Unless you are lifting cars you should be fine.
Science has not proven that lifting weights stunt your growth.
14 is a good age to start lifting.
Good luck! :)
Exercise and lifting weights do not affect your growth or height.
That is a myth it is not true.
If you are doing squats with very heavy weights you may harm the growth plates, but curls can not possible hurt you in any way.
As far as I know, lifting too much for your size can actually limit and prolong your growth. 20 pounds doesn't seem like too much, but I wouldn't go crazy.
As Lestermount says. I swear, I wish we had a "sticky" of some sort for this silly myth.
It dates to the early 1900s and was a lie then.....It still is.
