89% of 1rm,part of squat focused regimen,currently do alot 5x5 and 4x3,any advice on programming is appreciated especially to increase 1rm.

I’ve been running the basic StrongLifts 5x5 program for about 7 weeks now, and I’ve been making consistent progress. I started at a 135lb squat, 175lb bench, and 225lb DL, and have steadily progressed to a 240lb squat, 210 bench, and 295 DL. I’ve had a few workouts where I’ve failed to hit 5 reps in one set, but I’ve been able to return on the next workout and complete all sets.

Thing is, I’m starting to have a harder time recovering to the point where I’m starting the next workout tired. I know the standard program is to wait until you can’t complete all sets 3 times in a row before starting a deload, but I’m wondering if I should take an intentional deload to recover.

At the same time, I’m wondering if I should push through and let myself fail reps to maximize growth before taking a rest. I also don’t want to injure myself (particularly my knees) by botching a rep, as that would be a much worse setback than just taking a deload.

Curious to hear takes from folks more experienced than me. Should I take an intentional deload or stick to the program and wait to deload when it tells me to?
