posterior delt exercises?

[XrCYST]

I'm trying to round my shoulders and need to hit the posterior delts. What exercises are good for this.

Standing reverse cable flyes are my favorite for this right now. I also like also 1 arm dumbbell flyes lying on my side on a bench.

Bent over laterals. Or sit at a low row pulley, attach rope handles, grip with thumbs up and pull up to your forehead, louis simmons style.

Reverse bent flyes

Standing reverse Flyes. Bend at 90 degrees, resting your head on somthing solid.
Then with arms pointed at th ground , lift up like you are opening a cellar door. As high as possible. Then close doors slowly on the way down, and blast up again. Nothing should move on your body, except arms. 3 sets to failure.
