As long as you don't do it to the extreme, you should be fine.
would you consider to keep on doing exercise and weight lifts ?
Heavy exercising/weight lifting, coffee, and a couple other things have been speculated to stunt a person's growth, but there really isn't much evidence on it. You will typically grow to the height of your dad, so how ever tall he is, you will grow to a very similar height. You will also grow until about your early 20s, so you have a number of years before you reach that point. Try not to worry about it and enjoy your teens.
Hi you have got everthing going for you.You are still growing you have time on your side go for it Take Care...Bob
