This may have been the breakthrough. 175 x 1 x 5, 185 x 1x 4, 190 x 1 x 3, kb cleans, floor pushups

 It dawned on my that I have been holding the weight with the wrong muscles in the rack. Too much tension in the arms and shoulders and not enough supporting the weight with the legs and trunk.Letting the weight sit on my torso, letting it SETTLE ,instead of trying to hold it above the torso

unrack it

LET IT SETTLE

WHAT A DIFFERENCE! Right from the  start. Whereas I usually start to feel too much left arm issues as soon as I get to 135 today there were NONE. Across all sets and reps! I unracked it and let the bar settle onto my body ( without relaxing OR flexing my legs) just supporting on my torso,

Then driving my chest up into the bar to initiate the press and then driving with the arms

Cant believe how great everything felt. Didn't even need to cinch the belt tight!

did kb cleans for the first time in a long time and they felt great( except for my wimpy forearm bones)
but these stay in
