Strength vs Hypertrophy: The Science of Building Muscle
____
In this video, Jonathan from the Institute of Human Anatomy explores how to build muscular size. He talks about the physiology of muscular hypertrophy by discussing the changes that take place within the muscle fibers. He also talks about exercise principles and resistance training routines that stimulate hypertrophy vs strength adaptations, and even dives into the different types of muscle tissue such as cardiac, smooth, and skeletal muscle, and how these muscle tissues grow and respond to different stimuli.

I am 62 and have lifted weights since I was 15 yrs old....over the yrs, I did all kinds of weights, heavy, light, more reps, less reps and today i am on a high rep/not so high weight with all my workouts...I call this semi intense, muscle endurance exercising...my sets are hardly any rest between them and I do a whole body workout at one time....while I don't have the mass of my 30 year old self, I still have definition and I am strong for my age...I found that over the years, although my muscles got strong, it wreaked havoc on the joints in my body so therefore I am lighter weight, higher reps person for the rest of my life....there really is no need for me to throw 225 pounds on my back and squat 12 times at my age...I can do just about anything I want athletically and aren't sore for 2 days after I work out like before...I call it muscle maintaining more than anything...I was waiting for a video like this, Thanks Jonathan

[@jrg305]

I've always been a strength guy. Where people go wrong is they lift heavy too often and don't let their joints recover. I may only lift heavy once every 10-17 days. I do a lot of cardio or sport specific stuff in between and throw in a lower weight workout in between that might be closer to bodybuilders

[@chrischetwyn1539]

Been going to the gym for 20 years (natural), at my peak, i was 92kg with less than 10% body fat and was comfortably pressing 50kg dumbbells for 12+reps....but it isn't sustainable. I was up at 4am and in the gym 1.5hrs a day, 6 days a week I was in constant pain in my joints, was taking pain killers to sleep and if i moved quickly I would get shooting pains, but always wanted to try and get bigger and stronger so thought I would just live with the pain. Since I became a father I realised I needed to take the ego out of it and look at a better way of doing it. Especially being a dad took priority and don't have half as much free time, I needed a different approach. Im now testing the "Mike Mentzer routine" of less time and weight, but more slow control and intensity. I've not tested it long enough to really rate it, and obviously I've lost a bit of muscle with not living in the gym (and also age) but I still get muscle pump and fatigue etc...but just realised the other day, I've got no more pain! No more pain pills, I'm also able to move easier and play with my little boy more. So I think I'm done with the heavy ego lifting 🙃

[@gypsy_jester]

Every workout you get stronger and progress further , i also noticed that differently from high volume, where i was having pains here and there almost constantly, with HIT Its all gone, after a workout It may happen to feel something in a joint sometimes, but the days after, even if your muscles are fatigued the rest of the body is great!

[@georgieacero7043]

I believe as long as you control the eccentric contraction that is the best way to stimulate muscle, based on studies but I cannot remember the name of the article. It basically stated that the concentric must be explosive in nature and eccentric controlled - the more controlled and slower stretch you give the muscle on eccentric the better results you should see in terms of strength gain/maintenance and hypertrophy

[@christophegroulx7816]

Trust me, if you were doing the mike mentzer routine for real you would feel like dying all the time

[@brackonstudios]

And this is why I hate researching specifics on exercising and bodybuilding. One person gives a detailed description of what they do, and the results they feel, then someone (as equally as random) comes along and gives a ‘nuh-uh’. Seriously, if he’s wrong, and there’s something better, then lay out your case. Tell us why your undescribed method is better.

[@forasago]

@@christophegroulx7816 that can't be right and sounds like ego-lifting. Mike Mentzer himself preached that the muscle only starts GROWING after it's done RECOVERING. if you're in pain all the time you're never fully recovered and therefore you cannot be growing either. he was also concerned with systemic fatigue. proper rest is when the whole body rests. if you're training legs on monday and arms on tuesday you don't count tuesday as a rest day for your legs. you're still fatiguing your body so growth (in the whole body) is being delayed by that. these are all claims by Mentzer, I am merely repeating them.

