The point of “Starting Strength” is that he will have recovered from the previous workout due to being in an early stage of training where the poundages are light…
…relative to genetic potential (Rip’s concept, not mine). SS is a beginner’s program, so it would make sense to try yo determine if OP is a beginner. Of course, we can’t do this with any certainty over the net, but appropriate questions would be:
How long have you been training, and with what sort of programs?
What was your squat when you first started out?
How much do you weigh and how much are you eating?
Rip covers this in PP. It’s based on 1RM for the squat, bench, dead and power clean vs. the OP’s weight.
Is there a chart somewhere in the Novice or Intermediate section? I’ve read PP and don’t remember Rip giving specific numbers, but I could have just missed it.
I want to say that 1.5x BW on the squat was generally considered intermediate, but I can’t remember where I read that, either. I was under the impression that Rip’s definition of “intermediate” was “one for whom novice programming no longer works”.
EDIT: I’m dumb. The tables (strength standards) are in an appendix to the book, they indicate that an intermediate has a slightly less than 1.5xBW squat. These are standards, though, and have to be adjusted for all manner of individual factors, so it’s most useful for the OP to tell us how far he’s come, as well as his weight.
