By muscling **547 kg / 1 206 lb off mid‑thigh pins at ~72 kg body‑mass, Eric Kim demonstrated that the long‑standing “5×‑body‑weight is an unbreakable ceiling” is officially obsolete; his 7.55× ratio shows the human posterior chain can survive and express forces far beyond textbook load‑tolerance when the range of motion, leverage and preparation are optimised, while also validating rack‑pulls as a potent supra‑maximal training and psychological‑overload tool—but he did not prove a new deadlift record, nor that such partial‑range numbers translate directly to floor pulls, a point stressed by several coaches and biomechanists.
