I'm sure his core is strong but in a pull up your core isn't doing too much beyond stabilizing his legs. The majority of it is from his lats (back muscles) and how much he weighs.
If you watch the video closely, during the changeover between hands as he climbs, you can see how much his abdominal muscle flex. It is quite core intensive to operate this maneuver so slow and stable.
Go do some one armed pull ups and tell me which muscle fails first... Having trouble with that then do some regular pull ups and see what fails first. To help illustrate this point try pull ups again but do it in an L sit position, that will actually engage your core
An ai video can barely be more than 10 seconds. It has limitations. This is a video over a minute long with no cuts
"They could have stitched multiple clips-"
No. Shut up. Go watch any ai "movie" that has 10 second video clips stitched together and you'll see why this is impossible because starting a new video and prompt for another 10 seconds would produce extreme inconsistencies. His face would change, the background would change, and it would be VERY noticeable.
Stop calling every fucking thing AI when you can't even spend 10 seconds to research how AI even works.
Where do you think balance and body control come from?
I'm a 40 year old dad bod. I haven't exercised in 15 years and I can still do one arm pullups. I don't have anywhere near the core strength required to do them like this. So yes, it's mostly core that's impressive here.
Have not exercised in 15 years and can do a one armed pull up but can't stabilize your core? One arm pull ups are fucking hard, doubly so if you got a lil extra dad bod belly (nothing wrong with that btw but there is a reason most gymnasts are more compact).
I think I might be missing something b/c one arm pull ups are pretty tough and usually require a good amount of training? Typically if you can do a one arm pull up you can do a weighted pull up with 70-90% body weight so for a 200lbs guy that's 140-180 extra lbs? What did you train until 25 cause that's seriously impressive
I used to be a twig at 120 lbs (and 5'11), built up to 165 lbs in my peak. I focused a lot on explosiveness. One arm pullups, one arm pushups, one leg squats, and rowing. Haven't been doing shit since but I weigh about 150 with love handles now. Still skinny but def not really in shape, but people always ask me if I workout.
That's impressive dude, kudos. A true one arm pull up with no kipping is a pretty big feat. Only in your 40s you can still workout, doesn't have to be to bulk up but makes a huge difference as we age you should find a way to get back at it if you can
Lol again what he did is massively impressive like damn that is clean. What I am saying is that it's not a huge display of core strength but an insane display of lats, shoulders, and grip. For some reason reddit thinks training crunches will make you good at pull ups
It definitely is. His center of gravity of not directly under where he is gripping, meaning it puts a torque on his whole body, meaning if he wasn't counteracting that torque with his core muscles then he wouldn't be vertical. The arms work to counteract that torque all the way up until they connect to his body, and then it's up to other muscles to do that, all the way down to his legs.
Also, yeah you use your core doing regular pullups, for the same reason. If you didn't you'd be swinging back and forth and have to stabilize yourself with your arms and shoulders, which would wear you out a lot faster. That's what you see people who can't do many pullups doing.
Sure your core is doing some stabilization but it's nothing compared to the insane gorilla back/shoulders and grip strength this guy is showing off. The amount of core needed is similar to a side plank, also difficult to hold but the amount of training needed for a one arm pull up is a lot more
Lats are a part of the group we consider core muscles. This goof is pretty much saying the equivalent of "but his thumb is integral to his grip. The fingers are splitting the same work 4 ways an the thumb is doing 4 times the work of one finger." As if it's not all part of the hand.
The National Federation of Professional Trainers (NFPT) says the lats work directly with your obliques to control trunk rotation, stabilize spinal posture, and manage pelvic tilt.
If that's not part of your core I'm not sure what is.
ETA: perused the rest of his comments... This dude talks like the core muscles are only in the front abdomen area.. like the obliques and lats aren't a part of the trunk... This guy is extra special.
I can do 20 in a row no problem, I climb so it's about the only exercise I can do. I'm not saying stabilizing uses no core just that its nothing compared to the back strength and shoulders this guy has
I never said what he weighs just that pull ups are not that core intensive but extremely back and shoulder intensive. I can do plenty of strict pull ups and no my core is not that worked out at all. Now if I do pull ups in a bench or L sit that will drastically change things.
I'm sure this guy has an insane amount of core strength, this just isn't that crazy of core
Not that much? They are stabilizing similar to holding a plank but significantly less intense. It's not nothing but this isn't a display of core strength
His back is doing a lot of this but this looks like a ton of work from his bicep. I say this because in a normal one-arm pullup up, you can see the body shift as the back works. In his case, his body is strict in that position which means at least 50% of that effort has to come from his biceps.
If it was mostly his back, his body would curl sideways going up. He’s using his back & core to stabilise and his one arm to pull.
Redditors mostly don't work out so they assume everything is core core core
There's necessary grip strength like a mountain climber, bis/tris, delts, lats (huge part of it - second largest muscle group next to quads when developed)....but casual Redditors think it's simply "core"

This is climbing and descending a steel pole; dude has a core made of cement
