I share your dislike of doing that, if you can deal with the lower back load then go for it.
Watching the video again... are you flaring your elbows a little? They should be close-ish to your sides.
1 arm dumbell rows...if you have access to dbels heavy enough. Cabel rows like you said.
I majorly hurt my back doing BOR's last year...was sore for long time and still dodgy now. BOR's dont really put your body in a good position especially when getting heavy, 100kg+. I try stick to cable and Db rows now.
I love BORS, but as said, I find it ends up pumping my lower back as I go quite horizontal...I will have a play though.
Usually do BOR's and 1ADBR's anyway
Isn't it your gym day today Delvis?
BORs are something I want to incorporate into my training, just need to get the form right. In the past I had too much load on my lower back but I think that was down to form. The video I posted may not be as horizontal as I'd like, but the load wasn't on my lower back. Also helps having a strong core.
I'll be posting a video up on Tuesday of my next BOR attempt, which will be heavy. If done correctly then the lower back shouldn't be loaded heavily.
