text: does lifting weights when ur 13 years old stunt your growth?   here you go this should help:  "the whole notion of growth being stunted by weight lifting is a myth. it didn't stunt the growth of shaquille o'neal, david robinson, karl malone, michael vick, etc. they all started lifting in their early teens, and all have gone on to be well over 6' tall and star in professional sports.   dave draper and arnold schwarzenegger started lifting very  young and both are 6'1" or taller. lou ferrigno started  working out at 14 years old at the height of 5' 9" and grew to 6' 5" - taller then anyone in his family!  so the answer is no, weightlifting does not stunt height growth, or any other kind of growth, for that matter. there is no scientific evidence to support such ideas and, in fact, books such as the russian, school of height, suggest that weight training may stimulate growth. the latest weight training studies done on teens showed only positive effects.   i'd also point out that activities such as running and jumping create forces on the body that are six to eight times one's body weight. the compression forces on his legs and spine are far greater in running and jumping than they will ever be in squatting or pressing over head.   not only will proper weight training not stunt growth, it allows teens to grow up with stronger muscles and bones, along with a healthy lifestyle. it certainly benefits any other sport they engage in."
