Question - so, if I “turn on a DNA switch” by creating a hypertrophic environment, does that mean I can pass “better DNA” if I father a child? To rephrase, are you saying, or, can we deduce, that we can pass acquired traits to offspring, and not just purely genetic traits? If that is true, wouldn’t that mean people should lift or do anything possible to turn on these switches prior to procreation?

I apologize for commenting about this but i really need to know i just saw you're video how exercise affects the heart made a year ago and I was wondering what would happen if I exercised with a leaking heart valve its mild I don't have to take medications or anything but I wanted to get you're opinion on the matter.

[@alvarorubio1993]

As a construction worker that has to move a lot, carry heavy things and use power tools I can say that my job is essier after I started working out. The fatigue from weight training does carry over to work but the same is true for the gains, if anything now work feels more like the strech and aerobic part of working out.

[@justmyself1000]

I thought about why don't construction workers look jacked. Then one day at work...I realized that I was not necessarily using my muscles..but using my joints to create mechanical advantage. This is why my joints would ache. I also used my joints to stabilize my body like say when having to put my body at a strange angle to tighten something. I started to really pay attention to this and the position on my body and trying to use more muscle instead of muscle pushing joints and it made a difference on fatigue and how my joints felt at the end of the day. Didn't do much for hypertrophy, but did help with adaptation.

10:50 was spot on…usually at an early age the driver behind strength training is aesthetics but when we get older the motive is primarily for health reasons; aesthetics are just incidental.

[@gatoryak7332]

When I was a young man, I used strength training to support and enhance my fun activities which were athletic endeavors. Now, I'm an 66 years old. I still do strength training and I still do fun athletic activities at least 3 times per week. A side effect is having a physique that people admire without looking like a 'jacked' body builder. Most people my age are fat, decrepit, and depend on more than one prescription drug. I think that I made the right choice. Yes. I'm just one anecdotal datum point, but I hope that my example will help somebody coming up behind me.

I’ve been weight training since I was 12 years old. I’m 62 now. I recently had open heart surgery to replace a bicuspid aortic valve that had a 5mm hole in it. I just went back to weight training again and “Muscle Memory” is a real phenomenon. My muscles responded right away. Although I’ll never have the 19” arms that I once had at age 18 (non-steroid), I do feel so much stronger and fit. Two tests that individuals can perform at older ages to gauge their fitness are: 1). How long can you hang from a chin-up bar. 2). Can you get up from a prone position on the floor without any assistance from any object - just using your own body to get upright. If you can’t do either, you would definitely benefit from resistance training.

Indeed! I used to be the same - sporting 18" (naturally gained) arms, super strong, etcetera. I am naturally athletic, but I was genetically skinny, started weight lifting at 150lbs!🤣I desired bigger muscles. My older brother showed me some tricks for mass and strength building, and I was 210lbs in a short time, like 1.5 years or so. Incredible! BUT, guess what! I'm 44 now, and my body isn't what it used to be. I drank heavily for some years and alcohol took its toll. I don't look horrible, but my circulation has been impacted and my joints are weaker. Alcohol is bad stuff, antithetical to weight training. It actually stops the protein synthesis! Lesson learned. 😎

[@professionalcommenter]

So I recently started really working on weight loss and building strength in my muscles. I have Ehlers Danlos Syndrome and it causes faulty collagen production. Which in turn causes joint subluxation and dislocation, which then can and does cause tissue damage, muscle damage, scar tissue and chronic pain. Since I started doing resistance training in August of 2022, my pain has decreased a lot and I feel better as I've been trying to work on areas of my body that normally wouldn't need the same training, such as my feet, my hands, ankles and so forth. As someone who already needs a knee replacement at 38, this information will stay with me and help me prevent further injury to my body. Thank you! 😊

Rebuilding muscle after serious atrophy is definitely no walk in the park but good to understand that the base is still there. I'm still in physical therapy after extensive lateral ankle repairs in October of last year.

[@extrastuff9463]

Very different scenario for me but I lost a lot of muscle mass in my left leg, hip that slowly got worse limiting its range of motion. Probably waited too long with it, but it's much easier to tell someone to go to the doctor than go yourself. After an xray I got a referral to the rheumatologist and orthopedic surgeon, it was clear I needed a total hip replacement (and have some extra things to worry about long term from the ankylosing spondylitis). But basically there were a few muscles on my upper left leg that with slight pressure on it I could feel the bones beneath, it was also very skinny compared to the right leg. Only a few months later I could notice it gain a bit more volume and I couldn't feel the bones easily with slight pressure anymore. Now a bit over a year after the surgery left and right appear very similar and in strength too. Only raising the left knee while standing on that resistance training device still has a serious difference (19.5kg vs 42 kg). I also noticed that the initial recovery of basic strength was very rapid but after 3 months starting normal exercises progress got a lot slower. Still it was surprising to me how quickly it all recovered, not being in pain/discomfort while moving certainly helped me to stay motivated. Also interesting how a steady normal walking pace just after I started being able to do that again would quickly make me sweat and raise the heart rate up to 150 or so, but my anemia was worse at the time too. Now it doesn't get anywhere near that high with just normal walking on flat terrain and I can easily walk 8 km again without any meaningful rest (and probably longer, but I get bored and tend to head home).