Just remember that IRESTORE doesn't block the production of 5-alpha reductase and thereby stop the conversion of DHT. Just like minoxidil, an LLT-cap will promote blood circulation and prolong the anagen (growth) phase of the hair follicles. You will still lose hair at the same rate as before (even though it might not look like it at first). If you want to stop hair loss, you will need to use finasteride and, in some cases, dutasteride. Then u can regain ground with minoxidil, the LLT-cap (look for a cheaper option) and microneedling. You can also start using the ketokonazol shampoo aswell. But if you're contempt with just stopping hairloss. Finasteride and sometimes ketokonazol shampoo is enough.

[@mart34]

All my exercises are 5 sets, 30s rest between sets, 1s positive, 3s negative per rep. TUT and rest periods are precise as I listen to a metronome at 60bpm (ticking every sec), which also helps maintain perfect form. It also means all my exercises are repeatable so I can track progress in the knowledge I'm not cheating (for example speeding up the reps and not making true progress). Although my rep ranges are in the hypertrophy range, the short rest period and TUT tune my exercises more towards endurance. It works for me, I never get injuries, joint pain etc. I'm addicted to perfecting the exercises and making progress, and not ego lifting and packing on muscle and the risks associated with it. Everyone's different. All that matters is what you are interested in and what motivates you.

[@Darkrylepalaret]

Very interesting, thanks !

[@Desmondavid]

Awesome info! Could you do a video (if worth it) explaining muscular density. What is actually happening when muscles become harder and more firm? As we know hypertrophy (cellular growth) is the only phenomenon to explain muscles growing in terms of its size, but what about the hardness of firmness of a muscle? It’s still a result of hyper trophy, but why does it vary- is it genetics only? Is it the type of training? More info on this would be highly appreciated. Thank you.

[@livephysiology]

Another theory as to the magnitude of changes in both size and strength is the genetic ceiling theory. This is the idea that considering there is a limited amount of strength to be gained, there is a proportional limit to the size a muscle can gain. After all, it would not be beneficial for muscle to be able to grow infinitely, such as having a forearm that is two miles in diameter. Thus, as one gets closer to the maximal strength the muscle is capable of gaining, the size gains proportionately slow.

[@liezldoman481]

One thing that I've learned over the years of gaining muscle strength and then losing it (various reasons) repeatedly is that the higher reps exercises conditions muscles better for strength in the long run. I'm a small human (1.64m tall and just below 60kg). I've been active all my life and in 2013 I started to lift for strength. 2014 my circumstances changed and I couldn't lift anymore. I lost most of my gained strength in less than 4 months. Later, 2018 I started to lift for strength again and due to illness restricting my exercise, I lost strength really quickly again. 2022 I started working as a movement education coach and have slowly built up my strength over 2 years. I was ill last year again (chronic disease) and after 4 months I returned and lost only a very small percentage of my strength. I joined my friend at the gym the other day and I can lift heavier loads now than I could when I was gyming for strength. Just by doing little bits every day at work rather than pushing my 1 rep max like I used to.

[@katarh]

I think it was Greg Knuckols on Stronger by Science who touched on this topic recently - we do not have evidence of new muscle fiber growth contributing to hypertrophy in humans only due to the method of detection required for it (literally taking the muscle out, cutting it open, and counting the fibers), but we have it in every other animal model where we can harvest a muscle before and after the exercise intervention.

[@ElSantoLuchador]

It would be interesting to throw in a third approach, namely things like calisthenics with very high reps. They tend to be the opposite of isolation and involve many of the muscles, especially the core. The more well known of these types of exercises are pushups, planks, pullups, deep squats, etc., with reps ranging from 15 to over 100, depending. Very different outcomes than either power lifting or body building. Not the way to get huge, but the best way to develop functional strength.

[@highstax_xylophones]

Hoping this would talk about what is happening to muscle during recoup or rebuild. Have the preconceived idea that damage equals rebuild Guy lifts 50 rocks one day exhausted; guy does the same a month later easily being used to it Easiest way to think of all this is adaptation to the load.

@@RDS_Armwrestling Maybe they're interested in the science behind it rather than just an explanation?

