Reverse causation for sure. No grip strength does not increase longevity, but if you're old and still have a muscle mass to have good grip strength, that's probably a good sign that you are healthy and have a good chance of living longer.
The only sensible comment.
Definitely, also disorders like muscular degenerative conditions as well as hormone disregulation that leads to muscular atrophy are associated with higher mortality. It's not that old people with more grip strength are better off than older people of normal grip strength, it's that older people with conditions that lead to weaker grip strength that are already associated with lower lifespan.
plus the fact that its not only diseases but lack of active lifestyle as well. Physically active 80 year old has higher life expectancy, than inactive but quite healthy 80 yr.
Yes, the title immediately irritated me 😡
i love building and maintaining strength of grip and hands , it helps a lot. 🙏💪✊
I'm still amazed at the fact a channel like this even exists. The production and educational value is off the charts, really.
Nothing would be done for free they getting paid thru TH-cam
I agree. 👍🏽
@@JamesCruz-fg1bmnobody mentioned it being done for free. The guy in the video also has to pay his bills. What are your expectations?
Btw, you can watch his videos for free.

I'm 61 and a big dude. I've recently concluded that the food industry is putting lids on jars WAY harder than they used to. Someone should look into this.
The dryer is shrinking our clothing more as well
I'm 55 and realised that cheater glasses lose their magnification over time.
@ronjones6977, Nope. You're obviously just getting weaker, probably signs of cognitive decline & Alzheimer's 😁🙋🙏
Ron is claiming he's "big", meaning he's actually fat 😁
Even the AARP doesn't address this!!!! The humanity.....😂
Props to the person who gave their body for our education and props to teacher who gave his knowledge.
Thanks man! I donated that arm 💪 right after crocodile 🐊 ripped it off during Africa safari last year. 😳
And they got to keep their cute lil fingertips!
For real, though. Very honorable thing that deserves recognition. I know all the lab guys are taught to give props but we should too.
@@alphaomega1351Ahhh, that kind hungry crocodile that supports medical education 😊😊😊 so glad it gave back the delicious arm for us.
Props to the unique personality that can skin a cadaver. 😅

Righttt😭
Right? It makes the cadaver... human.
Almost made me lose my breakfast.🤢

SAME!!! I froze for a second like wtf did i just see😳
Finally a sane video on the topic! It's a correlation and not a causation. Great example is my father. The man had really strong hands and grip due to the physical nature of his work but died at 50 because he was an alcoholic who smoked almost a pack a day and didn't give a zero f..ks about his own health.
@alanbaskaev3907 being an alcoholic and smoking tobacco is a great way to destroy your testosterone levels and torture your chromosomes :(
Grip is an indicator, like backwards walking balance, and gut health. Doesn't have to directly relate to longevity even if it's a hugely visible indicator, and helps with surviving
gut health is pretty direct, cut and clear especially if you know the species of bacteria living there - not as cut and dry as amount of muscle
Holy shit that dissection is immaculate. Incredible work
PT here, just gonna share this here on the off chance it helps even one soul: this is the BEST exercise(s) I have found to help maintain and improve my (nerve damage) and patient's grip strength.
Get either a 2# (much more practical) or 5# (better resistance- perfect for athletes) bucket and fill it 3/4 full w/ cheap rice (yes, I know it sounds like a hassle). Then do these 3 exercises in 1-2 minute increments:
1) hands in fists, flex your wrists forward/backward trying to dig to the bottom
2) using fingers ONLY, wiggle them forward/back again trying to dig to bottom
3) hands in grabbing a door knob position and rotate wrists left/right (pronation/supination) just like turning the knob, digging to the bottom
Avoid cheating by using upper arm/shoulders or leaning to much upper body weight leaning into the bucket. It's hands/wrists only.
You're wrists and hands will get that wonderful muscle burn in no time and you'll notice improvements quickly. Keep the bucket in an unused space and do it 3x/week. I know a bucket full of rice is impractical but it's more effective and cheaper than weights/grips, and targets ALL the intrinsic muscles, not just 1 or 2 major ones. Good luck!
Great explanation!
Do you see this helping a pianist who also works in building and piano repair and humanitarian work (=loading+unloading trucks)?
I'm leaning towards trying this...
Do you have or can you refer to a video example of your suggested exercises?
It was easier for me to get sand from the nearby beach than rice. I never tried with rice, but sand definitely offers a tough resistance. It feels almost impossible to fully dig the hands into it and rotate inside. Do you guys think rice is technically more effective for these exercises? It would cost me around 60 bucks to fill up a 40Kg bucket with the cheapest rice I can find.
