i dont think its an issue. height is a genetic factor and there are many studies out there that say bodybuilding does not affect one's height or stunt growth.

HOWEVER if the person is below 13 years of age... heavy weight lifting can cause the growth plates in ur bones to close early... causing this "stunted growth".

I started bodybuilding at age 15 and dont think I have issues with my height... both my parents are short anyways so I could just be genetically short too, not cos of weights.

i think the number one issue of youth bodybulding is not stunted growth.... but teens tend to be very gung-ho and enthusiastic about training, and this paired with ego + improper training techniques + inssufficient knowledge can be a recipe for injury. so go slow, do your research and dont be afraid to ask questions.
