does he use the 'it was legal and the Dr gave me one dbol a day' lie?
400lb bench isnt bad for 220, but it was single ply which added 50lbs even back then.
you could read the dave tate/wendler advice but thats for equipped lifting.. trying to bench all tris doesnt really help much when yr a raw bencher. same as sitting back on a box squat, doesnt do shit for raw squatting that should be mostly quads anyway
either way his advice is all wrong for getting bigger. I used to bench 405 for reps, now I rarely go over 315 and my chest and arms are bigger, because I do the reps slower and do a ton more volume.
