again, if it's humanly possible, there will be a russian guy already doing it on youtube

Says that is impossible but he shows how its done with a picture of himself performing it. Busted

6:58 those are some flexible shoulders

Came for calisthenics but stayed for the engineering lesson 💯💯💯

I saw this suggested video and had to comment here too! The CTI was coined by Jasper Benincasa in the 1940's. He was the only one known to have performed it, and had a picture of it (more on that later). I met and spoke with Jasper's student, Jack Arnow, many times and Jack said that the CTI was not a matter of getting the body vertical. It was about lowering down from the bar and stopping when the arms were horizontal - that was the deciding characteristic. Jasper had also said the legs were held loose underneath, so that the body resembled a "7", as opposed to the 90/90 angles discussed. Jasper called it a "Close To Impossible" because it was so difficult to hold (his best was 3 seconds) - and this says a lot coming from a guy who could do multiple one arm chin-ups and one arm back levers! For the longest time, the only photo available of Jasper's CTI had the legs cut off, so there were doubts. It was an old picture from the 40's (it's amazing it survived as long as it did). Anyways, in 2012 after Jasper passed, his daughter was looking through his things and found ANOTHER picture of the CTI from the same instance as the original "leg-less" photo. Jasper's daughter sent a copy of the picture along to Jack Arnow, Jack sent a copy to me. This new photo clearly showed Jasper's entire body, as well as the hand written title "The CTI". Looking at the original photo and the new photo, it seems clear that some short period of time has passed (a few seconds), which would indicate a hold. This is incredibly impressive and in my opinion the holds we see going around now and days replicate Jasper's original hold quite well. For all these attempts, pressing out the arms straight doesn't seem like the preferred way Jasper got into the skill (instead lowering down with straight arms) And attempting to get vertical/90 degrees is not needed, and as you mentioned is physically impossible. Not trying to plug my website, but you can check out the CTI pictures and my analysis on the page titled "Jasper Benincasa: A Memorial". Pardon if the site is a bit wonky right now. Lastly, Jasper Benincasa day (March 25th - his birthday) is coming up soon! It's a day we all try feats of strength (usually a crank, one of his favorites!) Thanks and cheers!

To put the 700 Nm of torque into some perspective, a Lamborghini Aventador's 6.5 liters engine produces a peak torque of 690 Nm.

You: It's impossible Popey: Hold my can of spinach

“Because I like sports and don’t need that knowledge” 😂😂 heard so many people say that in school and well look at where most of them are

I don't know why this move even needs an explination. Just a second thought tells you, that the problem is in the weakness of grip and wrist extension. Two vertical bars for each arm might be a bit closer to possible

4:04 My man Osvaldo!!!

Enjoy to see you explain skills so everyone can see it's possible or not!👍 Thanks for that!🔥

Excellent video! The CTI is not physically impossible, but in practice with Earth's gravity it could only be done by someone with wrist extensor muscles in the forearm as strong as a car engine and hand skin so rough it won't rip. It would be cool to try this and other moves on a planet with much lower gravity (or send some street workout athletes on the Moon). This move was named by Jasper Benincasa, there's a picture of him holding it with an oblique body (so center mass is in line with the bar) and no false grip, he used something like sap to keep a strong grip on the bar. Also some of the CTI attempts in the end of the video are faked by using a thin rope that is not visible, Leon Pilous has a video about this trick.

I have to say that your explanations are very clear. I'm an engineer too and I'm very much aware of how hard it could be to clearly explain some physics concepts. Congrats 👏

Was just watching your old videos and boop, a new vid popped up

The comparative between artem morozov move and the way you hold the shovel was so accurate, must say

Finally someone said it! Well explained bro

I really love and enjoy watching your videos. Love it...

Great video!

PhysicsPal. This was really informative.

It would have been fun if you added the phrase: Or can you? at the end. Nullyifing the main statement made in the video. 😂

Calisphysics!!! Love it😘

Nice vid💯💯🔥🔥

Great video

great video awesome explanation :)

Great video

Dobry filmik i interesujący

I just wanna note how I find this an interesting science of a video (as many of your videos are). And it just irritates me how closed-minded people can be to find such things too “boring” to indulge in. I HATE closed-minded people like that, dude! But keep on bringin these videos 👌🏾

Did you switch over to wet shaving your head from the buzz cut? Looks good!

Big facts from Dave

Excellent

informative!! THX

Your ability to overcome challenges and keep moving forward is impressive. How do you find the inner strength to push through tough workouts? Hope to see you active in 2023

Anything close to infinity is just infinity, because nothing is close to it

i remember i was doing something similar with a hammer. holding it vertical from the bottom of the hammer was so much harder than holding near the metal. i wonder if someone is now going to use that T-bar as a method to increase forearm strength.

Awesome and insane

History of the CTI: the name was coined by Jaspar Benincasa. He was definitely the best bodyweight strength person of his era, if not of all time. Check out this great tribute to him from Jim at beastskills.com: www.beastskills.com/jasper-benincasa-a-memorial It also includes an analysis of the CTI, and an argument that Jaspar may have actually done it.

Pal: CTI is impossible Deuanuis: Hold my bar

Amazing advice, this completely makes sense. However, if you were to have the relevant flexion strength of the forearm to hold your body weight, would there be need for squeezing the bar to prevent rotation? ?

Dave is a smart dude.

Hey mattheo spinazzola basically did it

How about doing it on neutral-grip bars (placed vertically)?

Now I feel uncomfortable, because the video was so serious... I watched it with joy anyway.

