how did you fup your back?
It is kind of a long story. About five years ago, I injured my back pretty severely doing bent over rows. It took me about a month to recover enough from that to train like I used to, but my lower back has never really been the same ever since. I injure it about three times a year ever since then.
This most recent time occurred due to several things- I moved apartments and was hence moving some very heavy boxes, etc. Then, I tweaked it further picking up heavy dumbbells for incline presses. The following day it got far worse when I was shooting pool. It has been about three weeks since then. I'm not really in pain any more, but it still feels vulnerable.