The way I understand it, strength training helps muscle contract more forcefully with the downside of less repetition whereas, body building training helps muscle continue contracting and not fatigue. This means rest periods and volume are longer or shorter depending on your goals. Both results in increased strength but a bigger muscle cell is not necessarily required to generate more force. I have got a question though. If a muscle cell size increases, wouldn't that make it harder on the cell to function because substances are diffusing over a longer distance and myofibrils are longer? How does a cell adapts to increased fluid content?

Thank you for all your awesome videos, I was wondering why the left side of the heart gets out of sinke and stops working right ands signs the right might fail. Can you make videos on the subject

More muscle doesn’t mean more strength, therefore I chose STRENGTH

This. Massive difference between quality & quantity... hypertrophy is essentially quantity, stretching of the muscle belly... with strength you build true genuine fibers as opposed to volume/size... Not only but you'll be far more healthier & fitter as, bigger muscles are metabolically taxing & expensive

With respect to your channel, as much as I love it, Im so tired of seeing all the content(from other content creators, not just this channel, but also including this channel) on building muscle mass. Tell us more about functional strength, mobility, etc please??

[@filmfrosk]

Was hoping to learn more about the actual difference between strength and hypertrophy training, but great video! :D

[@SuperBozz]

Easy.. strength is overall conditioning my back is stronger because I develop calf and ab muscles to support it Hypertrophy is blasting a quick bicep set to grow it

Hypertrophy - high rep low weight Strength - low rep high weight

[@filmfrosk]

@@topg2820 Yes, I know that. But why is it so? Why does low rep = strength, and mid range rep = size?

[@hemanthrao9108]

Pectoral, glutius maximus and thigh muscles are the coolest... 🙂

Would love to see a video about tendon strength and how to increase it

[@missa1goins]

Stronger muscles strengthen other soft tissue and hard tissue

[@SuperBozz]

You can't exercise the tendon.. maybe a diet makes a small change However the muscles connecting them can be trained to be "quicker" and more resilient

[@kobemop]

Going slower on lifting weights trains the tendons.

My Dr. just recently asked if I worked in the medical field. Thank you institute of human anatomy.

[@davidpatterson6416]

Its good to have a mix of both strength and hypertrophy, strength for denser bones, stronger nervous system and for thicker tendons. Hypertrophy to actually look like you lift

[@wiandryadiwasistio2062]

i think what matters is _core_ strength, something i’m still struggling at. it helps balance the whole body, giving greater support to any exercises/chores we do. is there any works i can do to increase my core strength? i’m gardening and tidying my house often but i see there are only noticeable improvements on my arm and leg muscles, not back and stomach muscles

Clearly the increase in fluid for repetition/endurance training has to do with energy storage and recuperation.

[@andrewkauke]

Very informative video. It brings a question to my mind. People who do calisthenic workouts often end up with smaller amounts of muscle but still gain decent amounts of strength. These results would be in line with what you would see from strength training, yet calisthenic exercises involve very low masses and very high amounts of reps, even further down the spectrum than hypertrophy exercises are. What’s going on in that situation?

[@evilfinnigan]

One thing I have found with doing physical work on the farm, and also working with rig workers etc.., is a third type of strength. Functional strength. Someone relatively small can be very strong and the muscle looks different. It’s very dense and may be “flat” as a bodybuilder might say. Or some might say wirey lol. Good examples are amateur wrestlers, rock climbers, special forces soldiers, and physical workers. What is the mechanism here? Is it that the cells have much less water as compared to hypertrophy but still as strong? A good example of this strength disparity on KZbin is Magnus Mitbo lifting vs much larger bodybuilders. He is not a power lifter but has more strength in some areas and definitely more specific strength. He is also not a bodybuilder. Another look at this physique type is Charles Bronson as a young man. He built that with bodyweight exercises and would not look like a star of today. In myself I found in working in research where I was lifting and moving 35-100lbs repetitively, all day, and day in and day out that I became very strong but stayed around 185lbs. Some workers on the farm used to lift and handles square bales in the thousands at close to or over 100lbs each and are freakishly strong but not necessarily big. I’ve always trained to achieve this type of strength.
