Its perfectly fine for a boy of his age. If ur concerned for how heard your soon is training maybe you should pay for his trainer yourself pick one you approve of. My brothers all started out at 12 with my dad they started slowly and ate now grown and 1 us a pro bodybuilder. They never got hurt. I don't think working out is bad for him just sounds like head wrong trainer
Hey I know I'm only a 15 year old girl and you won't wanna listen to me, but I know one thing is, your son needs to tell his mother that this isn't healthy for him. Kids should be running laps and doing sit ups, not lifting and pulling all that. If your son doesn't like doing it, he needs to stand up to his mother and tell her, you know what mom, maybe I should just do pe at school. And the courts shouldn't be saying kids need physical activities. Physical activities for kids our age are, like I said, running and doing simple push ups and sit ups. Pushing him is encouraging him to run another lap, not telling him to keep going after he's thrown up. My parents are divorced, and I know that when you're the child and your parents, who already disagree with each other, are arguing over something you should or shouldn't be doing, you need to tell them both, I appreciate what you're trying to get me to do but i don't think I want to do this anymore. Divorced adults will most likely never come to an agreement, because the other parent has too much pride and won't settle with, "Oh maybe your right." I don't know what you can do in court, maybe the next time you see your son, take him to the doctors and ask the doctor to write a note stating he hurt his knee pretty badly and that he shouldn't be doing any major physical activity like that, then bring that to them. And as much as your son doesn't wanna let his mother down, he has to tell her to slow down and at least give him a break every once in a while.
