Preface: about three weeks into StrongLifts, I’m going up in weight but am curious about a couple things. Advice is highly appreciated

  1. should I count bad form as a “failed” set and remain the same weight for the next week? (Ex. My last few sets of squats don’t seem to be as low and I have a harder time with keeping my lower back straight)

  2. my bench is only 15lbs lighter than my squat this doesn’t seem like it should be the case. What do I make of this?