Thank You Justin for this video! It pairs very well with Jonathan’s video last week. I’m 56 and started strength training a month ago and I am still learning that I need to increase the weight so that I can exhaust the muscles by the end of 3 sets of #X! (I had been increasing reps when I should have been increasing weights. I’ll keep at it for a few months to see if I discover personal benefits that give me a stronger motivation/desire to keep at it. So far I am just tired, so getting better sleep!😂🏋🏽😴

[@ggfdd5925]

just fyi, you don't have to train in sets of 3 at x repitions. it's just an easy and practical way of doing it and there isnothing wrong with it, but there are many, many other ways of doing it. x sets at x reps, one set every 2 hours every day, most concepts can work for certain goals. increasing reps is also good. optimally you'll train both endurance and strength. low rep counts (rule of thumb, you're absolutely done after 2-6 reps) train strength more effectively, while higher rep counts (up to 30 can be effectively utilized in "classical" rep based resistance training) prioritize endurance. however, both methods don't isolate strength or endurance completely. you'll get some of both either way. if you just want an allround concept that needs little thinking the good old 3 sets 8-12 reps you're probably doing are a good midrange. don't go all out every time, you can leave 1/2 reps in the tank, neither go too hard to ensure good recovery nor too soft for sufficient stimulus. focus on great form and control if your ego allows it. it can be really humbling going from 12 shitty pull ups to 4 exceptionally clean and fast ones but it helps you not injure yourself as easily and it definetly looks better

What do you mean looking good and being strong is the "side effect"? That was my main reason to start lifting.

While that may have been your primary intention, from a health standpoint, looking good and being strong are tertiary benefits to actual longevity.

Yep. Because if you happen to get into the steroids craze, you'll get strong, and look massive (whether that's looking *good* is debatable) but you are likely to die young as has happened to a bunch of pro bodybuilders. Without longevity, there's no real gain in being strong and looking ""good.""

cool, just another pebble of sense in the landscape of knowledge, definitely makes sense: the key stimulus for growing muscle is the stretch under load. Even 4h of passive stretching per day stimulates growth of gastrocnemius. I can image that this increases the distance between the nuclei. And the longer the total duration of that the more intense the nuclei can sense that they got lonely. Question: how does come that tendons grow? ok they are growing slower, but why do they grow at all, if used and stretched? . so, finally about you, yes you: I got kind of shocked when you said you are 35. Your skin looks much older... You should care about vit c and zinc, the amount of which are effectively arriving in your tissues... 1g vit C and 50 mg of Zn, together with a lot of green tea, a lot of hot baths, and mct oil treatments will help

A common misconception is that strength training is a grind or something you endure, but really it's a balancing act, and if done properly, you should feel good, well, balanced and stronger. Sadly, most people lose their stability and become weaker because they didn't know what they were doing when they were chasing power through the grind.

[@alphamale3141]

I agree with you. It’s not a grind. When recovering from a set of nine reps, (one rep from failure) it’s a time to think/plan/meditate. I’m pushing 76. I’ve been doing this for over 60 years. I still practice law and manage my own assets. Resistance training dramatically slows down the aging process - both physically and mentally.

Podiatrist recommended better shoe choice suggesting good running or hillwalking shoes and insoles with sorbothane for faster relief, was also told to do with stretching exercises and directed to the nhs youtube video for plantar faciitis exercises.

Thanks! This video answered a lot of questions, including one I had regarding muscle atrophy after watching Jonathan's video. Bottom line: do resistance training. 💪

[@markfinlay422]

Love this topic! Epigenetics are an awesome topic that we are only getting to know about.

I have always hated science but somehow I really enjoy this KZbin channel.

Scientists: weight lift, it's good for you. Pop Scientists: lifting kills you, stop it and be fat!

