You know I got 425 right
...with a tweaked shoulder.
I know what your issue is...and it ain't mental. Back in the day I would max 450 (natty) after a pretty decent workout. If you reduce your total chest sets and lower your rep range some...you'll get what your looking for. You'll have enough power to blast past any mark you set.
*Try this
Warm up with a few sets of pushups (10-20)
Do some shoulder dislocation mobility stretches. (3 sets of 5-10)
Get on the bench....bench 225, then 315, then your 385 max, after that, put on 4 plates and bench that turd. (Only do this on max day)
After that the do your chest workout. Your killing yourself with the extra stuff on max day.
If you think it's mental, then imagine THAT weight is about to fall on your most precious thing in life...you know what I mean.
Stop bullshitting....I need you to join me into the 5's
Edit: powerlifters don't do a complete workout before they compete. I might be wrong though.