You only need a 20L bucket, you can also use buck wheat. Sand is too dense.
Sound ms like OT exercise. I’ve had knuckles replaced and 3 months OT doing similar
Dead hangs are incredible for health. I can do up to one minute and thirty seconds now, and I remember when I first started, I felt the most satisfying pop and subsequent relaxation of my spine. It was a really good feeling, as if my spine was finally able to be in a proper, fully stretched position. I also do farmer's carries, which if done properly, force you to walk in the correct posture. As someone who spends a lot of time on a computer and loves it (natural programmer here), I knew it was not good for my body to sit all day. Adding a few hours of workouts in the morning with a lot of exercises that tested my grip and worked my traps has done wonders for my standing posture and overall strength!
Finally got rid of my golfers elbow thanks to dead hangs, one handed did wonders.
Good stuff 👏
A great combination of exercises!
Institute of Human Anatomy: "Does Grip Strength Really Help You Live Longer?"
Answer: "Yes, definitely, if your gripping on for dear life"
😂
I think Syl Stallone has something to say about this.
Brilliant 😂😅
It's it's it's ummm grippy
I recently had an accident that fractured two of my phalanges, affecting my grip strength. Thanks to your video, I learned a lot about improving grip strength and found it incredibly helpful in my recovery. Thank you for sharing such valuable information!
Glad you liked it! Thanks for watching!
dont worry bones can heal completely that too in a short time span. One ought to worry only if they have a tendon or ligament injury.
@@theanatomylabI broke my hand punching a dude in the head, numerous times, bare fisted. Ask any professional boxer if your hand recovers 100% after a break or fracture, it doesn't. This is the real reason boxers wear gloves.
2:00 that guy scaling the wall... His hook came out of the cliff as he fell.
He's the cadaver!
Proof that grip strength DOES have a causal relationship to longevity!
Dude should have squeezed more tennis balls.
I was losing my grip strength in year 2023 which was happening due to cervical discal herniation and compression of nerves. It was such a wierd and worst experience while losing a whole left side of your body...
Now I had surgery in last year sept and it's all good now!
Grip strength does matter!
thanks for sharing
Glad you are doing better!
Going through it right now, what surgery did you go through?
I’m in a similar situation from a deadlift not going well, lost control and form was broken so now just doing body weight training to stay in shape
@@kevinparker7247 :)
I was out of work with an injury for the last year and I just went back two weeks ago. I work for Pepsi and the job is very physical and we are grabbing things all day long. My hands have been so sore these last two weeks getting back in to the everyday routine of handling so many packages of soda. This was perfect timing on this video as I sit down and eat my breakfast this morning. Thanks for all of your amazing work.
Thank you for watching and glad you have been able to get back to work from your injury!
I can empathize. I do a lot of hauling and loading including 25kg items and leftover pellets in humanitarian work. All while officially being a classical pianist as well.
For me, well fitting (not too tight) thick rubber gloves as one might find in a workman's section of a hardware / Home Depot type store or a garden tools area or masonry/brickwork section are immensely useful. They tend to spare smaller muscles a bit in favor of engaging larger ones due to the huge increase in surface grip. They also protect somewhat with bumps and hits. I have occasionally used orthopedic hard-lined "braces" for like an hour and a half while lying down or not using my hands after work just to calm things down. Those were 65 Euros each out of my pocket but very worth it particularly when certain hand areas clearly struggled with the workload. On occasion I used less rigid braces or "rubber support gloves/mittens" that an orthopedic surgeon didn't see much benefit in but it seemed to help. Same with sports tape, but all that is best discussed with a good physical therapist or orthopedist first. And never "tight."
On heavier days I sometimes submerge my hands as far as I can in a sink of water as hot as I can handle as long as time permits on a break. This seems to alleviate things, improves blood flow, relaxes muscles, perhaps supports the body's natural process of removing toxins from heavy-use areas.
I would love a video similar to this for the lower leg!
We will add it to the list!
I’ve always had a hard time understanding and memorising the muscles of the forearm, their attachments and functions, but this video helped me not only to understand them, but to also appreciate just how complex and fine our hand muscles have evolved just to do these everyday tasks and be versatile with finely handling pencils to just gripping and lifting up the whole body from the ground!
Great Video. There are numerous academically accredited influencers here on YT who advocate grip strength training to promote longevity as if the causality goes both ways. This goes to show that even if someone is a "Professor" the minute he becomes an influencer who supposedly knows anything about everything and spend too much of his time "making content" or interviews instead of research or academical work - you should take their content with a pinch of salt. Not all MD Doctors or Phds are the same on social media.
