Iv heard in the past that working out at a young age will stunt your growth, i was wondering if this is true? I could look it up but its funner this way. Im 15 and iv been working on my arms for about half a year now, just with some 10 pounds weights, but almost every day i do it. Im about 5'11 or so. Even if it does it wont slow me down but i was just thinking about it.
