Hi all. I have been doing barbell rows bent at nearly 90 degrees to the floor. While I have had good results from this technique (in terms of upper back recruitment as far as I can tell)my weights have stayed fairly low. While this in itself doesn't concern me, I seemed to get a better workout when i tried a 45 degree strict row with heavier weight.
The 90 degree angle seems to hit the rear delts more. I do romanians or conventional deads following bent rows so my upper back gets pretty beat up. So increasing weights on the bent row is not my prime concern. Please give your opinion on the most effective technique to do it.
