I stopped doing barbell rows years ago, simply because it is such an awkward exercise, and when you do go up in weight, then your form gets all out of wack, plus there is a lot of strain on the lower back----talk about an injury waiting to happen.
So... I instead have been doing one arm dumbell rows, I feel absolutely NO STRAIN on my lower back, and I get results !!!
Rather than resting my arm on a bench, I use no bench at all, and rest my forearm on my lower thigh, and it is comfortable and works just fine (well, this exercise is never comfortable , as you all know it can take the breath out of you after a heavy set).
Typically I use around a 100 lb. dumbell for around 10 reps, and have worked up to a 130 lb. dumbell-----now that may not sound like a lot for some of you, but my form is excellent, I get a much better stretch, so I feel it in the muscle more, I am not constantly fighting my form and balance--and I feel no lower back strain or pressure on the lower back.
Since I use 100 lbs. for one arm, that would mean 200 lbs. on a barbell, but anytime I got up to that kind of weight, my form was terrible, and it was just not good.
I love the one arm dumbell rows, and so does my back !!! good luck
