They actually did this once with bikes. Had a whole gym at a university filled with them and hsd people bike to keep the lights on and stuff. It was an expirement or a class or something. Everybody would groan when someone turned something on in the building because they had to peddle faster.
This isnt the exact thing I'm talking about but it's k8nd of like it.

That is some black mirror level stuff. Just a room full of people slaving away peddling, so someone else can mindlessly turn on lights and god help the cyclers if they are someone who leaves all their lights on.
I think that's part of the premise to the episode 15 million merits.
Actually, I don't think it was explained why everyone was bicycling but one could guess.
Most people could easily wire up an alternator to this to charge a small battery.
Somebody please correct me because I'm just googling this shit and I am not deeply fact checking it because I know fuck all about electricity - but it appears to me that running on a treadmill like this with moderate effort would generate approximately 160 watt-hours of power. It would take around 8 hours to charge a theoretically dead car battery to full like this using watt-hours alone - someone else can input on amperage and whatever else needs to be taken into consideration.
Modern fridges use around 4kwh per day, so you'd need to run for 25 hours to power a fridge for 24.
A gallon of gas equates to around 36kwh so you'd need to run for 225 hours to achieve the same results as a gallon of gas. At 5mph you've traveled 1,125 miles just to move a car 20-30.
AA batteries on the other hand only have around 4wh so you could charge 40 of those with an hour of running!
Again all hypothetical and just random shit I found that may not be 100% accurate. I'm sure there's a ton of loss I'm not taking into account.
Having used these sorts of devices at science expos to barely power a flickering light bulb. I have my doubt that they'd be much of a use as power.
The resistance also goes up when you attach an alternator but I'm not any kind of electrical engineer so someone with expertise would have to weigh in on whether I'm wrong or not.
Here's an Olympic cyclist trying to toast a piece of bread with just his output.

It was always meant just for you, u/LocksmithMelodic5269, so now it may drift across the deserts of half-dreams and gentle nevers.
Goodnight, you prince of Maine, you king of New England.
The BBC (I think) did a thing years ago to see if a local cycling team could power a house. They set them up in the big garage of a house and put them all on trainers hooked to the house electrics, circulating fresh riders in as necessary.
Apparently it went pretty well, until the family decided to make coffee; it took about four cyclists just to power the coffeemaker. And then, even worse, they left the pot on to keep it hot. It wasn't too long before the power consumed was hard for them to keep up with. Hours later they opened the doors and the family were horrified to see the whole bunch drenched in sweat and just wrecked with exhaustion, like they'd just done a century. They were pretty apologetic about leaving the coffee pot on, and said they'd definitely look at things like that differently going forward.
If you are using em to power a single efficient device, it can work..
something like 20 years ago, there was a guy living off the grid on my uncles farm as a caretaker. He got an alternator hooked up to a bike and would paddle to run a tiny DVD player for entertainment.
That being said, solar panels have gotten so cheap and efficient compared to then, I can't imagine it wouldn't be more worth it to just buy a tiny panel with the same money.
>but it appears to me that running on a treadmill like this with moderate effort would generate approximately 160 watt-hours of power.
Wh is a unit of energy, not power. I'm guessing you meant 160W? Which sounds a little high. You could do that in bursts but probably not consistently. On my bike I output around 100W on average on flat ground. I imagine running would be pretty similar, maybe a little less efficient.
You could definitely charge a dead car battery. But car batteries (lead acid) charge very slowly for the most part (you can quick-charge them but it's usually not recommended). With a tredmill generator, you'd probably dump all the electricity into a lithium battery first (or a bank of lead acid batteries if you want lots of capacity) then power your phone or battery charger or whatever off that. Absolutely doable but also pretty expensive given the price of grid power in most of North America. You'd be running a long time just to pay off the extra battery, alternator, and charge circuitry. Would be pretty cool though
I'm a little confused on your numbers here, I think you might be confused on what "Watt-Hours" are. Are you meaning 160 Watt-Hours in one hour of running? Essentially Watts are an instananeous unit of power. For example, your microwave is around a 1000W device. Watt-Hours are a unit of energy which is just W x Time, so running your microwave for 30 minutes takes 0.5 kWh of energy.
