Not to start any kind of rant, but you're 16 and your username is "Nobama." Seriously? Like, seriously? Okay then.
Listen and absorb everything MattyG said. Simple guidelines are best for now.
According to your profile info, you're 5'7", 140 pounds, and "21.9% bodyfat." How in the world to you come up with that bodyfat percentage?
If it was a handheld machine, they're notoriously inaccurate. If someone used calipers, they can be inaccurate depending on the person taking the measurement. I suggest you forget everything about bodyfat percentages and concentrate on reliable tape measurements, photos, and how clothes are fitting.
Starting today, get on this basic routine, which I believe is a great start for younger guys:
Mon., Wed., and Fri.
Squat 2x15 (No weight, keep both feet flat on the floor.)
Push-up 2x15 (On your toes, go until the chest almost touches the floor.)
Lunge 2x15 (Alternate legs, 1 rep left/1 rep right.)
Neutral-grip pull-up 2x15 (assisted if necessary. Try to find beams/monkey bars/tree branch/something. Could be substituted with inverted rows.)
Plank 2x15-count (Hold the top part of a push-up, on the toes, arms straight, keep the whole body straight. Count to 15.)
Burpee/squat thrust 2x15
By the time that whole workout is easy, you'll be ready to start using the gym.