Every time I watch a video like this it makes me so happy that I’ve donated my body to science. To know that after my death, new medical students will learn from it, is awesome!
I have Rheumatoid Arthritis and your awesome video helped me better visualize how my tendons work and where the pain is coming from so I can manage it. Thanks
Guys, your channel really is amazing. Seeing the way the human body works is absolutely magical!! it is insane to think that some seemingly minute aspect can have such a complicated process of creation, and i think that process is just as fascinating as the result. Thank you so much for putting stunning info like this in such a comprehensive and engaging wayy :) You truly do justice to this fascinating mechanism.
True, everything has a beautiful design that we would have never been able to come up with using our limited understanding
Thank you! We very much appreciate your comment!
@Josef-EU so you really believe that a random fish was able to breathe on Sand and was also able to feed itself while on the sand so that it had enough energy to potentially reproduce with itself so that someday it could become a monkey that would become a human that never grew a forehead but somehow has a forehead? All of those genetic traces are gone so where did they go if we are supposed to be progressing and evolving forward? Trust me the body couldn't survive without all of its pre-designed features, if we were to follow Evolution everything would have died before it had the chance or the ability to reproduce. Natural selection is just how the bloodline moves forward what are the strongest typically survive although nowadays everybody's pretty weak
I find the hand so fascinating! I was looking at some anatomy textbooks, trying to find out why you can bend the PIP joint without bending the DIP joint, but not the other way around. Seeing the way one tendon splits the other was really interesting and I even got to see it in body worlds some time ago! Anatomy is just so amazing!
Thank you for all the work you do on this channel!
I've studied the tendons and muscles of the hand multiple times before without fully remembering everything, but your anatomy lab illustrated explanation finally helped me learn it for good. You're a fantastic anatomy instructor. Thank you!
Last August during a hemicolectomy I picked up a blood clot in my left subclavian vein. It left me with some nerve damage in my left arm, limited flexibility in my wrist and no grip strength. Earlier this year my grip strength had crept up to 4kg, it is currently at 18kg and am able to use the brakes on my ebike! Still extreme carpal tunnel like symptoms but the neurologist has said it will take time, another year to 18 months. There is very slow progress, but following the exercises given to me by physiotherapy and occupational therapy there is very slow progress. It is eye opening as to where grip strength plays an important role when you don’t have it!
I dunno that it makes me live any longer, but every night since I was 12, it reminds me why life is still worth living...
Lol!
Dude....😂😂😂 No truer spoken words from the male species.
Buhahahahaha!!!
You know that you can move on to better things now, don't you?

Data shows that elderly people use to die few years after they start falling or after a hip break. Grip strength can prevent falls and that’s the main reason why it is related to longevity.
Also, good feet health and strength can prevent falls and that’s exactly what respectful shoes help on (in contrast with shoes that prevent your feet from feeling the floor).
As an artist who draws a lot of figures, and so forth , for sketching, drawings, and painting, I've done a ton of anatomy drawings over the many years, and thus I found this very interesting. And doubly so in my case, as I'm quite holistically oriented in my life-style (diet, exercise, etc.) for decades.. So, your video hit both these areas of interest for me- anatomical knowledge along with valuable health information. Excellent!
Brilliant video! Facilitating to see the linkage between exercise, strength, and wellness. As I get older, I am more aware of making myself falls resilient; this vid drives home the point. The anatomy lesson was very interesting. I hadn’t stopped to think about the muscles and tendons in the forearm. Great work!
Love this video, I'd like one like this on the back muscles and one on leg muscles. thank you for all your knowledge and video content ✨🤓
Something related I've always found interesting is the difference in how far each finger can move independently DIFFERENTLY between both hands (i.e. my left hand i can lower my pinky without moving my other fingers, but my right hand can't (it has to take the ring finger along).
I'm sure the main correlation between grip strength and longevity is that people with greater grip strength tend to be people that are more active
Congrats for watching the video
It's more about maintaining lean mass than being active. Being able to be active correlates with the first one, but the root cause is above sufficient protein intake.
@@bennyklabarpan7002 I resemble that
Thanks for a great video! Much appreciated
I really enjoy your videos bro. Keep doing your thing💪🏾
Incredibly informative. Thanks!
Thank you!!! Informative and educational!😊
I work grip twice a week so this is really cool to see what's going on inside my antebrachium.

