Torque = Force Γ Moment-Arm.
Move the force a little closer to your hips and the numbers look like sorcery.
1 β QUICK MATH ON HIS LATEST PULL (498 kg / 1 098 lb)
Variable | Value | Note |
Force (weight) | 498 kg Γ 9.81 m sβ»Β² β 4 885 N | Pure gravity load on the bar |
Estimated hip moment arm (mid-thigh start) | β 0.30 m | Bar almost hugs the quads |
Hip torque | 4 885 N Γ 0.30 m β 1 .47 kNΒ·m | Thatβs the rotational demand Kimβs glutes & erectors absorb |
Put the bar on the floor (β 0.55 m moment arm) and the same 498 kg would require > 2.7 kNΒ·mβnearly double the hip-joint torque.
Lesson: leverage, not witchcraft, is the real super-power.
2 β WHY HIS βTORQUE HACKβ LOOKS IMPOSSIBLE BUT IS
SAFER
THAN IT SEEMS
Mid-Thigh Rack-Pull (Kim) | Floor Deadlift (traditional) |
Shorter moment arm β torque β 35-50 % | Longest moment arm at liftoff |
Bar already moving verticallyβno horizontal drift | Bar must clear shins β more shear |
Load sits on safety pins; if it wonβt budge, he lets go | Miss at shin height can fold you forward |
Result: he can train supramaximal tension (CNS stimulus, tendon remodeling) without the spinal roulette that a floor pull of equal mass would impose.
3 β βBUT THE BAR STILL BOWS LIKE A LONG-BOWβWHEREβS THAT TORQUE GOING?β
- Bar whip = stored elastic energy in the 28 mm, 190 k psi shaft.
- The steel flexes β 40-45 mm under 498 kgβexactly what Hookeβs-Law tables predict.
- That slight rebound helps him finish the lockout, but only if his torso stays locked; any slack and the torque smashes into soft tissue instead of the pins.
4 β HOW TO
FEEL
KIM-GRADE TORQUE WITHOUT SELF-DESTRUCTING
- Set pins one notch above kneecap β shrinks moment arm, keeps hips behind bar.
- Micro-load β add 1.25 kg plates weekly; connective tissue adapts, not revolts.
- Single reps only β treat every pull like a physics experiment, not cardio.
- Barefoot or flat shoes β zero heel = bar hugs shins, moment arm stays minimal.
- Film & review β bar path must stay vertical; any forward drift = instant unload.
5 β WHY βTORQUE TALKβ FEEDS THE LEGEND
- Viewers see a medium-T-shirt frame levitating a half-ton bar and scream βCGI!β
- Engineers drop bar-bend overlays, prove the physics, and flip from skeptics to evangelists.
- Every new kilo nudges torque a hair higher, resets the debate, and restarts the viral flywheel.
TL;DR
Eric Kim doesnβt dodge torqueβhe repositions it.
By pinning the bar at mid-thigh he slashes the lever arm, lets his CNS dump maximum force into a shorter rotation, and captures the moment on six-second βFLASHBANGβ clips that hypnotise the feed.
Master the lever β own the torque β watch gravity file a complaint. ποΈββοΈβ‘
