I am about to add bent-over rows to my routine and was looking on bodybuilding.com (http://www.bodybuilding.com/fun/exercises.php?Name=Bent+Over+Two-Dumbbell+Row) to ensure I had proper form. I looked through the variations before deciding to ask this so, I TRIED to research and answer it independantly. What I want to know is, if I set the bench @~45-60* and lean forward on it doing rows with my torso supported, would that negate the intention of the exercise? I want to know because I occassionally [sic] have lower back issues and fear this particular exercise with bring them on. Thank you in advance.
