Workout from today went way better with 130kg. But I realized that my upper back would relax too much and for some reason I'd rotate the elbows, bar moves lower compared to normal rep, destabilizes and goes a bit forward and messes up the whole movement. After I really concentrated on firm upper back I didn't get any elbow rotation, but when fatigue kicks in it comes back and the looser upper back is visible.
I guess shoulders/bar moving forward, because of elbow rotation, is enough to severely mess up the movement.
I can see the last rep of the first set got messed up and the elbow rotation was the worst, while on first three reps it was nonexistent.
