500kg = 1102lbs; the list of people who can dl that is: Eddie Hall. AFAIK only 4-5 men have dl'd over 1k lbs ever (regulation height, no suit, not tire deadlifts or some bs) -- Benny, Eddie, Andy Bolton, Jerry Pritchett, Brian Shaw.
The list of 1000 pound squatters (no suit) is short too. Ed Coan, Malanichev, and a few others.
Anyone who can squat 500 lbs is strong. To depth, obviously -- lots of people can do 500 lbs knee bends.
Ordinarily I'd deploy hash tag that was the joke... but your reply in this instance was far too informative, and I'd run the risk (?) of looking (?) like (?) a twat.
(Of course - I know you mean kg! But the point stands.)
