well, maybe if you were genuinely malnourished from birth, it may have some effect, but assuming you have not been malnourished and locked in an attick from birth, i really wouldnt worry
Look at at this way, how awesome do you think Stallone's nutritional and exercise regime has been since he was a young teen? Top notch right? so how come he is only like 5' 7" ? surely he should be 6'5" or something by now?
Whats he doing wrong? Nothing. Your height is already decided in your Genes. Just eat a balanced diet and see what happens.Trust me, if there were a way of 'stretching' people out, then NBA teams would be sponsoring special schools where new talent would be sent to undergo special growth regimes. As you may have noticed, this does not happen, as no such 'cures' for shortness exist.Sorry.
