shoulders/traps - clean and press also works out the traps, forearms, biceps, triceps, and upper back
back - deadlifts wide and narrow, nothing better for thickness and if you alternate the technique doing elevated, rack, and wide deadlifts you can really hit every part of the body...
legs - like the deadlift its a total body workout
chest - flat bench press ( close grip middle chest , wide grip outer pec, neck presses upper pec's)
arms- hammer curls (recruits some shoulder, traps, forearms, and biceps)
triceps - dips (also recruits lower chest, delts, and triceps)
what if for example instead of doing
4 sets of incline, 4 sets of decline, 4 sets of flat or whatever
you would do 8-12 sets of regular flat bench going from 15 reps-2 reps
would you gain quality mass ?
same thing applies for each muscle group with listed exercise's
