I’m having a little difficulty with the shoulder press at the later reps. If I’m doing sets of 8, the first 5 are no problem. However, on six and up I start getting some sort of a shoulder blockage after the bar clears the head. I resolve it by kind of flaring/shrugging action of the left elbow/shoulder. I’m not really sure why this happens at the later sets as the technique in my mind stays the same. What’s the solution here, drop the weight? Consciously focus on shrugging? If I should focus on shrugging more, at what point should this be?
If what you’re describing is that you can’t lock-out the lift at the top, I’d lower the weight until you can perform the full movement for the prescribed number of reps & RPE.