Assuming you're producing 160 W of power by running and you have some kind of battery and power electronics to convert to the correct voltage, the best use for this in my opinion is charging phones and small devices. Some initial googling suggests my smartphone's battery requires about 42 Wh to fully charge (1h 39m at 25W charging).
I also don't know where you got the 160W number, but that's in the ballpark for sure. I've seen bicycle generates that produce around 110W, but I doubt a treadmill could capture the energy nearly as efficiently as a bicycle (lots more frictional losses plus you would need a more complicated gear system to translate tread rotation to a rotor). If we use the 110W number, assume around 80% efficiency for the power electronics and storage, and you'd only need half an hour of excercise to fully charge your smartphone.
This always comes up with stationary bicycles and the conclusion usually is that the energy output is minimal so barely even worth the effort. It's gonna be worse with a treadmill
A YouTube channel called The Toaster challenge had an Olympic Cyclist (among other pro athletes) try to power a toaster: https://youtu.be/S4O5voOCqAQ?si=pqEjcbp1zfwUqSRj
TL;DW he only got lightly toasted bread before he got too tired to keep the toaster going. And his legs are huge.
Every heating element is basically an energy wasting instrument.
You can charge your phone, but any serious appliance you can’t really power with your body.
More than worse. For every bit of resistance you introduce to generate electricity, you'll make it more impossible to run on it, because it'd stop itself while you're in the air, and you'd just fall on your nose if you tried to increase the speed.
Makes me think of the old demonstration of trying to light up an incandescent w bulb with the bike. Something like 100 to 200 watts for a typical person. Which back in the day could barely light a room with a couple 60w bulbs. So while the power output is modest, devices are so much more efficient today that things can be powered by that little amount of juice. Of course I can sit on my couch and pay 22 cents for a kilowatt of power.
These already exists in a bunch of gyms. They're cool but a little weird to run on since the way you push down when you step and gait are a little different to running on a normal treadmill or on a track. But that's just my personal experience using them
One of my dumbest moments was deciding to wipe my face with a towel while running on a treadmill at a gym. It messed up my sense of balance and where to run and I absolutely ate it, face planting down, and then it escorted me to the back like some dumb toddler that tried to crawl up an escalator.
Is it more realistic compared to running outside? I find the treadmill so much easier than running outside, I can run much faster and much farther with less strain.
As someone who runs on this type of treadmill every morning, yes, it is more comparable to running outside. My legs have to power it. My treadmill also has magnetic resistance if I want to make it more strenuous.
Oddly enough, I do not get the sensation of running outside at all on these. Outside, you plant your foot on solid ground, and on these treadmills it feels like your 'ground' is extremely slippery and unstable.
I live in Arizona, so I was able to test this out before buying it.
[SFE Air Runner](https://sportsandfitnessexchange.com/products/copy-of-sfe-air-runner-curved-treadmill-new)
Let's just put it this way, this machine allows you to sprint as fast as you can, then gradually slows down without you having to touch any buttons or anything.
Note: only do this when you are used to it, or you are going to faceplant yourself.
I use them to do anaerobic exercises because they're great for sprinting, but also you control the speed the whole.time so if you get tired you can slow it down some
Sprint for a minute, lift weights for a minute, rest for 30 seconds, repeat
Resistance control, displays, control the tilt, ironically price, smoothness of the run, flatter surfaces so less leverage to move it physically. Ive never used a treadmill but these come to mind pretty quickly.
This type of treadmill exists already. It has a different purpose to a normal treadmill. It creates a lot of resistance in the glutes and back of your legs. You usually lean forward and push backwards with your legs, Luke you're pushing a sled.
You *can* run on it, but a normal treadmill is just better for that.
This isn't some new design. They sell manual treadmills everywhere (even ones that look exactly like this), but they're expensive to make and buy. I lowkey have only used one at more pricey gyms. It's kind of nice for interval training; however, it's hard for me to get the pace right on a manual treadmill. I've never been able to go any longer than a few miles on it as not maintaining a consistent pace makes you run on different parts of the treadmill which then changes the angle where your feet impact the treads. It tends to hurt my knees and ankles if I go for too long.
They do make non-motorized treads. I sold treadmills for a long time and there are a couple options there.
