Teen weight training?

Train hard! I hate how people think that weight training will make you short, it is an old myth that is still floating around. Using steroids does that the possibility to cause your growth plates to fuse together early though, so don't use them, duh. Weight training has the ability to increase your HGH (human growth hormone) to make you taller and leaner. Also, for the weight, you should do 6-10 reps, with the last rep leaving you not able to do anymore using good form. An example would be biceps curls, if you can do 15 reps, add more weight, and then with the added weight do as many as you can without arching your back, do that until your in the 6-10 range. Once you go over 10 add more weight.
