The original title was "changing 531 assistence after 2 yrs to more hypertrophy-oriented, but was probably too long for the mods.
That's the problem, I've had really shitty period in my life lately, I drunk definitely too much and ate definitely too little and all my lifts went significantly down. I really liked them to at least get back where they were BUT as i said pushing doesn't matter for me that much and front of my body and arms are the places i lack muscle mass (it really looks like all my 90kg are in my back and thigs) so I could compromise strength gains in bench and press (to some degree) for some "vanity training" for those parts.
I always did chins between both military and bench sets (Wendler recommended this in first 531 manual), I don't see problem with that. But I also have to admit that I tried this with rows couple days ago and definitely felt weaker during my last bench set. If I'm going to do this I'm going to put chins in the bench day, and rows in the press day.
I often record myself, and after 2 years I think I'm starting to have decent form. Fact is that shoulder pains are less common since I started to concentrate on tucking elbows. As for injury, I think I might did something when I did 2 years of bodybuilding with really shitty technique and lot of benching (that was 7 years ago, but still.)
And I'm grateful for that. If I wanted be petted on my head and listen how awesome my training ideas are I would ask my girlfriend what she thinks not wrote here.