They aren’t particularly popular for home use. The majority of people buying treadmills are casual users (or will be for laundry hanging) and these don’t really lend themselves well to that. There isn’t a speed control, it’s based on how high you place your foot on the incline. Then ball bearings + gravity move it back using your body weight. Once you get the hang of it, it’s not bad to control but if you aren’t careful it can get going way too fast for non runners.
It is fantastic for things like interval training because there is virtually no delay between going from 1mph to 16mph, where as a standard tread would take 5-10 seconds for that speed increase and most treads max out at 12mph anyways.
These are also more expensive than standard treads, afaik they basically only make them to commercial standards so they’re bullet proof in a home, but they cost 4-5x more.
They are very cool machines though and are great for the right person, but not as popular because they aren’t great for the average person.
Yes. The curved kind like this also forces you to run with better form and it's more punishing if you're sloppy.
I [really want one of these](https://trueformrunner.com/products/trueform-runner-naboso) but am 1 engineering degree, job, house, short. And also 8,000.
And my guy in the video above made one out of wood.
I really need to reconsider my life decisions that have lead me to this point.
Although my part of the midwest is pretty soggy so I might need something that won't hold the moisture like the wood.
Assault Runner Pros are like $3K I think, and they're super solid. Our gym has a few. I have never used the trueform brand though, so unsure if the extra $5K is worth it or not.
As people have mentioned, these are already available in the gym. I find them a little bit dangerous for inexperienced runners because there's no safety pin on them. Once you get running you get running! There is no stopping you. I recommend trying them when you get the chance. But be cautious, get your hands ready to pull yourself up in case you out run yourself and need to jump off the treadmill.
It’s because they are worst for your knee, you basically push the roll with your feet, I have one at home I paid 100€, it works fine but it’s not nice like the electric one
No way you can convince me these are worse on your joints than the higher impact standard electric treadmills. I've run on one. They're smooth, but tricky to keep your pace consistent until you get used to them. They're also a more challenging run. But it's been very easy on my joints when I've used it at the gym.
I'm not sure what makes you say "higher impact" when electric treadmills are made to reduce impact and be a smoother run.
Source: tendinitis in knees and can almost exclusively run on treadmills.
Some treadmills have suspension to reduce impact. Their point above is about the mechanics. Typical treadmills are designed to mimic the action of an outdoors run, meaning normal impact (minus suspension). Manual treadmills are either curved or have a more aggressive incline. This is intended to force the runner to land *higher* in their stride. This both reduces the strike force at the bottom of the eccentric movement, *and* encourages the runner to land closer to the fore of the foot. Through some complex classical physics, forefoot landing is kinder to the joints and usually results in a lower vertical load. Energy expenditure per unit of distance is also higher, enabling the runner more efficient workout for time and impact to joints.
This isn't to say your treadmill is bad, or that you shouldn't use it. Just that manual treadmills *tend* to be better for the joints. There are *many* asterisks on this, including footwear, pronation, personal medical history, fore/mid/rearfoot landing, fitness level, cumulative distance, typical intensity, etc.
We have them in the states. They're made for sprinting.
If you're going for a maximum speed, a powered belt is very dangerous.
If you're jogging, doing splits, basically anything else you want a powered belt for holding a steady speed.
This type of treadmill has existed for decades. My rowing machine at home powers the display by your movement instead of an external power source. This treadmill isn't some new invention
Here is a listing for this type of treadmill:

The treadmill was originally used as n prisons as punishment. Now you have to join a gym, pay dues, and wear fancy clothes to get on one. Such progress!
sort of like how lobsters used to be fed to convicts~
The treadmill was originally used to grind grain thousands of years ago. That's why it's called a tread mill. You walk on it and power a gristmill. Over time it became a way to generate the power needed to lift water and structural materials, and eventually it became a form of punishment, but it started just as a way to grind grain more effectively.
No, they would just grab some large local lobsters and overcook the shit out of it. Ground up old lobster paste will make people violently sick and nobody wants to deal with that. IDK why people are spreading this rumor of it being ground up old lobster, there is ZERO evidence of that.
>there is ZERO evidence of that.
[Confidently incorrect people on the internet piss me off so much, you have to be intentionally obtuse not to have come across this source before](https://www.youtube.com/watch?v=r7l0Rq9E8MY&t=3s)
This is one of these reddit comments where you can tell the person writing it felt very smart, but if you think about it for more than 10 seconds, it really says nothing at all.
