I still suggest starting with the nutrition advice I mentioned in your other thread, as well as starting off with that basic bodyweight plan.
I generally recommend younger guys start with bodyweight training to learn the most basic form of exercise before moving to added resistance. It's a simple way to build strength, muscle, conditioning, and coordination, and it prepares your still-young joints and support structures to more safely deal with the stresses of heavier lifting.
Once you can handle your bodyweight in a variety of movements, then jump right on a well-designed routine. And nope, the routine you listed in your first post above is not well designed, for some of the reasons already brought up.

Either use a neutral grip (where your palms face each other) or do inverted rows a.k.a fat man pull-ups:
