okay as i mentioned u missed training triceps, calves, forearms, legs, so you need to start training these
you fail to do the important lifts like weighted pull ups, bench press, dips, deadlifts, squats, barbell shoulder press, skullcrushers, barbell curl etc
your training split sucks, train chest and back seperatly, u need rest days between chest, back and LEGS since u should be training legs
ur diet suks arse, u are unaware or ur protein consumptions carb consumptions and fats
you need ALOT more carbs, and i mean ALOT
ur protein intake is fine since all you seem to do is waste alot of money on shakes after shakes, 1-2 shakes a day is more then enough, try eating real food, u barely eat anything and are already relying on shakes
i could go on but the point is theres ALOT of problems ith your workout schedule and diet
now you need to start researching on the internet and learning how to train and eat to gain muscle
as for your ORIGINAL question, wat can i expect to gain?
youd be lucky to put on a few pounds in a year
but considering you go school id say puberty might make you agin abit more weight due to development of your body and height, but alwise nothing else
BUT heres a basic rule of thumb
en your correct your workout, and train properly, and start eating REAL food and not rely on shakes
heres a simple principle to follow if you wanna gain weight
weigh yourself every week, IF your nto gaining weight add more food into your daily diet
e.g if one week you dont gain any weight, add 1 extra cup of cereal to your breakfast bowl every day
the following week if you dont gain weight, add 1 more cup of cereal
eventually you will begin to gain weight, and depending on ho your training is ill determine whether its fat or muscle