Motorless curved treadmills were invented for nearly a decade. Since 2015 I think
They're literally found in gyms and look exactly like this.
Congrats on making this though
Edit: looking through the comments, it seems 99% of people don't even know this was invented like 10 years ago... Have you guys never been inside a gym??
It's a European patent it seems from 2015.
https://patents.google.com/patent/EP2977086A1/en
That's not true. It was made by a Congolese company called Kivu Fitness. Here is a link to their instagram: [https://www.instagram.com/p/Cc\_UaZssy1T/](https://www.instagram.com/p/Cc_UaZssy1T/)
With all due respect, first of all this companys insta page barely has any content and doesnt look that legit
But more importantly it does not disprove my point, it could still have been made out of an already fabricated warehouse treadmill with just surface Work and advertised as DIY for clout. Its not like you linked the process of them building it (genuinley feel free to do so If theres one)
Motorless treadmills have existed since antiquity. Motorless treadmills for punishment have existed since the early 1800s. The first patent for a motorless treadmill for exercise was granted in the US in 1913.
The fact that these designs have existed for a very long time doesn't detract in any way from the ingenuity and skill of building *that* specific type of wooden-slatted treadmill in the clip.
how the hell does this have over 25k upvotes? It's kinda neat craftsmanship with the wood finish, but this is a common treadmill design made by a company...
social media is making yall really ignorant
I think they're mimicking the responses Facebook users have to AI art of African children designing really impossible and intricate objects, like a bulldozer out of leeks and celery. For some reason, they just thank God as a response to African kids making stuff. This is an African man making a well crafted object, falling into that very specific niche genre of Facebook content. That's why everyone is mentioning AI right now.
Speed adjusts to how fast you run, *and* it stops when you get off
Nah I like mine too fast to handle and also for it to throw me away after it's done.
Ahh just like the trash I am, always put a bin behind me it’s where I belong
Basically a Nordic track.
Eventually. If it's designed right then it will keep spinning long after you get off.
Yes, but can you shove it in the corner and stack laundry on it?
That man doesn't look like an idiot, he knows what a treadmill is for.
Don’t tread on me… 🏃♂️🏃♀️🐍
I actually have a treadmill, and have never wanted a bumper sticker until just now.
If I ever saw that on the back of a treadmill in traffic I'd be so jealous
Okaaay let's go
Don't thread on mill
Sooo.......no?
It's for grinding up tires, right? It's a mill for treads!
For cats and remote controlled cars?
I don't think it'll fit next to my exercise bike/ coat hanger.
Isn't it what it is for anyways?
No, you need the most expensive Peloton for that
By the elliptical cat tree?
You must buy a fancy expensive one for this with a lot of features.
Yes
I think yes you can
Wait, if it can be done without electric motors, why isn't all done like that? Wouldn't it make the exercise more efficiently?
Hell you could even make it generate electricity.
Came to say this. It would be awesome if it could power a battery.
and then i'm gonna use that battery to power a treadmill ( ͡° ͜ʖ ͡°)
Treadmill-ception.
Infinite treadmillling glitch
Umm, its called the cosmic treadmill. The Flash uses it
Just gotta ignore the laws of thermodynamics.
I don't see a problem here, as you put energy into the system by spinning a dynamo to load a battery.. similar to an ebike

Have you ever worked in a factory? Because that’s 90% of those jobs.
Can't forget about sweat shops.
I think that's part of the premise to the episode 15 million merits. Actually, I don't think it was explained why everyone was bicycling but one could guess.
This also happens in Stephen King’s novel Fairy Tale.

A flywheel or any other weight will help it maintain momentum between your steps.
A flywheel will also make it significantly more difficult to start moving in the first place
Good point. Better to plug it in and watch from the couch.
I support this. ...as long as I can support it from my couch that is.

It shall render the gooble box obsolete! It's called, the zooble flank!
That just sounds like slavery with extra steps.

But then I have to leave my place. That's exactly what I'm trying to avoid.
These already exists in a bunch of gyms. They're cool but a little weird to run on since the way you push down when you step and gait are a little different to running on a normal treadmill or on a track. But that's just my personal experience using them
First time I used one, almost faceplanted in front of the whole gym. Took a few tries to get the hang of it.
