That dude is strong, all the way strong dude.
Something like that, yes. We had a set of two cable lat pull down bench in Gold's Gym Helsinki, one with a 300lb stack, one with a 500lb stack, both made by Kraftwerk. He used just that heavy one, because 300lb was too light. Even that 500lb wasn't enough for him, so he load a pair of 45lb plates on it. In fact, he needed a pair of spotters to help him sit in the machine, because he was too light to just sit down. After we got him sitting, and he start to pull, first two inches came from arching the wide grip pulling handle, and only after that stack start to move. It was impossible to find a pulling handle which was strong enough to him to use. He bend several of those while training there. Same with barbells, there was few bars made from black iron, which were permanently bend after he got his squats done.
