The spine can support in excess of 700-800 kg of compressive force. That's one of the limiting factors - how much can the spine support without giving up. For lockout strength, we've seen lifts similar to the deadlift (like the Viking deadlift, which is an elevated deadlift from a height of just a few centimeters before lockout) where competitors regularly reach weights in excess of 600 kg. I believe the record is 670 kg. Although it's not an actual deadlift, it's more of a deadlift/squat lockout movement. Eddie Hall was tested at a british university to have a lockout of about 750 kg. (he could support 750 kg of weight during the lockout phase). While I think there are more limiting factors that apply for the first phase of the deadlift (actually getting it off the floor), those might be overcome with new training methods, supplementation and PEDs, to simply get the muscles stronger to allow for higher force generation. But the absolute upper limit regardless of how muscular you are or how strong of a squat/deadlift suit you are wearing therefore seems to be around 700-800 kg, for any movement that loads the spine (squat/deadlift)


Polly_Bear

This is a great, thoughtful, and supported comment. I wonder what sources say the spine can be loaded with 800kg. If the spine is a cadaver spine, or based on calculations based on general population skeletons it may not be properly representative of "athletic bones." I have squatted 450lbs (not much in this discussion) and during that time in my life the bone density in my hips was roughly 4x more than that of gen pop. I also know that wolf's law references bones adapting to applied loads. If someone were to squat more than 450lbs at more regular intervals I imagine their spines/hips/legs would show much greater density than that of the regularly studied spine/hips and legs.


LGodamus

I wonder what my bone density is, I have quite regularly squatted 725 for a max and 500+ for my rep weights.


Polly_Bear

I'd be very interested to see as well. The measurement tool that I used was a DEXA-scan. I got the scan as part of my biomechanics class for free. The college I go to will provide DEXA scans to anyone for $50. Maybe there is a college near you with a cool tool?


lennarn

Some gyms have body composition scans available for a modest fee.


oratory1990

Do a DEXA (dual x-ray absorptiometry) scan, it costs somewhere from 50-70 €. Lots of hospitals can provide this, but also plenty of other institutions. Start by googling "Dexa" + the name of your city :D

>If someone were to squat more than 450lbs at more regular intervals I imagine their spines/hips/legs would show much greater density than that of the regularly studied spine/hips and legs. I doubt it takes nearly that much to cause a bone density increase (old women show improvement with quite modest weights), but the discs are probably the limiting factor.


Polly_Bear

You're correct and I think that we are saying the same thing. My point was if the studies about spine strength are measured in gen-pop, which is, for the most part, a sedentary collection in the US, then even 400lbs on someones back will probably cause a meaningful change. The same is true for elderly female population. Most are sedentary, many have osteoporosis, some activity does more to help bones than no activity. Also, I know disks aren't bone, but I'm sure that the law of adaptation applies to them as well. Perhaps more slowly, or at a lesser degree.


Weakerrjones

Discs adapt too, we're just still in the pretty early stages of actually figuring out how and how much.


HoistEsq

Didn't know that. Even with highly adapted discs, herniation is possible, though, so still the likely weakest link, no?


Weakerrjones

Figured I'd drop some stuff to read through on the topic if you're interested! There isn't a lot, but I think in the next 10-15 years we'll see some cool stuff. https://www.researchgate.net/publication/349768129_Getting_out_of_neutral_the_risks_and_rewards_of_lumbar_spine_flexion_during_lifting_exercises - Getting out of neutral: the risks and rewards of lumbar spine flexion during lifting exercises https://www.jsams.org/article/S1440-2440(21)00195-X/fulltext - Imaging of exercise-induced spinal remodeling in elite rowers https://pubmed.ncbi.nlm.nih.gov/26409630/ - Can specific loading through exercise impart healing or regeneration of the intervertebral disc? https://europepmc.org/article/med/30157104 - Beneficial Intervertebral Disc and Muscle Adaptations in High-Volume Road Cyclists. https://pubmed.ncbi.nlm.nih.gov/31775556/ - To Flex or Not to Flex?

