In '82@123,Lamar Gant deadlifted 5.18x bodyweight. This WR still stands. (Iirc)
In '88@132, he DL'd 5.17x BW. This also still stands. (Iirc)
The '82 DL's the longest-standing WR in powerlifting, one of the longest in sports.
Truly the two greatest deadlifts lb for lb ever, all the more amazing for being 6yrs apart.
Though the huge poundages that some of the previously mentioned are mind boggling
That a human body can lift such amounts regardless of body weight.
