here is what I am doing, not sure it will work for you but who knows,im a firefighter and I need functional shoulder strength and with strength comes size.
Seated db press 4 sets 12
this next exercise I dont really have a name for but I take a barbell put one end in the t-bar row attachment on the power cage(you could stick it on a corner too) load up one end and then get it to shoulder height and do a one arm press with the bar. 5 sets 10-12
side laterals 5 sets 8-10
bent over laterals 5 sets 8-10
ive gotten quite strong on this routine and reccomend anyone try it for a change up,particularly the second exercise.
