Inevitably you'll get bigger even training for strength and vice versa. Just they'll come secondary to what you are specifically training for. If you are 16 and just getting into lifting and especially if you are looking into strength training, which IMO is where you should start because after you develop good strength and technique it's far easier to move into hypertrophy for size later. I would really recommend that you look into Starting Strength by Mark Ripptoe. It's an awesome program to start out with based on the basics of strength.
