I never liked that exercise. Sometimes I think they say to bring the barbell to your stomach, I don't know I think it's a pretty crappy exercise either way. I don't think it does your lower back any good though it helps to rest your head on something I think. Bent arm pullovers on a machine or leg curl bench is probably the best lat developer IMO. I do like seated rows though and I do them a lot. I do them with the bench press unit of my home gym with a little padded board that I rest my chest against and the board rests against the leg press arm with foot rest removed. But that probably helps nobody unless you have the same kind of machine. :um
