you will def get bigger in the next few years. hey i was big when i was your age, and i just got bigger
. i was 240 when i was 14. or you cna loot at some athletes. dennis rodman was 6 feet tall when he went to college. when he wen tto the nba he was 6'9. that is a bets case scenerio but you will grow.
also even though you may eat a lot doesnt mean you eat things that will put weight on you. dont go thinking you have to start eating a whole bunch of heavy things though.
and you are at the age where you should start lifting to. so look through some of those training routines posted. the guys on this forum have a lot of knowledge and def share some good things.
so my advice. post what you are eating and let the guys here critique you, and start doing those good ole excersices normal people hate to do. a2g squats, dead lifts, and pull ups. also hop on that bench and do some military presses. look up some routines and get the ones that fits you and listen to what people post about yrou diet
