It's a great exercise for the lats.
I feel them more the old school way Arnold and Franco did them fully bent over on a block or a bench more than the now 45 degree way Yates did them. Now every one is doing the 45 degree back way. Maybe I never gave them a full chance.
Do them facing the back of an incline bench, you can change the angles and hit the back way better than standing.
I wonder if a cambered bar would work for that?
