My deadlift sucks, my max is 315 and I cannot seem to hit anything higher. Even with all the block pulls and deficit deadlifts and assistant work, I can't seem to get passed it.

Been wanting to find ways to increase it or at least a program that can take my PR to a new level.

I was looking for a new program and came across this: deadliftworkouts.com/coanphillipi-deadlift-routine-10-weeks-max-attempt/

Has anyone done the Coan routine? Can't find much testimonies on it.
