10 weeks is 2-and-a-half months, not 3-4. Sorry, but that was bugging me.
F-o-o-d. Problem solved.
Dude, roast beef sandwiches, whole eggs, milk, and peanut butter should become staples of your daily menu.
That's all well and good. With where you're at (at your age, and training (in)experience), any consistent lifting will be fine. I will say, though, that I'd like to see you be sure to incorporate push-ups, pull-ups, and no-weight squats and/or lunges into your routine, as well as keep a majority of your lifting in the 8-10 rep range, due to your age.