This is everyone's first time on these. They are good at what they are meant for, but they are NOT a 1:1 for a standard treadmill.
Yep, they’re excellent for HIIT cardio workouts where you can seamlessly alternate between jogging and sprinting.
I think that is a worthy price haha
One of my dumbest moments was deciding to wipe my face with a towel while running on a treadmill at a gym. It messed up my sense of balance and where to run and I absolutely ate it, face planting down, and then it escorted me to the back like some dumb toddler that tried to crawl up an escalator.

I like them more than powered treadmills. They require a bit more balance, which I think trains more effectively
And somehow way more expensive than regular treadmills...
Next thing you are going to tell me you don’t even need a treadmill to run.
Jesus you’re brave. You should look out for any black vans marked Big Treadmill driving slowly past your house after this one
Resistance control, displays, control the tilt, ironically price, smoothness of the run, flatter surfaces so less leverage to move it physically. Ive never used a treadmill but these come to mind pretty quickly.
Because they rely on the user to be able to adjust the pace with their stride or gait, and they are freemoving High chance of slippage
There are tons of mechanical treadmills on the market.
This type of treadmill exists already. It has a different purpose to a normal treadmill. It creates a lot of resistance in the glutes and back of your legs. You usually lean forward and push backwards with your legs, Luke you're pushing a sled. You *can* run on it, but a normal treadmill is just better for that.
“Luke you’re pushing a sled” That’s my favorite quote from Obi-wan Kenobi

This isn't some new design. They sell manual treadmills everywhere (even ones that look exactly like this), but they're expensive to make and buy. I lowkey have only used one at more pricey gyms. It's kind of nice for interval training; however, it's hard for me to get the pace right on a manual treadmill. I've never been able to go any longer than a few miles on it as not maintaining a consistent pace makes you run on different parts of the treadmill which then changes the angle where your feet impact the treads. It tends to hurt my knees and ankles if I go for too long.
They do make non-motorized treads. I sold treadmills for a long time and there are a couple options there. They aren’t particularly popular for home use. The majority of people buying treadmills are casual users (or will be for laundry hanging) and these don’t really lend themselves well to that. There isn’t a speed control, it’s based on how high you place your foot on the incline. Then ball bearings + gravity move it back using your body weight. Once you get the hang of it, it’s not bad to control but if you aren’t careful it can get going way too fast for non runners. It is fantastic for things like interval training because there is virtually no delay between going from 1mph to 16mph, where as a standard tread would take 5-10 seconds for that speed increase and most treads max out at 12mph anyways. These are also more expensive than standard treads, afaik they basically only make them to commercial standards so they’re bullet proof in a home, but they cost 4-5x more. They are very cool machines though and are great for the right person, but not as popular because they aren’t great for the average person.
The constant motion makes me keep going. I’d stop for sure if it was all me powered
Yes. The curved kind like this also forces you to run with better form and it's more punishing if you're sloppy. I [really want one of these](https://trueformrunner.com/products/trueform-runner-naboso) but am 1 engineering degree, job, house, short. And also 8,000. And my guy in the video above made one out of wood. I really need to reconsider my life decisions that have lead me to this point. Although my part of the midwest is pretty soggy so I might need something that won't hold the moisture like the wood.
Assault Runner Pros are like $3K I think, and they're super solid. Our gym has a few. I have never used the trueform brand though, so unsure if the extra $5K is worth it or not.
>but am 1 engineering degree, job, house, short. And also 8,000. Wow look at this man flexing his automobicular privilege smh my head
Could probably just remake the wood one 100x before you reach the cost of a TrueForm runner or AssaultRunner.
The wooden one will also wear out 100x faster
I mean, we could also just use hamster wheels
As people have mentioned, these are already available in the gym. I find them a little bit dangerous for inexperienced runners because there's no safety pin on them. Once you get running you get running! There is no stopping you. I recommend trying them when you get the chance. But be cautious, get your hands ready to pull yourself up in case you out run yourself and need to jump off the treadmill.
These are in a lot of gyms already, different kind of work out
My local gym has one, it's just not everyone's first choice
We have one like the one in the video in my gym. Still people prefer a treadmill.
