I'm 19 yo, 5'11 or 6'0, but I think my clavicles are making me looks worse, my bideltoid is like 18.11 inches and I have a weight of 110 to 119 pounds, I'm very skinny for a genetic disorder, I tried to eat a lot and the result it's just a stomach pain, idk if training can improve one of both, thr height is a help, but too little due to my weight and personality, so I'm trying to improve all I can
