I'll spend a day on deads. I start of light (135-185) from the ground and when I'm done with that I move to rack-partials with a decent amount of weight ( up to 505 or so)--
When I'm done with those I end up shrugging with as much weight as I possibly can from the pins. I've managed to shrug 14 plates, which is 675lbs. total and I might pull it around 6 to 8 inches for 2-3 short reps. Sometimes I just hang on to the bar for dear life until I drop it back on the pins. I have yet to 'max out'... don't wanna hurt anything.
I do wear a belt and use straps, etc.
By the time I'm done, I am DONE!
I consider "dead day" to be a whole body workout. I notice I even have D.O.M.S in my face muscles the next few days from grimacing or whatever you call it... hamstrings, low back, calves, neck, traps, forearms, biceps = all wasted.
So, yeah, 'back day" for me is definitely split up.
My next back workout would be something like weighted chins and low-pulley unilateral rows.
