I do them Ronnie style, bb stuck in one corner and pulling with a parallel, close grip handle, with the body at about 60 - 70o
Terrific exercise
I agree. I loved doing them this way, compared to the manufactured version with one end attached to a fixed end, that's on a platform you're standing on.
I never used 45's when doing the rows stuck in the corner-I preferred 25's for better ROM, and I think my best on that was 7-6 plates prior to my back going south.
On the aforementioned T-Bar Row, I think I've used 4 45's, and on a supported T-Bar, I remember going up to 5 for a good 6 reps.
Nothing spectacular....
