Sorry I wasn't clear- and thanks for asking-
I was up to 240 on squats, getting quads just below horizontal, which is when I stalled. It had been hurting my lower back starting at around 210-220 and killing me at 240. I'm guessing the back pain was part of the stall, but who knows. I switched to ATG, and at the same time reset down to 200, as the ATGs were a bit tougher (experimented with a few sets to see exactly where I could reset down to and still hit a 3x5). I've been working my way back up, adding 10 lbs per session, and now I'm at 230. My back has been better since switching to ATG, but at around 220 I started leaning forward, and at 230 I'm really on my toes as soon as I come out of the bottom, especially on the third set. I can barely complete the third set of 5, for the last 3 sessions. I ike to get a strong third set before increasing the weight, but I went for 240 anyway, and almost had to ask for help and/or drop the bar on the rack bottom (which one is worse? ) during the first set.
