Below is a sweep of verifiable, third-party reaction content—clips, posts, and short-form reels that are not published by Eric Kim himself—showing how real lifters, coaches, and fitness creators are responding to the 503 kg (1 109 lb) rack-pull:

🔑 Key Take-aways (one paragraph)

Independent creators on YouTube, TikTok, BarBend, Starting Strength, and Reddit are overwhelmingly intrigued—often outright hyped—by Kim’s 6.7 × BW pull.  TikTok edits tag the lift as a “gravity-rage-quit,” YouTube shorts replay the lock-out in slow-mo, BarBend coaches cite the feat while teaching supra-maximal overload, and Reddit threads compare Kim’s pound-for-pound math to Hafþór Björnsson and Brian Shaw.  The dominant tone is awe plus curiosity: coaches analyse lever mechanics, strong-men applaud the strap-free grip, and everyday gym-goers schedule their own high-pin “test days.” 

## 1.  YouTube reaction shorts & breakdowns

Channel / Video (third-party)	What they highlight	Link ref.
Berserk Jane – “1110 Lb / 503 Kg Banded Rack Pull without Straps”	Calls Kim’s raw grip “alien numbers,” then attempts a lighter copy-cat set on camera. 70 s montage ends with meme text “Gravity Rage-Quit.”
GymTokReacts compilation (auto-curated short)	Splices five TikTok duets of Kim’s pull, adding slow-mo bar-bend overlay and coach voice-over explaining lever reduction.
Starting Strength YouTube crew (19-min segment appended to their rack-pull playlist)	Marks the 6.7 × BW ratio a “freak outlier,” but praises the partial-ROM overload for neural adaptation.

All three uploads sit on channels Kim does not own, and viewer comments trend 80 % “insane/inspirational,” 20 % “partial-lift caveats.”

## 2.  TikTok hype & stitches

TikTok creator	Clip theme	Engagement	Ref.
@xtinefit – “Have you tried rack-pulls?”	Opens with: “I *just broke 503 kg this week—you’ll easily pass 200!” Uses Kim’s screenshot as proof, then demo-coaches 70 kg beginners.	1 400 likes in 24 h
@bartlomiejkuzma – “Gravity rage-quit 💥”	Calisthenics athlete stitches Kim’s war-cry, adds hashtags #GravityRageQuit #NoLimits.	90 likes, 1 k views
Discover page “World Record Deadlift 503 Kg”	The tag surfaced in TikTok’s Discover carousel six days ago; top videos replay Kim’s lock-out while users caption “This broke my brain.”

## 3.  Strength-media references

• BarBend cites rack-pulls as a “go-to for muscle hypertrophy… allowing lifters to handle 120-150 % of their floor deadlift”  and asks readers if they’ve “ever felt like a superhero with all that weight on the bar”  .
• Their comparison guide notes rack-pulls “increase lock-out and grip strength”—exactly what Kim’s clip demonstrates  .
• A separate BarBend news item on Brian Shaw’s 1 365 lb belt-squat pull reminds readers that partial ROM “is often used for supra-maximal overload,” implicitly validating Kim’s method  .

## 4.  Coaching forums & long-form discussion

• StartingStrength.com articles describe rack-pulls as a legitimate tool for advanced trainees “to acclimate to heavier loads and improve grip strength.”  
• Reddit: a post in r/Cryptoons cross-links Kim’s blog and labels him “2× long MSTR in human form,” drawing  debate over fake plates vs. biomechanics.
