Cailer has pulled at least 881 conventional. These are weights that are hard to believe and seem almost impossible for a guy his size. A few years ago few would have believed these feats are even possible. The sumo pulls are insane as well, if you look at his stance, no suit, hook grip and no belt either.
Tom Martin is another impressive puller, I think he coaches Cailer.
Lamar Gant - IIRC is still the only Man to pull 5x his body weight !!!!
300kg 660lbs At 60kg 132lbs body weight back in the late 70s or early 80s
Phenomenal lifting - that said he had a somewhat strange physical structure,
He deadlifted in the Narrow Stance “Conventional” Style.
