In pound-for-pound terms it’s not a strong lift.
Seven-plus raw pressing is so out on the edge of human strength in 2019 that “pound-for-pound”
analysis isn’t even a consideration.
Greater bodyweight and increasing strength output isn’t symmetrically linear.
As in the automotive world: greater and greater horsepower is required to achieve smaller and smaller bumps in speed.
Against 700 pounds, 400 isn’t considerable.
All five (FIVE) men who’ve moved seven or more have been very high 300s or into the 400s.
One day perhaps a low 300s man might punch out over seven, but in even contemplating the huge requirement of sheer counterbalance in extreme brench pressing, this boggles.
(Legless big pressers are strapped to the bench, I’m quite certain.)
