165 is my PR. I haven't been squatting much since I've been having some hip and lower back issues. If I went and started squatting again today, I probably wouldn't have a problem starting at 125 for 5x5.
You shouldn't. Probably 90% of the little wuss frat boys at my old gym couldn't begin to do that. Anyway if you can do multiple sets of reps over your bodyweight that is really good.
150 lb to parallel, can comfortably do 3 sets of 10 or 5x5...need to increase the weight soon.....don't know what my 1 rep would be as I haven't tried...
