MAN WTF. Super set..??

The reduced injury risk is a definite byproduct of doing pre-exhaustion techniques. But you don't see many use this because of just what you said above. You have to use less weight on the compound movement and that messes with one's ego.
We are so concerned with lifting more weight that we forget that isn't always the final goal of getting bigger.
Train smart for what your goals are. But that takes time and discipline.

Since I have a bum shoulder I will do very light super sets of dumbbell shoulder raises, lateral raises, tricep ext and reverse flys to warm up that whole shoulder girdle complex, before a heavy compound pressing movement. Not to prefatigue per say. But to stimulate the neurology and get some adrenaline released, to help prime that motor pattern required for pressing to increase force production and decrease injury risk.

I sometimes like to tweak thing a bit and I'll aim for a higher volume of reps say around 10-12. But I will utilize drop sets and lift weight I can only get up around 3-4 times. Drop weight then continue until I reach my max reps goal but using weight I wouldn't normally get those reps with. I think it just normal drop setting but rather doing 6-8 reps. I Go heavy sometimes. Cuz I don't like the low volume of rep when using heavy heavy weight so I get it in somehow though like that. Note the when I'm doing this. My goal reps will reduce alot cuz of the fatigue. I start with whatever weight I'm using and whatever I'm dropping it by and I get my goal reps at first but after all that volume. By the 2ND set I'm already down a few reps total on each drop set or super ETc.
