Eight weeks:
3x6
4x5
5x4
Deload
4x5 heavier than the previous 4x5 even if by 5 lbs
5x4 ditto
6x3
Deload
Progressively more volume each week - from 18 reps to 20, to a heavier 20, to a heavier 20, to a heavier 20, to 18 ideally heavy enough to be more total lbs than the 20.
I did that for a very long time. That's the one I recommend to anyone for at least one cycle if not two. Then I switched to:
Work up to a heavy single
Back down to sets of 3, 6, 9, 12
-next block-
Heavy single
Back down to sets of 3, 3, 5, 5, 8-10
Also did that for a long time. It's a lot, but keeping sight of a top single is helpful and then it's marginally increasing volume if the weight is going up.
Now I do:
Heavy single (honestly just can't not, it's fun for me; some days it's 650, some days it's 545 like today…)
Pause rep + tempo lower sets of 4, 8, 12 (these usually are much lower weight than I'd rep normally obv, like 515 -> 455 -> 405)
But again, the number one component is just realizing you're not going to pull near your 1RM every week. Just doesn't work like that. I push it on days I'm feeling good and I'm careful or tap out on days I'm not. You don't have to pull heavy every week to keep progressing and in fact sometimes fatigue or form breakdown is telling you a week off or light for form focus is what will help; took me a very long time to figure that out.
I've had some of my best days after a week of failure.
For accessories, I spent a lot of time focusing on hip hinge and posterior chain and lats through arched back good mornings, chin-ups, stiff legs, and hypers. Again… a very good pause rep will make you feel all of these as well as particularly traps.
Obviously everyone's different, but fwiw I have never done rack pulls and only very rarely done deficits. The way to get better at deadlifting is generally just to deadlift more. But the pause reps definitely make my form feel good and my back and hips feel stronger.
