That's wild. Upright rows bother my shoulders as well. Both barbell and dumbbell. Plus the barbell bother my wrists. Yet I am also fine with high pulls. I wonder if a lot of people are like that.
I wouldn't be surprised. I've seen upright rows on lists of dangerous exercises, omitted from exercise instruction books because it can hurt your shoulders, etc. But I've seen High Pulls recommended pretty much by everyone. My theory is that the Upright Row puts your shoulders into a mechanically poor position at the top - with the wrists bent, arms pulled down by the weight, tight to the chest. But a high pull uses more power, and the bar pretty much is weightless (or feels that way) at the top, where it hurts the most on an upright row. So I think that the top of the Upright Row is the painful position, but the High Pull gets around that by forcing you to apply that "top position" strength earlier to get the bar up, and then you just lower it (or drop it). My thought is that you don't really use the muscles in that disadvantageous position, but you still use the same muscles to get there. Same work (if not more), no pain.
I could be way wrong, I'm no expert. But that's how it seems to me.
I like the thrusters. That's definitely going into my next cut.
They're really good stuff. I found them here, glad one of my posts showed them to someone else. You don't even need so much weight on them, not if you're doing bunches in a metcon, to get lots of good work out of them.
