Povetkin wasn't even sweating after his run. All Wlad has here is size. Povetkin clearly is more skilled. Siill>Size.
Really wouldn't be shocked if he can throw up 400lbs. He certainly doesn't work out with that weight, but for a 245lb man to bench 400lbs really isn't a stretch.
He's not strong. But then again he's not training for maximal strength. But still, those lifts are pedestrian at best and that's being generous.
