I would advise you to seek out a fitness instructor. There is very little that you can do about how tall you will be. At least not naturally and the side effects of unnatural methods are not very pleasant.
To enhance your natural potential I would suggest participating in a variety of activities like running, biking, swimming, sports, etc. Eat as healthy a diet as you can. Get plenty of rest. And never exercise sore muscles or injured muscles/joints without the advice of a professional.