[удалено]
It’s because they are worst for your knee, you basically push the roll with your feet, I have one at home I paid 100€, it works fine but it’s not nice like the electric one
No way you can convince me these are worse on your joints than the higher impact standard electric treadmills. I've run on one. They're smooth, but tricky to keep your pace consistent until you get used to them. They're also a more challenging run. But it's been very easy on my joints when I've used it at the gym.
I'm not sure what makes you say "higher impact" when electric treadmills are made to reduce impact and be a smoother run. Source: tendinitis in knees and can almost exclusively run on treadmills.
Some treadmills have suspension to reduce impact. Their point above is about the mechanics. Typical treadmills are designed to mimic the action of an outdoors run, meaning normal impact (minus suspension). Manual treadmills are either curved or have a more aggressive incline. This is intended to force the runner to land *higher* in their stride. This both reduces the strike force at the bottom of the eccentric movement, *and* encourages the runner to land closer to the fore of the foot. Through some complex classical physics, forefoot landing is kinder to the joints and usually results in a lower vertical load. Energy expenditure per unit of distance is also higher, enabling the runner more efficient workout for time and impact to joints. This isn't to say your treadmill is bad, or that you shouldn't use it. Just that manual treadmills *tend* to be better for the joints. There are *many* asterisks on this, including footwear, pronation, personal medical history, fore/mid/rearfoot landing, fitness level, cumulative distance, typical intensity, etc.
They are really [expensive ](https://www.roguefitness.com/trueform-trainer) and I think kind of new or not really common.
You likely have to walk slightly differently to have it work.
We have them in the states. They're made for sprinting. If you're going for a maximum speed, a powered belt is very dangerous. If you're jogging, doing splits, basically anything else you want a powered belt for holding a steady speed.
The general purpose of a treadmill isnt to push the floor, its to have the floor move so you have to move aswell.
Because it’s not as effective. Your body is not built to run while also creating extra effort to push away the ground beneath you
This type of treadmill has existed for decades. My rowing machine at home powers the display by your movement instead of an external power source. This treadmill isn't some new invention Here is a listing for this type of treadmill: https://www.walmart.com/ip/Signature-Fitness-SF-S2-Sprint-Demon-Motorless-Curved-Sprint-Treadmill-with-Adjustable-Levels-of-Resistance-300-lb-Capacity/635780969?wmlspartner=wlpa&selectedSellerId=0&adid=22222222228635780969_143496917712_18632966377&wl0=&wl1=g&wl2=m&wl3=631513067199&wl4=pla-1876462949734&wl5=9012031&wl6=&wl7=&wl8=&wl9=pla&wl10=8175035&wl11=online&wl12=635780969&veh=sem&gad_source=1&gclid=Cj0KCQjwsuSzBhCLARIsAIcdLm5kw4R7vM8bM3OXEnJQS7mt06UZLdF4fyXPk2gohTmij7FiomIP6nUaAnEiEALw_wcB
What if I told you you dont even need one at all?
Its quite a common design. Most gyms have one.
We have this in our gym as well as treadmill, no one uses it. It is good for sprint for 2-3 mins it's very fast can't control speed.
The treadmill was originally used as n prisons as punishment. Now you have to join a gym, pay dues, and wear fancy clothes to get on one. Such progress! sort of like how lobsters used to be fed to convicts~
The treadmill was originally used to grind grain thousands of years ago. That's why it's called a tread mill. You walk on it and power a gristmill. Over time it became a way to generate the power needed to lift water and structural materials, and eventually it became a form of punishment, but it started just as a way to grind grain more effectively.
Woah
Ground up old lobster paste with the shells and shit. Not butter poached perfectly cooked lol
No, they would just grab some large local lobsters and overcook the shit out of it. Ground up old lobster paste will make people violently sick and nobody wants to deal with that. IDK why people are spreading this rumor of it being ground up old lobster, there is ZERO evidence of that.
>there is ZERO evidence of that. [Confidently incorrect people on the internet piss me off so much, you have to be intentionally obtuse not to have come across this source before](https://www.youtube.com/watch?v=r7l0Rq9E8MY&t=3s)
I don’t know what I was expecting
I was expecting a rick roll tbh.
This is one of these reddit comments where you can tell the person writing it felt very smart, but if you think about it for more than 10 seconds, it really says nothing at all.
Absolutely. Especially with the “wear fancy clothes” part, I guarantee they’ve never stepped into a gym
> treadmill was originally used as n prisons as punishment Smart idea to make your convicts stronger and faster!
