I hope the image I attached is visible. You should see that, in my 9th week (not counting deload) and progress on 3 of the 4 lifts is amazing, but bench is very flat. I think I might know the problem, but looking for advice.
I should mention I am 45 (5'8'', 220lbs) so age could certainly be a limiter here, either in gains or recovery. Been lifting (typical 5*5 stuff) for a year before starting 5-3-1.
I may be doing to much. Doing BBB variation 1, so after my 5/3/1 and my 5x10's, I typically pick 2 exercises, and do 3x8 of each. Usually pick from Wide-bench, Close-grip, DB flies, DB bench, incline - something related to benching.
I also think my triceps may be the limiter.
So now I plan to just pick 1 exercise for the 3*8's, and have it be something more tricep focused : closegrip, pin press, skullcrushers etc.
Was my original plan wrong? The same approach is working for the other 3 lifts, obviously, so just not sure.
