things Ive read over the years, thats why I asked the question, since I cant remember the original sources, but I did a quick google and found a few right off the bat, I snipped some info from them:

Upright row. Pulling weights, a barbell, or a weighted cabled bar up under your chin is a big no-no, says Saremi, a podiatrist and editorial staff member of the Aerobic and Fitness Association of America's American Fitness magazine. "When people pull their hands (carrying the weight) up to their chin, they are going to compress the nerves in the shoulder area, impinging the shoulder," Saremi says
snip2:Whereas this popular exercise is meant to work the deltoids and trapezius, in reality it is murder on your shoulders. It is performed by holding a loaded barbell or dumbbells at your waist with a close-hand grip and pulling the weight up, leading with the elbows, to just below the chin. In this position, the arms are bent at the elbow and then internally rotated, an action not usually harmful. Add resistance, though, and every time you raise the weights, the tendons in the shoulder become impinged -- or pinched -- by bones in the shoulder joint. That's going to hurt: Maybe not now, but somewhere down the line, tendon damage is almost a given.
snip3: Dips/Upright Row – the key mistake made with these exercises is allowing the shoulder to move beyond 90 degrees relative to a position parallel to the floor or perpendicular to the body. I always recommend stopping at 90 degrees to protect
the shoulder capsule and the rotator cuff.
