical activity in adolescence accelerates longitudinal growth, the thickness of the bones, the release of testosterone and growth hormone. These benefits are most evident with bodybuilding. (Claw Academy).
