funny thing is I was doing 20 rep squats with about 170lbs and it wasn't really bothering my back at all, neither was the dead lifts at about 275lbs. But when I was doing those leg presses, I found that my ass would come off the seat just a bit at the bottom of the press and that's when I felt the surge of pain. I'm feeling better today, but definitely not good enough to get back in the gym. I'm going to hit shoulders tomorrow and then next week just slowly get back into it, slowly, I have to keep saying that SLOWLY.
thanks for all the support guys.
