That's right Why do you think I mentioned it? I know big strong men with horseshoes chiseled out of their upper arms would never consider a wussy ass exercise like a kickback.
But if you've got fucked up shoulders you gotta do what you gotta do I mean, if you're going for pure power, one thing, but you wouldn't be too focused on isolation movements then, anyway. If you're going for definition, then there's nothing wrong with it IMO.
why does that make a differance? definition comes from low BF not your choice of exercise...
personally if I had shoulder issues I would do pushdowns, overhead extensions and/or skullcrushers if they felt ok
they are all single joint movements that you can go relatively heavy on when compared to kickbacks...
