Lol it’s Ed COAN - Conan was a badass fictional barbarian.
Duffin holds the Guinness World Record for weight lifted in the sumo deadlift regardless of gear, and he did it without a suit to boot.
No man in any amount of gear, at any bodyweight, and with or without straps has EVER pulled 1,003 from the floor except Duffin, and he nearly did 3 reps at that. Coan, Belkin, & Woolam are the best 220 Sumo pullers ever, no doubt. But the biggest pulls from floor belong to Duffin.
If you want to talk lords of grip, you should be looking at top Pro Strongmen like Jerry Pritchett demolishing 900lb frame carries up a ramp without straps.
Ed Coan is the coolest though. Got to shake his hand at the Olympia and he is so nice. And his hands are HUGE.
