Good advice guys. Definitely try a wider grip. Possibly letting the bar down your back a little. If you do thou you will most likely have to slightly lean forward to keep your balance, and back arched. Even with the slight lean, your lower back will be in a better leverage position and will be Easier to use more poundage, legs capable providing. I always feel my back as the wea link and doing as I said lessens the pain lol. key here, definitely keep your elbows high, especially when coming outta the bottom, will help prevent bar from rolling further down your back. You will also prob haveta adjust your stance. Mines slightly wider than shoulder width and toes slightly out. lotta possibilities.
