I row with a body width grip, could do them with preset bars but they aren't heavy enough.
How many racks are there? I generally don't care what people do in the racks as long as they're not using it to do something like curls when other people are waiting.
It will be better long term for grip strength to work with the thicker and longer bar
I saw a guy on the lat pulldown today that a shrug would have a bigger ROM. I think the only reason the stack was moving was because he was going up and down off the seat pad. Maybe it was some kind of new age, gravity defying, reverse squat?