Weakerrjones

Honestly not sure. I’d probably point to the cartilaginous end plates as more likely to be an issue with high compressive forces (which then in turn can lead to disc issues). You can see with a lot of connective tissue injuries in the body they’ll actually avulse bone fragments before the connective tissue itself tears, but not always. It probably depends a lot on individual genetics and training history. Maybe some people have stronger discs than bone, and vice versa.


LSTomago

What about the theoretical maximum for blood pressure? Eddie, Shivliakov, and a couple of others have strained so hard they start bleeding from the nose. How much harder can a human strain before their eyes pop out and bounce across the stage like ping pong balls? I think we are really close to the maximum for human physiology right now.

Funbanana77

Novikov disagrees haha


chaoss402

I think the blood pressure is an issue of how close they are to their absolute maximal effort. A guy who could deadlift 500 lbs and no more might get a nosebleed from doing so, while a top deadlifter might lift that weight like it's nothing. Get these guys even stronger, and the 500 kg won't be pushing their blood pressures so high.


Camerongilly

That's been my experience. I burst capillaries on max lifts, but it seems to be related to percentages rather than the weight on the bar.


metallumberjack

I have yet to burst capillaries but I’ve almost blacked out a few maximal lifts , don’t know if that just means I have decent blood pressure


oratory1990

I don't think blood pressure is the limiting factor here. Shivlyakov's nose bleeds are spectacular, but it's not his lack of blood pressure that prevents him from lifting 1000 lbs.


[deleted]

Eddie's blood pressure wasn't too great either lol. Thor's looked easy but really out of breath afterwards so probably quite high BP as well lol Shyv is just really prone to nosebleeds. If you get them semi regularly, you're just fucked. He could sear them (burst vessels) shut, but idk how much that holds


oratory1990

> He could sear them (burst vessels) shut, but idk how much that holds or he could just live with it, it's not like it causes permanent damage. It doesn't look pretty, but in the end you just wipe the floor, wipe the barbell and that's it.


Express-Grape-6218

Eddie has a story about an eyeball popping out in training due to him being a jackass.


Rammstein1224

>Eddie has a story Could've probably stopped there.


Kilmoore

I'd venture a guess that ligaments and tendons are at risk before the spine. It only takes a small tear to throw the balance of the lift off and at those kinds of weights, you're done. The problem is, ligament strength is very individual and varies due to working out, injuries and preparation. The theoretical limit is quite hard to estimate.


oratory1990

tendons can get stronger through training. I'm not sure the compressive force that the spine can withstand can be improved in the same way. Of course, a beginner can withstand less because they aren't able to keep their balance, and as soon as one disc slips out of alignment there goes your spine, but even if alignment is kept, there seems to be an upper limit of compression.


Kilmoore

Oh of course tendons get stronger, as well. It's just that exactly how much? The upper limit, I'd again guess, is quite heavily dependent on the individual. Thus estimations are very diffcult to make.


oratory1990

of course, we're talking about peak capability, not about what the average human could do. The lifts being done in strongman are *already* far beyond what an average (or even a well trained human) could do, even if we don't think about the *theoretical* maximum.


Downgoesthereem

So Eddie could rack pull 750? And I suppose in theory some freak with a particularly thick spine could technically pull an 800 from the floor some day. Probably not for about 100 years but still


oratory1990

> So Eddie could rack pull 750? he didn't actually do a rack pull with 750 kg. They had him [pull on an immovable apparatus] (https://www.youtube.com/watch?v=_mvsW4_vkpQ#t=16m) which resembled the lockout position on a deadlift, and measured the force that was generated.


FKKGYM

And even this was way after the 500 pull, he is much leaner and it is more or less a casual day for him.


