In rugby there are a few good squatters and bench guys.
Owen Frank’s has a video of a 230kg squat at about 95-100kg body weight I think. And caims a 300kg squat.
There is an Irish prop that claims a 350kg squat. A few other props (imagine line men) claim 200kg benches.
However freak of nature Manu Tuilagi how plays out side centre a position where he covers a lot of ground (half running back half wide receiver) and is still credited with a 190kg bench.
Allen couldn’t bench more than 500 without multiple people touching the bar. He’s obviously a strong guy, but you gotta use some common sense here.
