And they are much smaller now than when competing in strongman.
Eddie Hall, WSM 2017. WR Deadlift 500kg
Hafthor Bjornsson, WSM 2081. *WR Deadlift 501 kg.
Eddie's was done in competition.. Hafthor's during Covid in his home gym as part of the World's Ultimate Strongman Feats of Strength series. There's a lot of debate about the realj record, given that it was outside of a normal competition environment. While I am no Hafthor fan, I will freely admit that his 501kg pull looked stronger, and took less out of him, than Eddie's 500kg pull.
