You rarely bench you act like you are such a expert you backing down from a challenge? I know.you have a camera.on your phone i will strict bench 255 for 2 i want to see all these things.you're talking about come into real world, this is why i hate arguing with people like you, you dont have the real world experience its all what you read online.
You went saying i dont go to the gym to backing out of a lifting contest.
I think body type plays a big factor in this, whats a wide bench for you might be narrow to someone else.
Personally my bench is shoulder width and my elbows are very tucked, i also drop the bar at about my sternum, i have tried the arch and i felt less solid on the bench.
I have no doubt that its a technique issue and if i could bench like a powerlifter that my bech would go up, but thats my point.
