I also had very personal and very painful experience with a frozen shoulder. Even now, after surgery and great range of motion, you will not see me do an upright row and a lateral raise truly out to the side. I am careful with overhead presses. I also avoid (and tell my clients) to reach to the backseat of the car to retrieve anything. When traveling, I have a rollerboard with 4 wheels so that I do not need to pull it behind me.