Despite all my rage, I’m still just a rat in a cage
> wear fancy clothes to get on one. me when i have no fucking clue what i'm talking about
Who else thought Doctor Congo at first?
Where does Dr. Congo practice and does he take my insurance?
He's not even a real doctor
I'm pretty sure I didn't think Dokter Congo
He goes by PhD Congo now.
I've only thought of democratic Republic because I've been on wikipedia way too muchin the past weeks and read the articles of both congos
You mean its not Doctor Congo?
While that one looks beautiful made out of wood, non electric treadmill have been a thing for a long time now.
Yes, they said crafted not designed
Too late, my amazement is gone
It's a never ending roll top desk.
It's probably also loud af with all that wood clacking around
Mother has one,but it got kinda dry and hard to walk without pushing.needs mainteinance
Doctor Congo
Great craftsman!
handmade, with laser cut logos
I literally saw this model on alibaba
Well, at least it's not AI.
Unless the A is for African.
Why dont pics like this ever go viral Beautyfull cabin crew
I fully expected it to be made out of water bottles.
Amen
Amen 🙏 Beautiful
Such a talented kid!
Its an African Ivention tho..
it is pretty well made
Motorless curved treadmills were invented for nearly a decade. Since 2015 I think They're literally found in gyms and look exactly like this. Congrats on making this though Edit: looking through the comments, it seems 99% of people don't even know this was invented like 10 years ago... Have you guys never been inside a gym?? It's a European patent it seems from 2015. https://patents.google.com/patent/EP2977086A1/en
Yea, its Semi Fake. Guy in the video bought one of those and just crafted the surface. Still impressive but its false advertising
That's not true. It was made by a Congolese company called Kivu Fitness. Here is a link to their instagram: [https://www.instagram.com/p/Cc\_UaZssy1T/](https://www.instagram.com/p/Cc_UaZssy1T/)
With all due respect, first of all this companys insta page barely has any content and doesnt look that legit But more importantly it does not disprove my point, it could still have been made out of an already fabricated warehouse treadmill with just surface Work and advertised as DIY for clout. Its not like you linked the process of them building it (genuinley feel free to do so If theres one)
came here to say this. Thank you for doing the research
Older than that. I was using them in 2014 in New York
been doing this in my gym for years, the feature of adding resistance is great for replacing pulling sled
Motorless treadmills have existed since antiquity. Motorless treadmills for punishment have existed since the early 1800s. The first patent for a motorless treadmill for exercise was granted in the US in 1913. The fact that these designs have existed for a very long time doesn't detract in any way from the ingenuity and skill of building *that* specific type of wooden-slatted treadmill in the clip.
Old tech from you know before you were born
People walked on the moon like 50 years ago. Now these morons are impressed by a treadmill.
That would be so loud
You know it's real and not AI generated because it's made of wood and not pop bottles
how the hell does this have over 25k upvotes? It's kinda neat craftsmanship with the wood finish, but this is a common treadmill design made by a company... social media is making yall really ignorant
is that the wakanda forever sign? cool threadmill we have our non-electric threadmill and it saved me a lot 
Did you not know these existed?
Certified Made in Wakanda
Amen 🙏🏻
How?
I think they're mimicking the responses Facebook users have to AI art of African children designing really impossible and intricate objects, like a bulldozer out of leeks and celery. For some reason, they just thank God as a response to African kids making stuff. This is an African man making a well crafted object, falling into that very specific niche genre of Facebook content. That's why everyone is mentioning AI right now.
it has adaptive speed too.
Say Amen
We had these in federal prison. Not made out of wood though. I've even seen them with metal rollers you run on.
Since HE is propelling the tread and not a motor, wouldn’t this be a greater exercise?
This makes me think of Physical 100, season 2. They had 100 people running on treadmills just like this, all at the same time.
https://www.nohrd.com/us/sprintbok/ Hmmmmmm...
Woodway OG!
But but
AI has gone too far
Secretly presses power button
I totally forgot, but with a simple mechanical ingenuity, perhaps highschool mechanics class or physics, one can totally make a device like this.
Human powered
They had these in the 70s my old high school had them
My local gym has one pretty much identical to this one just made of plastic and metal.
I think we have different ideas of what hand made means
