Eddie Hall pulling 1020 lbs / 463 kg:
One of my clients told me about this, but couldn't remember the name. One of my friends told me it was Eddie Hall tonight, so I looked it up.
That's a man who earns the "chikara" (力) kanji tattoed forwards and backwards on his body.
But if you want really freakish, there is always Lamar Gant - 634 pulled at 123 pounds bodyweight. Equally freaky, in terms of weight and build. Long arms = short lift for the deadlift.