@@theanatomylab I was a mailman for 33 years and had incredible grip strength in my left hand. Five years after retirement, I've noticed my grip strength has weakened a lot. Jar lids aren't my biggest problem, but those pesky anti-tamper seals on bottles and jars are the worst. Getting old blows dead bear.
Highly educative & professional. Was not ready for those fingers tips visuals
That was very helpful. So logical. I wish I had an instructor like you when I was in school.
Dear Jonathan, Love your videos. Thank you for all the knowledge you bring. I get to learn about our bodies without having to being a med student. Keep up the great work :)

Impressive fitness knowledge on top of explaining anatomy. Respect!
Very much enjoy your lessons
Want to watch more and more often as you are great instructor
Great video! I wish you also commented on the thumb positioning when gripping something. For instance, doing pullups/deadhangs with/without thumbs wrapped around the bar feels significantly different (without wrapping easier for me). I always wondered why tough.
finally some content for which i subscribed cadavers
This video came just in time because on June 1st the day before this video was posted, I just purchased an adjustable grip strength trainer for $15 in a garage sale near my house. Then on June 2nd this video was posted. And finally on June 3rd this video was recommended to me, and I posted this comment. What a convenience coincidence.
Edit: Just a cherry on top, I am using the grip strength trainer tool as I am watching this video!
Thanks, I always found a need to talk about the other than the knuckle joint but didn't have any name. Now I can just say interphalangeal joint and everyone will know what I'm trying to talk about. And obviously proximal and distal to make it more clear.
Thumbnail caught me off guard 😂.
😂
The fingernails too. It's funny how seeing the skin and nails makes you remember that this was a person once. I started imagining the person based on those finger tips. Wondering if they were male or female, fit it obese, young, middle aged or old.
Yeah seeing those nails and skin bring you right back to the fact this was a person.
They say the nails still grow when you die.

Hey, This was a very informative video, loved it.
Could you also make a video on (TFCC) Triangular FibroCartilage Complex and all wrist bones if possible please?
Very hands on, on this episode. 👏
one of my most favorite channels on yt!
Great video!! I wondered if the resistance training I do 3 times a week qualified as improving grip strength. I’m 62 and still not great at hanging, working on that. I can deadlift 105 lbs for 10 reps using a mixed grip. I don’t use wrists straps for any of my training which I’m hoping adds to the increased strength. Thank you for your awesome and informative vids 🤓
Excellent video... as usual! : )
Hello!! I love your videos!! I wish they were Spanish dubbed versions. So much of the Hispanic community goes of off superstitious beliefs. Don't get me wrong we be having some miracle medicine down south, but the details of this video are so detailed I know this would teach them some amazing human anatomy.
I volunteer to be hired! Lol I have a nice voice is what I've been told often by others lol
As someone who trained BJJ in my 40s I can say it feels surprisingly good to develop grip strenght. I think most of us undervalue how many times we CAN split in other muscle groups if we have a firm grip and use our arms too.
Great information
Jonathan is truly the most AMAZING anatomy instructor! I was blessed to him teach my anatomy class at the Utah College of Massage Therapy in 2012!
Unfortunately my class didn’t get the opportunity to attend the cadaver lab at the U😢
I’ve noticed that tendinitis (inflammation of the tendons) will negatively affect your grip strength and end up leaving you in excruciating pain.
This is caused my repetitive motions, over use, and it leads to a build up of scar tissue.
So give it rest, release the tension in the muscles and other tissues around the area. And get the inflammation under control. Inflammation is like a virus and can spread throughout other section of the body. So treat your body like the machine it is, keep up the maintenance, just like you would do with your car!
Sleep well
Eat well
And live well!
This was extremely interesting given a horrifying crushing of the wrist not so long ago.. cheers
thank you comments for the cliffs notes
Would love a full wrist breakdown!
very interesting! i have a condition know as hEDS. basically an invisible disability. it causes my connective tissue to be very loose over my whole body. unfortunately it led to my joint dislocating and has impacted my life highly including my grip strength. i'm curious how someone like me with their muscles and connective tissues issues, how my tendons and stuff would look? its so amazing how complex the human body is.
Fascinating, as always
I don’t know why I watch these. I’m a software developer and I don’t really do anything related to A&P but the body has always fascinated me since I did a couple of years of training to become a fitness instructor decades ago.
It’s amazing that we have this on TH-cam to help us learn things that interest us, even if it’s just for the sake of learning more.
Those finger tips gave me a chill
I do work grip strength with rope climbing (only arms, no legs), rope pull ups and so on. This really works flexors, and some people may get golfers elbow because of that . If they don't also work their extensors to keep both within some balance.
