Agree here.
Anything over 8-10 reps I no longer consider to be "heavy".
I usually keep my SLDLs in the 8-12 rep range. Anymore than that and I'm only using like 135 pounds, and the only thing that gets accomplished is soreness.
Doing a ton of reps, to me, isn't really any safer. As fatigue sets in, form can suffer. I've done a few sets of 50 rep squats in the past, and after the 20th one, I'm gassed and my form looks awful. That's when people get hurt.
3-5 reps is safer than 20 any day on a compound lift IMO.
