I literally meant, instead of:
Deloaded Rows
185x7, 180x7, 175x8, 145x10
For the last set of 10, what you called the hypertrophy" one, switch to one-arm dumbells, or cable rows (I didn't mean the chest had to always be literally supported), bench supported rows, head-supported rows (cressey..I don't like them personally but that's only because of my neck problem), etc.., so on.
I also like to do rows from different angles, etc..like high-low pulley rows, or low-high. Basically I find that a large rowing variety is friendly to the shoulders. You already have face-pulls and to me that counts as a rowing variety as well. Hell the the other day I just did a bunch of standing rows with a band for a different flavor (that was in addition to heavier rowing before). Given, though, I do a TON of pulling as compared to most people.
You know the whole deloaded row thing is a tool like anything else. The making it the be all and end all started with the propaganda of a relatively few people, and all of them associated
As far as lower back endurance, a non deloaded barbell row would seem to adress that better, imho.
