My goal is to build muscle and mass on upperbody ASAP! I dont want to get HUGE like a body builder but fairly big so please take time to read and please help.
About me-
Im 17, male, weight 70 kg, Height 6ft 1in.

At the gym i do.
I start with cardio a quick 1 kilometer run, to get the blood flowing round my body.

Next i start the weight i do.
Bench press- 3 sets 8 reps, next
Flys- 3 sets 8 reps, next
Lying dumbell tricep extension- 3 sets 8 reps, next
Super set Bicep curls whilst isolating the bicep, 5 reps, followed by as many as i can barbell curls. 3 sets of these. Next
Dumbell shrugs (back)(Hold each time 5 seconds 5 reps 2 sets. next
Bench pull (back) 3 sets 8 reps
Finally i do my abs (Superset)- 20 air bikes, followed without a rest, 20 sit ups (my partner pushes me back down) followed without a rest, 30 seconds holding legs in the air, followed without a rest another 10 situps.

I do this routine 3 times a week.

People have been saying my workout is rubbish and i need to look at a real plan, But however my brother done this workout and i a few months he got BIG! Anyway so on this website in the top left it says find a plan. I dont belive this plan is right for me as i only will be doing each upperbody muscle once a week, ive spoke to my physio who specialises in upperbody he told me to work out on every upper body muscle everyday i go to the gym, as i only go Mondays, wednesday and fridays, he said doing each muscle once a week, he said it will take years to see improvement and thats why i dont want to follow these plans.

Please guys i need some serious help as everybody says different things and it gets confusing.
REMEMBER- I want to get my upperbody fairly big, i dont want to be competeing in competitions so i dont want to get huge and do my whole body. Please help me with some valid suggestions.
thanks

Starting Strength.

Training only for upper body strength is about as useful as purchasing a car without an engine (even moreso at the beginner level).

Your legs are part of your body too, remember?

but why is that. ill just have a big upper body and not lower body, it doesnt mean i wont build uptop just because im not working on my lower body tho.

Squats, and Leg Extensions (Both lower body) can definitely add alot of size and gain to you.

If i were you id switch up your days so

Day 01: Chest
Day 02: Legs
Day 03: Arms
Day 04: Shoulders
Day 05: Back

Then lift heavy, low reps. But make sure to get started at about 50% of max weight first.
Concentrate on precision deadlifts, squats, bench, military, and eat 4-6 meals a day with lots of calories.
You'll make great gains.

Big upper body + Small legs = A frickin stupid look.

A good legs program will have big effects on your upper body growth.

Also, just because it worked for your brother doesn't mean it will work for you!!!!
