So you may or may not know this, but I was on the powerlifting team in college. Was I good at it? Not really? Did I still smash heavy things? Yes and it was sick.
There are lots of crazy things you do: lift stones, pull cars, etc. (not in competition but we all wanted to be on World's Strongest Man).
With that said, I'd never think about doing something as crazy as this guy.
He's bench pressing... with ice... ON THE ICE.
As much as I'd want to fall through and get frostbite, I think I'm good. No thanks.
