Shoulder excercises

What are some good shoulder and shoulder blade excercises?

I have a smith type machine, dumbells (adjustable, and 10lb)

I want to work that since that’s the place my arm gets tired after throwing.

thanks for the help.

There yeah go…I usually do 20 reps for every exercise. I usually use 5 lb. dumbbells. Its not alot but you’ll feel it if you do two exercises back to back…it’ll burn.

Those are very comparable to the shoulder excercises i do.