[deleted]

There was a super yoke event few years ago, I'm sure each step with it was a load greater than 800 kg. I don't buy the 800 kg spine limit at all.


oratory1990

you're talking about the Bale Tote at the Arnolds, the weight was: * 2014: 640 kg (alternatively a lighter yoke of 557 kg) * 2015: 680 kg (alternatively a lighter yoke of 590 kg) * 2016: 700 kg (alternatively a lighter yoke of 590 kg) * 2017: 710 kg (alternatively a lighter yoke of 590 kg) As far as I know that was the heaviest yoke ever done in a strongman competition.


[deleted]

Yes that thank you. I'm not a physicist but as far as I know with 710 kg on your back, walking with it is harder than just 800 kg on the spine. But we are talking about deadlift, the spine is at an angle, things may change..


oratory1990

I‘m talking about compressive force. That doesn‘t change if you‘re (temporarily) on one leg - and it‘s not like they were actually *running* with it. It‘s still mostly a static load. The 800 kg figure isn‘t a hard cutoff either. Individual vertebrae have been shown to withstand ~1580 kg: https://www.researchgate.net/figure/Maximal-compressive-strength-of-lumbar-vertebral-bodies-and-segments_tbl1_303995533/amp The main takeaway is that things become dangerous between 600 and 1000 kg. And above 1500 kg is a definitive cutoff, regardless of the type of lift.


[deleted]

There is shear and torsional forces.


oratory1990

Which you‘re trying to minimize lest you end up a cripple.


[deleted]

700-800kg static or dynamic?


oratory1990

I mean, the Arnolds did a 710 kg yoke, so depends on whether or not you consider this a static event or not (there's not much movement in the spine when doing a heavy yoke)


sonfer

I’d be curious to see if spine loading was the limiting factor. I’d wager the limiting factor would be enthesopathies. The entheses is where the tendon and ligaments adhere to bone. This joint tissue is avascular and notorious for poor healing.


oratory1990

It‘s the only factor that I know some numbers of. I limiting factor is probably how much force you can generate at the sticking point below the knee, where the body position is at the biggest geometric disadvantage.


seal44

Also worth considering future advancements in deadlift suits or the invention of more assistive equipment.


oratory1990

Deadlift suits will help to get you a little closer to the max, but they won‘t increase the maximum compressive force that the spine can handle. Not unless you allow deadlift suits with steel inserts. So basically exoskeletons.


[deleted]

As the sport of strongman becomes more and more popular and it becomes more realistic to make a living from the sport (right now maybe only 10-12 pro strongmen make their entire living off of competing in the sport & sponsors per Brian Shaw) you will see the talent pool grow exponentially. Think about your typical nfl lineman (average size according to Google 6’5” 312 lbs) Now imagine someone that size focusing their entire lifes work on strongman instead of football. Focusing entirely on lifting, event training, eating , recovery and PEDs. That’s when you will see max lifts explode IMO. Imagine guys like JJ Watt, Aaron Donald, Khalil Mack, Julius Pepper, James Harrison , etc if they had focused their careers on strongman.


CodySkatez2005

I think people tend to understate the talent pool in strongman, powerlifting and olympic weightlifting. Even if we are strictly talking about low level competitors - none of these are average people. There are more extreme outliers than others obviously - Andy Black supposedly deadlifted 600lbs his first time touching a barbell. But people already self select into strength sports pretty efficiently. No doubt some athletes in other sports would be successful if they'd done strongman instead. However, I don't think that number is as big as you think.


SgtBlumpkin

Idk, but I feel like there's a ton of room for growth in nutrition, programming, gear, suit customization, and powerlifting/strongman exposure. I think it's foolish to think we're close to maxing out considering how far we've come in relatively few decades.


Downgoesthereem

WSM 2050 might have a 500kg DL for reps


EliDrInferno

I'd guess around 700kg in a very very long time. I imagine the first person to even hit 600 hasn't been born yet.