I was hoping extensors would be covered too as just about no one thinks about it till they get golfers elbow and go to a physical therapist that will have them work on extensors. You can already be doing this and not go through dealing with golfers elbow.
Rock climbers: can you talk about pulley injuries???
I was trained a professional level classical pianist, and I still continue to practice and occasionally perform. I see a fair amount of overlap here. I work a lot in humanitarian projects where the subject of "grip" got my attention due to the amount of grip I need on heavy objects and boxes for which I prefer to wear thick rubber gloves for ... "grip"!
I also fix up old pianos from time to time and pulling replacement strings while tightening the tuning pins also requires quiet a big of grip. The extent to which playing/performing, hauling stuff and that repairwork taxes the hand in certain ways and even the whole arm all the way to the back of the body has surprised me sometimes.
Not exactly the same type of grip as that of a rock climber, but I totally love this level of knowledge and the dissection arm example. Is that something one can buy somewhere and if so, where could I find that please?
It could potentially be very interesting for me as a pianist and piano teacher. An entire upper torso would be great to have access to. Let me know please if/where I might be able to get "my hands on" such items, so I may gain a still better "grip" on things.
Much obliged,
wk
Postscript: I did not mean human cadavers but an artificial, "working" imitation 😬🫣🤔😁
2 years ago, I tore (traction tear) the common flexor tendon (30%) in my left arm, it took 1 1/2 years to regain my grip strength, but the last measurement was 49 lbs. and though I lost about 5 lbs. of grip strength from the injury, and my hand still goes numb while i sleep, I feel I healed really well. In Nov of 2022 a a coworker manipulated equipment and a piece of that equipment hit me on the inside of the right elbow/ forearm., in February of 2023 I tripped at work and fell on the outside of the right elbow. X-rays show an old chip but otherwise all doctors (3 Ortho's) all say my arm is fine, yet it isn't, i started with 60 lbs. of grip strength and my last measurement was 35lbs. The pain isn't where I fell but where the equipment hit me. Work comp says they aren't responsible even though both injuries happened at work, and both were reported. The pain is the worst when I wake up, probably a 2-3. but the hand falls asleep, but the most important thing is that loss of grip strength.....do you have any ideas how i can build it back up my over strength has declined also in that arm. It's really annoying at this point because I used to kayak, hit the heavy bag and shot archery. The physical therapist said I can do none of those until I'm healed. Obviously, I didn't continue with PT because work comp won't cover it, any advice/ exercises you can suggest would be appreciated.
The largest parts of both sensory and motor cortex of the brain are dedicated to hand and fingers. So training grip regularly would also keep a large portion of the cerebral cortex healthier.
Great breakdown! Thanks, I feel smarter now….🙏🏽

Great video!
Fat grips are also a good way to passively increase grip strength when resistance training, like adding fat grips to dumbbells during the farmers carry exercise.
Wrist rollers don't increase grip strength as much as forearm strength but it doesn't hurt and they're easy to make.
I have an adjustable grip strength trainer that goes from 55lbs to 198lbs, I keep it in my work bag and use it almost daily but I am not a rock climber.
That said I hit a plateau with my deadlifting in that I can't go too much heavier or do more reps because my grip strength is lagging behind.
I also do Parkour and Striking Martial Arts, and am starting grappling soon, so great grip is needed for those as well.
A note about manual labor. As a mechanic, we use our hands a lot and while your grip strength can be strong, there's a great risk of developing arthritis, especially in the thumb joint which can cripple grip strength as you become unable to use you hands over time. Manual labor is deadly for joints over long-term.
Many thanks to the donor who allowed this video to be possible. I was hoping to hear more about tennis elbow and its connection to grip.
good one, I have wood blocks like that in my garage.
Question: So, I learned from this video that the FDS is responsible for bending the PIP joints of the pointer to pinky fingers, and the FDP bends the DIP joints of them as well. Why does it seem common to be able to isolate the bending of the PIP joints of each finger, but then the DIP bend seems to commonly cause both the ring and pinky DIP joints to bend together as a unit? Is there an anatomical reason for this?
Thank you for all you do, I truly appreciate you sharing your knowledge and educating us on the human body. It's so interesting and humbling.
If I remember correctly, and that was a long time ago, I seem to recall that flexor digitorum superficialis has two tendons in the forearm in some people but only one tendon in others. The latter is considered evolutionary more recent.
QUESTION:
Were the fingertips
part of that cadaver, OR, is artificial?