Subscribed after 90 seconds. Nuff said.

Can you make a video regarding the reason or history behind the naming of bulgarian, russian, korean dip or autralian pullup?

For someone who often twist the throttle of my motorcycle I think I should be capable to do the cti

Holding that you can see that your legs would swing forwards out of your control, doesnt matter how strong you are

19:18 Artem morozov. This guy is all unique piece.

I missed your videos a lot, please upload regularly. Are you doing any job now or are you still doing freelance

Maybe it is easyer to handle on vertical neutral grip

Those CTI attempts look like someone tried to do a front lever but couldn't hold it so they dropped down.

very nice

Thanks for ur CTI explanation, well done!! Now what do you think of one arm human flag? Ik human flag has arm pushing and arm pulling, so can you explain them both and if its possible to do it with one arm. Btw just subscribed :)

Great video! My brother told me about his and I tried to do the math...I'm getting something like you need to be able to squeeze about 80-100x your bodyweight to do it?!

it is possible if you have a beast grip strength and a little overall upper body strength but it is impossible if the bar is rotating or slippery

This video was interesting, but I would have liked more real numbers. You show how the hand-bar joint is the key and provide a prop, why not do a simple experiment and remove all doubt? I like how you provided examples in your "One Arm Handstand Pushup" video.

Bodyweight static front raise

I didn't even know that this was a real exercise until this video. I thought I was the first one to ever think of it. I asked my friend who is a physics major if it would be possible and he said basically what you said. However, he also said if you did it with a vertical bar it would be possible. I wonder about the friction required to hold your entire body weight at arm's length, though, and I feel like it would be a similar problem. But he probably meant to have a T shape bar like this: _|_ and hold the vertical section with the crossbar preventing your hands from slipping. Do you think that would work? It might be an interesting video idea.

Damn I just the best lecture in torque so far by a calisthenics dude.! Suck it physics teacher!

What's up bro!

that's why it's called 'close to impossible' because if impossible is 0.0000%, then close to impossible is 0.0001% which is almost the same as impossible

Calisthenics + hidden auxiliary bar = nice magic trick.

It's not torque boi, it's moment

Which one is more impossible or possible - An inverted full planche or CTI?

What's your thought about a 6'7 tall calisthenics guy?

Actually, there's just one way to prevent rotational motion given an unbalanced torque: provide another torque that counteracts the torque already present. The two examples you gave were two different ways of doing this: either with a new external object providing some force providing that torque, or the friction between the axle and rotating object providing that torque. Nevertheless, good explanation of everything else!

0:01 me talk with my demon

What about vertical bars?

The one handstand push-ups is possible if your using momentum from a handspring.

Damn these physics lessons...

anyone know where i can find the background music?

3:17 That is not how this wrench works. You rotate in the wrong direction.

Okay! I'm going to try it But.. wait for me a bit to up to Super Saiyan God-Blue form first.

Which one do you think is more possible - CTI or Reverse full planche? I think they're both equally impossible 😂

Need to increase friction somehow

i have seen frank medrano do it a lot of times..have u chkd it?

Do CTI on P-bars

Since the victorian is doable, shouldn't thinks be doable? Or does it not count if your body is not completely perpendicular?

This move is actually allot easier then people think :') well if you don't train correctly or train too much each week then it might not be, anyways all you have to do is hold yourself at the top of a muscle up position, then just move your body a little bit away from the bar and hold it, over time you will be able to get the angle lower and lower until you hit this position, or you can hold the top of a pull up position and move backwards from the bar a little and hold, eventually you will get to holding the close to impossible move from this position as well :)

PhysicsPal ;)

Well if you theoriticaly had strong wrists and forearms enough to resist the torque would you do it? And if the friction was high enough that you wouldn't slip. Will it be possible then?

Name of it??

I'ma have an impossible Whopper for supper😉 Thanks for the video. I got huge Force btw😜

Well, I imagine that there should be data out there about the force neaded to actually rip the skin off from a human hand. That's the real limiting factor, because wrist strength could theoretically be increased enough to hold the position. Even then, the strength and durability of the body tissues can also be theoretically increased via progressive overload. If a normal person had to do a one arm-one finger pullup, her finger would probably actually be ripped off her hand, is not just a matter of muscular strength; and yet some climbers can perform that movement no problem. So maybe the durability of the skin could also be trained and increased to the point where this movement can be performed. I just don't see anybody genetically gifted enough putting the time an effort necessary to get such a specific skill.

*”It’s impossible until someone does it”*

Hi Wouldn't it be possible with two vertical bars? Because of the grip

Zeblackturbo can now do a close to impossible without someone holding his feet

Okay, but just to be completely precise. Technically it is possible, but practically the force you would need to overcome with your wrists is just unimaginable for humans.

I think that Jax from MK series, could do it easly ;)

If you were to do it on a square bar, you'd use your thumbs to counter the force. Now, in your head you might've thought this would be possible if it were done by a strong athlete (I sure did). However, if you run the numbers you'll quickly find out that, in that scenario, your thumbs need to handle 15x your BW. CTI is truly insane.

I love these philosophical videos! :D

The secret is just use more chalk.

If Ragnar Lodbrok says it's not possible, it's not possible.

What is the name of this movement?

If you reduce gravity its possible

dejan stipke does it with one arm xD

Torque or moments

Why im getting chest pain just by holding on the rings and doing dips?

1:07the clean'' impossible dip'' is actuali imposible because the shoulders should be behind the elbows

Rock climbers watching this video: *hold my chalk*

That's not even close enough