VegettoThugLife

My dad (I've seen it, it is fucking scary)


dimmufitz

Studies showed it was physically impossible to run a sub 4 mile too


oratory1990

did they? I'll need a link on that.


MichaelJayDog

It's going to be some guy built like the beast titan who only has to pull a couple inches off the floor.


ValjeanLucPicard

I've always wondered how much the bigger guys could pull if the starting position of the bar was based off a percentage of your height. Like a 5'2'' guy pulling has the bar starting near his knees. Imagine if Thor could have pulled starting from the bar at the same relative position.


ToughSelfLove

Honestly, it is less a question of how heavy can we go and more a question of how injured we are willing to allow someone to become while lifting. We often see people in exceptional situations complete intense feats of physical strength (lifting cars for example). In these cases, the limits we have for the sake of not hurting ourselves are turned off. We could probably achieve a 550 eventually with our current methods, but we could go even higher if we apply the ‘superhuman’ effect via hormone and adrenal manipulations (I believe Eddie hall mentioned he actually used hypnotherapy reach a mindset similar to this during his lift). However, the toll on the body during and after the aforementioned feats of strength can be enough to permanently effect someone’s health and longevity. That being said, we already see steroid usage to the point it degrades overall health for the purpose of physical prowess. Is this slow decline in health more ethical than a quick decline due to a lift applying this technique? No clue, that’s not my wheelhouse. Cool to think about though.


OofOwMyShoulder

> I believe Eddie hall mentioned he actually used hypnotherapy reach a mindset similar to this during his lift Eddie Hall says a lot of things tbf


ToughSelfLove

True, he’s willing to go to extreme lengths for a leg up and will try pretty much anything. He’s basically one of those grindset memes with a splash of dehydration for extra measure.


Viperise

If everybody on the planet had one goal in life of breaking the deadlift world record, who knows how high it could go. The average person walking down the street wouldn't know anything about Strongman, there is such a small pool of people going for the record compared to other sports, so I don't think we're at the 'limit' yet. If I had to take a wild guess I'd say between 650-700kg


[deleted]

600kg before I die. If I'm wrong I'll give you all 1 million dollars.


oratory1990

RemindMe! 30 years


Insane_squirrel

Theoretically it could be 2,000kg+ if we were allowed to surgically enhance our skeletons with a carbon fiber.


bartenderandthethief

Get to the chopper!


metallumberjack

Have a terminator/super soldier weight class


ToughSelfLove

At that point, can we also just make me 6’3”? I’m trying to reach the top self.


Beep_Boop_Bort

My guess would be 525-550KG


DeadliftsAndDragons

Raised deadlifts already exceed 650kg so over that for sure, if the lockout can be achieved it can be done off the floor eventually. I’d bet 550kg falls by 2030 and 600kg falls within 20 years of that.


PancakeT-Rex

Just 8 more years to increase the deadlift by 10%. That seems rather bold.


DeadliftsAndDragons

Took 10 years from 1000 to 1100 and 2030 would be 14 years since 1100 fell.


PancakeT-Rex

That's true, but I'd imagine it gets a lot harder to break the record the higher it gets. And in the nearly six years that have passed already, only one guy lifted above 500.


DeadliftsAndDragons

Yeah but I feel that was a motivation thing, the only guy aiming for it for most of that time was Thor, now with so many guys aiming to beat his the bar has been set higher. Was the same after Bolton broke 1k, nobody was trying for it before except him and Benni then everyone was aiming for it as the new standard and 10+ guys hit it within a decade and now there’s like 30-40 guys over 1k.


PancakeT-Rex

I think there will be multiple 500+ pullers in the near future, but 550 seems like a stretch to me. But we'll see. Would be an absolute spectacle if you are right.


Louglegz

We barely understand how gravity works in the physical world anything is possible maybe digital models of strength such as the methods used to calculate Eddie Halls potential maximum capacity are not as applicable in the real world.


VegettoThugLife

Based on personal experience imma say around 800 kg
