If you were a precocious fitness enthusiast, your parents may have warned you to stay away from the weight room because of a belief that it might stunt your growth.
While lifting weights can be dangerous if it's not done correctly, there is no evidence that the workout will make you shorter than you would otherwise be. As the PictureFit video above explains, the theory went that lifting weights would negatively affect your growth plates while your adolescent body worked to be strong and tall. The fact of the matter is this just isn't true, and there are many other activities (like football) that can be more dangerous for a little one.
Consider this myth busted.
