I love starting with Millpress, 2 warmup sets and then 5x5.
Lateral raises with cables, 4 sets, 8-12 reps, adding 5 lbs each set till you're barely doing 6 on last set.
Then some heavy barbell shrugs, 4 sets, 10-16 reps, squeeze like hell at the top.
Rear delt flies, 4 sets, 8-12 reps, superset these with dumbbell front raises holding the dumbell as if you're doing hammercurl
Deadlift, 2 warmup, 5x5 (burns the shit out of your traps!)
Dumbbell shrugs with 2 big dumbbells, make em touch infront of you, lean slightly forward and do 4 sets 10-12 reps. This makes the back part of your traps sore as hell.
Standing Rows - 4 sets, 10-12 sets
Seated mill press with slightly wider grip(on the machine, in a power rack or smith) 3 sets 8-12 reps
I don't do any dumbbell press, and haven't for many weeks. Coincidentally, I've stopped injuring my shoulder, and my shoulders are still growing
