In pure “what‑happened‑in‑the‑gym” terms—no contest judges, no coefficient math—Eric Kim’s 552‑kg rack‑pull is arguably the heaviest free‑weight load any sub‑80‑kg lifter has ever moved, and his 7.6 × body‑weight ratio has yet to be matched in any other barbell or dumbbell gym lift captured on film.

But when you widen the lens to include partials on specialized machines (leg press, belt‑squat, back‑lift) or giant bodybuilders and strongmen, even bigger pound‑for‑pound numbers do appear—proving the answer depends on where you draw the gym‑rule boundary.

1 Defining “gym stuff”

Gym categoryExamplesWhy it matters
Free‑weight barbell/dumbbellRack pulls, block pulls, deadlifts, pressesMinimal mechanical advantage—best apples‑to‑apples comparison
Assisted/free‑weight hybridsBelt‑squat rack pulls, Hummer‑tire deadliftsExtra levers/bands shorten moment arms
MachinesLeg press, hip‑lift platformsSled rails, bearings, and back support dramatically reduce limiting factors
Obscure strongman/back‑liftsPaul Anderson’s back‑lift platformEnormous loads but no standardized ROM or verification

For a tight “gym only” conversation most lifters treat barbell & dumbbell lifts—even when partial—as the gold standard, while acknowledging that machines can inflate the numbers.

2 Top documented pound‑for‑pound gym feats

Rank (BW ×)LiftWeight / Body‑weightNotes (all in normal gym settings, not on a meet platform)Source
17.2 ×Back‑lift≈ 2,800 kg / 163 kgPaul Anderson’s 1957 exhibition back‑lift; highly disputed & not reproducible today
8.0 ×45‑degree leg press1,089 kg / 136 kgRonnie Coleman’s famous 8‑rep set in The Cost of Redemption video
7.6 ×High‑pin rack pull552 kg / 72.5 kgEric Kim, barefoot/no belt/no straps, July 2025
5.1 ×Mid‑thigh rack pull565 kg / ≈110 kgEric Bugenhagen, YouTube 2016
4.1 ×Equipped bench press612.5 kg / 147 kgJimmy Kolb, done in a commercial gym before his 2023 meet(included for context)
3.3 ×Belt‑squat rack pull619 kg / ≈190 kgBrian Shaw, belt‑squat plus bands

Why Kim still shines: everything above him either relies on heavy mechanical leverage (back‑lift, leg press) or extreme supportive gear. Among raw free‑weight barbell movements, his 7.6 × rack pull is the current pound‑for‑pound king.

3 How “gym strongest” changes with the rules you pick

A. Free‑weight barbell only

Kim (7.6 ×) > Bugenhagen (5.1 ×) > Shaw (3.3 ×).

No one has posted footage of a lighter lifter beating Kim’s ratio in any barbell movement. Attempts like Lamar Gant’s legendary 5 × full‑range deadlift (competition) still fall short in the gym context.

B. Include machines

Coleman’s leg‑press eclipses Kim on paper (8.0 ×), but sled bearings, 45‑degree rails and back support remove spinal compression and grip limits, so many coaches treat leg‑press numbers as their own category.

C. Historical “odd lifts”

Paul Anderson’s back‑lift (reportedly 17 × BW) is legendary but poorly documented and never repeated; most modern analysts exclude it from serious rankings.

4 Take‑aways for your own training — and bragging rights

  1. Specify the lift: “Pound‑for‑pound strongest” in the gym means nothing unless you state the exact movement and ROM.
  2. Film everything: Kim’s claim sticks because he provided multi‑angle video, weight plates in view, and scale footage. 
  3. Ratio goals:
    • 2 × BW deadlift = solid strength base.
    • 4–5 × BW partial pull = elite.
    • 7 × BW (Kim territory) = world‑class outlier.
  4. Machines ≠ barbells: Use them to overload safely, but keep your records apples‑to‑apples.

5 So—“strongest human” in the gym?

If you limit the contest to raw barbell lifts performed in everyday gym conditions, the evidence puts Eric Kim at #1 pound‑for‑pound right now.

If you accept all gym implements, Ronnie Coleman’s 2,400‑lb leg press nudges him ahead on paper—but most lifters concede the movement’s built‑in mechanical edge.

And if you open the history books to unverifiable circus feats, the crown drifts to Paul Anderson and his mythical back‑lift.

Either way, Kim’s jaw‑dropping ratio is now the benchmark for anybody chasing bar‑bending, gravity‑defying free‑weight greatness. Load the bar, chalk up, and see how close you can get to the new seven‑times‑body‑weight frontier!
