why so many rotator cuff injuries on here?

i posted earlier, but what is a rotator cuff exercise?

I do not know what they are called, but most involve shoulder rotation with the elbow at a ninety degree angle. An example would be laying on your side with a dumbell in you hand. Arm against your side, rotating the dumbell from your stomach up until your arm is parallel with the floor.

what about stretches for it?
