if you want to get bigger… Eat EAT EAT and EAT
once you get enough muscle the fat will just start melting off ya…muscle is what burns fat…
also you can stay away from shit like Coke, ice cream, and garbage food…
foods rich in protein and vitamins, and carbs and yes you do have to eat some fat… to function so… pretty much just eat until you are about the burst and be intense at the gym
and being pissed that your chest isn’t that big… genetics dictates alot… it may be a constant battle for you, but hard fucking work can reverse it
