yoo guys im looking to build some mass through my workout but my shoulders are lagging compared to the rest of my body due to an injury i had and couldnt really train then heavy for quite a long time.

for my shoulders i currently do this

DB shoulder press 3sets 10 8 6
Upright Row 3sets 10 8 6
Rear delt Fly 3set 10 8 6
superset DB side lateral raise with Barbell shurgs 3sets 12 10 8
DB arnies

i have been doing this for a while and think i need to change it up bcoz i have adapted to this any1 with any criticisms on this workout or if ye could advise me on a new workout all together it would be much appreciated cheers guys.
