i dont even think 5 in 45,000 average males could do 405 for 10, id say MAYBE 1 IN 100,000 or maybe even less, hell in 95 percent of gyms you wont see one legitmate 405 SINGLE in a year let alone 10 reps.
This. I do 320-330 in a good form for 7-8 reps and half of the gym are staring from the corners (another half pretend not to care lol).. Keep in mind - gus who are posting on bb'ing boards are serious bodybuilders, that's a small percentage, even tho' it may seem that "many" guys who bench crazy amounts are everywhere, when you read these boards. Irl - just in the most hardcore gyms you could see a good number of guys who can go above 320, hell, even above 260 is good.
My gym on a "hardcoreness" scale is like 7, and I'm one of the strongest there amongst like 120people. So one could calculate approx. statistics when it comes to "regular gym goers".
As for "regular joes", not even worth talkin' about. general people doesn't even dream about these weights, they doesn't even imagine what it is to handle a mere 225lb above their chest.
