I'm currently doing 5/3/1 and while I'd like to do simple overhead barbell press, I can't because of pain in my shoulders. I've gotten over an impingement (mostly, at least) and ever since, my ROM is severely reduced it seems for overhead presses. With BB presses, it's hard for me to start the exercise - meaning, picking the weight up off the rack and lifting it from my chest - which is why I use the Smith Machine.
Currently my range of motion is to the bottom of my chin, which equates to my upper arm being parallel to the floor and my forearm being perfectly perpendicular to the floor. So, I go from a 90 degree angle to full extension and back. If I go lower then my chin the stress makes my shoulders ache extremely bad - the the point where just doing the bar is a bit of a struggle.
Should I just soldier on, and start with the bar and full range of motion or should I accept my limitation?
Another point - I've found that when I do overhead dumbbell press (my accessory exercise - I changed it for full range of motion) I have full range of motion.
