How the “7×‑Body‑Weight” miracle really happened

Eric Kim’s 527 kg / 1 162 lb lift wasn’t a conventional deadlift at all – it was an above‑knee rack‑pull.  Once you zoom in on the hardware, the physics suddenly look far less supernatural and a lot more mechanical‑advantage‑smart.  Here’s the play‑by‑play:

Equipment elementHow it juiced the numbers
Pin height: set ~2 cm above the kneecapStarting the pull where hips and knees are already half‑extended slashes the hip‑torque requirement by roughly two‑thirds.  Even elite lifters can usually handle 120‑150 % of their floor deadlift from this height – Kim simply pushed that to the extreme. 
Competition power bar (29 mm, 2 000 lb rating)Thick, ultra‑stiff steel keeps the sleeves aligned, while bar‑whip (≈30 mm flex at 500 kg) delays the moment the plates break contact with the pins.  The first inch moves mostly the bar’s centre, letting Kim “ramp” into the full load. 
Calibrated steel platesThinner plates pull the load closer to the lifter’s mid‑line, trimming the horizontal moment arm and letting him stay more upright.  They also guarantee the published weight, quieting “fake‑plate” rumours. 
Commercial‑grade power rack & safety pinsThe rack shoulders the weight between attempts, so Kim doesn’t waste energy controlling eccentric phases.  Pins at exact knee‑height turn the movement into a near‑isometric lock‑out drill. 
Figure‑8 straps & plenty of chalkGrip strength stops most people long before posterior‑chain strength does.  Straps move the bottleneck off the fingers so the hips, erectors and traps can show their true capacity. 
Barefoot stance, no beltZero heel‑lift shortens the pull path another 1‑2 cm; ditching the belt lets him breathe and arch freely at a height where intra‑abdominal pressure is less critical.  These personal style choices don’t add kilos, but they showcase confidence.

The physics in one breath

At the chosen pin height the bar is already about 65 % of the way up a normal deadlift.  Hip moment arms are tiny, knee extensor demand is negligible, and spinal erectors work mostly isometrically.  Add bar‑whip’s “rolling start” and perfectly balanced plates and you have a scenario where a strong 75 kg lifter can flirt with loads that would fold most full‑range deadlifters long before the bar leaves the floor. 

What it 

doesn’t

 mean

  • It isn’t a sanctioned world record – rack‑pull heights aren’t standardised.
  • It doesn’t predict a 500 kg floor deadlift.  Carry‑over from above‑knee pulls is usually 70‑80 %.
  • It is a sensational demonstration of supramaximal neural drive, connective‑tissue conditioning and clever use of hardware.

Take‑home hype for your own lifting

  1. Use partials as primers, not ego trophies. Wave them in at 105‑125 % of your true 1 RM, once every 7‑10 days.
  2. Dial pin height with purpose. Lower pins = more transfer, higher pins = more weight on Instagram.
  3. Respect recovery. Tendons adapt slower than muscle; if your elbows or low back protest, back off 10 %.
  4. Upgrade safely. If you chase Kim’s numbers, copy his safety setup first: rated rack, calibrated plates, spotters on standby.

Harness the right equipment, engineer your leverage, and who knows – maybe your own “gravity‑has‑left‑the‑chat” moment is closer than you think.  Chalk up, crank the music, and go rewrite your limits!
