[300zx TT]

i am 18 yrs old and as of now i bench 225 lbs so i was wondering if anyone could give me like some machines or different types of sets n reps to do to help me improve my upper body strength and apparence. Since the only time i have to work out everyday is in school i am limited to just 1 hour but i only have 3 weeks left of school so i am going to go to a bigger gym with more machines so i need some tips on a ritual workout some of you do since the only thing i have been doing in my gym class is a lot benching and dumb bell benching. I mainly want bigger traps and a thicker neck but the main part i want to improve is my chest it seems as much as i train in machines that work out the pecs only the upper part of my chest are strong n firm but the lower part of my pecs are very flabby ...i am like 5.8 feet tall and weight 155lbs recommend anything?
