Oh yeah. That moment when you're testing whether you can lift it. I know the feeling. I'm getting back to heavy DLs after lockdown, when the most I lifted for 2 months was 50kg.
My one rep max is 87.5kg. The other day (with my trainer's beady eye on me) I did 3 sets of 2 reps at 80kg. By the 3rd set, I was tired and only managed with good form by re-setting each time, rather than touching down & lifting straight up. I then went down to sets of 5 reps at 75kg. We're aiming for me to lift 100kg as my body loves DLs, but I'm just over 60, so it's taking a long time.
I'm finding that technique is the key. I still use my back too much when I get tired, instead of pushing my butt back and then squeezing up. And I'm aware when my back curves rather than staying flat (not a huge amount but enough to be noticed)
It takes time ... and little micro-conditions. I lose power as I tire. I'm a lark so best to lift heavy in the morning, but if I didn't have good sleep the night before, I feel it earlier & tire more easily than if I've had a good night.
Go back to get perfect technique. Try sets at maybe 75kg or 80kg which is heavy, but not too heavy, if your max 1rep is 92. and get the strength and the technique perfect. I tend to train at 70kg which is enough for it to feel heavy but not too heavy that I can't also concentrate on form.
The other thing is that it's a mind game. My trainer sets up the weights and I don't count the weight until after we've finished, and he doesn't tell me, because we both know I psyche myself out if I know it's really heavy. I'm coming to see why elite athletes all use sports psychologists!