I wish you addressed the supra physical Testosteron (or anaglgues) doses that people are now used to put in their bodies

I'm the guy on the left in the photo. I will turn 50 soon. I stopped this weak space immediately when you said you were 35. I looked like a Greek God at 35, and I never used a single PED. PS, Shattered Spine, Implants, bone grafts, fusions, over 170 days in the hospital, a total hip replacement, a completely reconstructed right hand, disease that feeds on my bone marrow, a pain pump the size of the Large Stanley Tape Measure implanted in my back, I've been put to sleep 43 times in 6 years. I had AT ONCE!!! aka simultaneously 4 PICC Lines, and 7 IV lines, peed in in catheter, #2 in a pan, washed with a hose pipe in an ego crushing basket lift.... I now walk, run, and lift weights. I have 28 Titanium Bolts in my Spine Alone. .... Imma back out REAL QUICK before I get angry over your weak pity party, and search for more videos that allow me to see what my body actually looks like on the inside. This video does NOT belong on this channel. You made me feel creepy and I literally shivered from the cringe. Literally!!! Physically cringed.

I’m super keen on learning about your extra long colon as I have it as well.. what are you doing about it? Please send me any answers you are implementing… thank you

possible to influence such muscle changes without workouts?

I've wondered this for a long time. I've always been sporivly actief up to 24 years . Is been sedintary for the last 4 I've gained like 2 kg it's surprisingly stable. My diet has been the same , apart from the first 2 months I'm pretty sure I can restart it. Not that I necessarily want to my job doesn't require it but I wonder how much is Retained . My muscles mass has declined but how much trench work would make it eayer to restart.

11:38 does that include a cadaver ?

[@OK-Computer]

Great video. HOWEVER what ruins the credibility of the channel is supporting a overhyped and overpriced MLM-style supplement with overblown claims regarding its efficacy. Just drop it, choose a better sponsor and please put it at the end of the video.

[@daniellebailly720]

I love your videos!! Thank you so much! Keep em coming pls 😊 Any information on the auditory system and things like hyperacusis ?

This is one of those channels i consider KZbin GOLDMINE ! Thanks for all the efforts you put in

[@FabledGentleman]

It takes way longer than 2 months to lose muscle mass. It's barely noticeable in this time frame, if you are natty that is. It can take many years for earned muscle mass to vanish. I'm talking from my own experience, and friends of mine as well.

[@chaniwagh6254]

At around 5:34, you mention "the other daughter cell." Can you please explain? There are two daughter/satellite cells involved in the process of nucleus transfer? Also, what happens to a cell once it's given away its nucleus? It can contine to exist? Can it grow a new nucleus?

[@MikeServis]

“The field is the sole governing agency of the particle” ― Albert Einstein Another point worth mentioning is that the so-called material world is far less solid than it appears. Atoms consist almost entirely of empty space. If the nucleus of a hydrogen atom were to be enlarged to the size of a marble, its single electron would be a quarter of a mile away. How much do we know about this "material world?"

[@Yupppi]

Mister, you can tell me as many details as you want for context or not. I'm listening. Been following these topics by Stronger by Science and Iron Culture Podcast and this visualised educational lesson really makes my synapses fire in giving much better understanding on what all of it really means.

[@kyselinasalicylovasintramo5139]

Great video thank you very much. Could you do a video on effects of excersice on cognitive functions. I saw that Jorden Peterson talked about it a bit so I would love to know more.

I have the same condition, I recommend starting with a diagnosis by a neurologist, do an MRI, later with the results, consult a neurologist and an orthopedist. For two years I could not bend down because I ignored this problem I do not recommend

Thanks for answering a bunch of questions i was spending a lot of time online trying to find. Ill get 2nd opinions (more peer reviewed studies interpretations) as anyone should but this is a very helpful track to start on. U got my thumbs up.

Can you do a video on how our testosterone affects our body. Also, can you do a video on why old people who lift weight can no longer get big and jacked even though they lift weights . Do they lose the ability to grow muscle??

[@gatoryak7332]

Most old people are wise enough to not want to get big and jacked.

[@Jahsurfer]

Well done. How did u fix your colon problems? My plantar fasciitis went away after I started exercising my feet and gradually moved away from shoes with heel elevation to wide toe box minimalist shoes. (Note, it was a gradual process as my feet had to have time to get stronger and adapt to the flat shoes) 👍👍👍🗽🗽🗽

I am a new addicted subscriber to your channel. I would love to see explanations of what exactly happens when a person is choking and how it is caused and how the Heimlich Maneuver can save a choking person or if there are alternative options for saving someone. Also if you have any information on IBS I would love to know it. Thanks for giving us such great knowledge.

[@catsrule256]

You should make a video on what DOMS is and why it is days after workouts

I sure hope you start using the information you guys share to us about working out and start working out if you say you have all of those issues at 35 years old.

Skeletal cells clumping & working together as a multi-nucleated cell reminds me of the man-o-war. It’s not one animal, but several creatures working together to navigate the ocean, hunt/fish for prey, reproduce, and ensure survival.
