I did Starting Strength for about 8 months, back when I was still newer to lifting. Was able to get my squat from 155 lbs for 5 reps to 335 for 1, and my deadlift went from 185 for 5 reps to 375 for 2 reps. My upper body did pretty much nothing though. Only reason I even did SS was because a few posters on here told me too.
I will say, my legs have been pretty strong (relatively speaking) ever since, even after 2 major surgeries and a long time off. Squatting 3x a week starting out will help there I guess.
From a bodybuilding prospective, it really needs to be tweaked a good amount to even be considered being followed. Pretty much no upper body work outside of bench and military press.
If I could do it over, I would not have done SS. I think there are better beginner programs if your goal is a balanced physique.
