Strength vs Hypertrophy: The Science of How to Build Muscle

[@theanatomylab]

Hi All! Thank you for your comments. If you are reading this I'd love to know if you liked that we added information about the other different types of muscle tissue, or if you would have rather us just get into the skeletal muscle only. Thanks!

I like to know more about sourness after a workout. Why it happens, what does it mean, is it good or bad. Why it goes away faster if you workout or stretch after a day of rest but gets worse in 2nd or 3rd day if you don't workout at all.

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

I once saw a guy at the gym successfully lifting the most ridiculously heavy weight. If you saw him in the street, you would think he doesn't even go to the gym. He looks like an ordinary guy without much muscle mass at all. Really goes to show the difference between strength vs. hypertrophy.

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.

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.

This has been proven many times, yet wasnt included in the video.

[@Jackhammer-cw6qo]

Muscular endurance can also be trained separately from strength and hypertrophy. In strength you get more neural adaptations that can better recruit muscle cells, in endurance you get more blood vessels that can deliver more oxygen and flush out products made from reactions in the muscle to generate force.

[@evenrb]

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.

[@muhammadfaisal5Y5]

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?

[@liezl713]

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.

In philosophy, empiricism is an epistemological view which holds that true knowledge or justification comes only or primarily from sensory experience and empirical evidence.[1] It is one of several competing views within epistemology, along with rationalism and skepticism. Empiricists argue that empiricism is a more reliable method of finding the truth than purely using logical reasoning, because humans have cognitive biases and limitations which lead to errors of judgement.[2] Empiricism emphasizes the central role of empirical evidence in the formation of ideas, rather than innate ideas or traditions.[3] Empiricists may argue that traditions (or customs) arise due to relations of previous sensory experiences

Solid video! But what you have to keep in mind is that strength and size are more correlated than many people think. Yes, someone can be strong and not be very muscular and someone can be very muscular but not be that strong. But, those are two different individuals. If the same individual person gets stronger they WILL be more muscular and if they get more muscular they WILL be stronger. And by the way, strength isn't measured solely by the weight you can lift in the powerlifts. Strength is also displayed as the weight being lifted in a stable machine exercise, where the neural components don't come into play nearly as much. If you get stronger at those exercises you are absolutely building muscle. Increase your 6 rep max in any exercise over a long time period and your hypertrophy gains will be great as well. If your 6 RM doesn't increase don't expect much growth.

The CoVid lockdowns with brief periods where gym was possible taught me how to get back into shape, like 2 or 3 days for a month is enough. I managed to get myself to stay on the elliptical for 45 minutes and I have gotten more energetic. Though you have to have motivation to go really fast for longer; I usually have max resistance. My heart is between 160 and 170 bpm but it can be 120 bpm, it depend how easy going or determined I feel. It was hard the first, second or third time doing 45 minutes but I no longer thinking about it, I adapted and I could keep going after 45 minutes. I am not out of breath at all; I can sustain. I am a heavy person; like 132 kg and 171cm height. I don't want to be slim or too heavy. But I know when I was 156 kg and miraculously lost 24 kg in about a year drinking plenty of water and having a caloric deficit around 400 kcal, and watching old school MacGyver and other things, that fitness is a requirement and mobility is important, being able to walk and visit places. I was 125 kg not too long ago, but I did not want to be slim. Going to the gym counteracts the issues with being heavy. Single leg squats are good for mobility. I take vitamins, theanine, rhodiola, safron, ergothionine, DHA/EHA omega 3 close to a gram each, astaxanthin. At least 750ml of water is good for hydration each visit to the kitchen and the mental freshness. Coffee with half milk is nice in the morning, green tea half milk. Also Bolognese, whole foods, honey greek yogurt. I like to get my calorie needs out of the way. I manage my focus and relaxation. I walk the dog every morning now at 7am abouts. I do feel great. The fitness helps.

[@scott-hr3hd]

Excellent source. You are covering the essentials most fitness icons fail to touch with a few exceptions like the house of hypertrophy. Although you did not touch on strengthening tendons as what strongmen and mountain climbers work on with isometrics and slow essentrics but I would think that could be a video to itself about tendon strength, health and injury prevention/repairs or what really happens.

[@filmfrosk]

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

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?

[@filmfrosk]

@@1unsung971 Was kinda expecting to have it explained since it's literally the title of the video.

[@eduardocastaneda8369]

@@topg2820no hypertrophy could be done with just 5 reps 2 sets. Mechanical tension is what causes growth. Once your fibers feel that tension they will create a chemical reaction that creates DNA transcription which starts muscle protein synthesis. Higher reps causes more fatigue which takes off resources into growing.

[@judge831]

If you want to get big, do relatively heavy compound movements and eat 1g of protein per pound of lean body weight. Lift minimum 3 days per week. Each set should be to near failure. I like 10 reps per set. Isolation exercises are for refinement or muscle imbalances. Do them only if you must. Compound is the most efficient for over-all size.

[@rattletop]

could you do a video on tendon recovery and why it takes longer compared to muscle and bones?

[@RDS_Armwrestling]

There's NO direct bloodflow to tendons, which is why it takes longer. Tendons are trained during regular resistance training, but plyometrics and isometrics are known to place higher tension on the tendons themselves. There you go, saved you watching a video

[@EduardoMartinez-ys6fb]

As a climber I want greater strength to weight ratio or putting that another way, more strength for the same size of muscle. When exercising we don't use all of the muscle fibers. High load and lower reps will increase the number of muscle fibers we 'recruit' to perform the exercise.

"visible abs v/s usable abs"

[@thomasbenishek7927]

That’s different, visible abs is the training of the muscles next to the skin layer so you can see a nice 6 pack or obliques. Usable abs is also the training of all the other stability muscles in you core like your TVA or all the small spine stability muscles and the many many more I dont know how to name

[@danieladiaz5827]

An increase in muscle will promote fat loss through an increase in basal metabolic rate (muscle mass automatically requires more energy (calories) )

[@RealMTBAddict]

Exactly. Why am I seeing obese people bench pressing at my gym?

[@arthurfleck629]

@@danieladiaz5827Excellent points, additionally, the body can make use of fat stores to grow that muscle tissue, which will cause fat loss and muscle gain. Our bodies actually prefers to do this rather than use fat provided to it through our diet, our systems are smart like that, and their priority is to keep us healthy, so they drop the excessive and at times harmful fat stores when and wherever possible, and tough training is quite the incentive to do so. The term’s body recomposition, it’s fascinating stuff, and it’s technically a form of cannibalism, positive and healthy cannibalism of the self (if done slowly and safely, which is easier said than done), autophagy if you will.

[@richardjt8708]

Great video. And on the flip side, how does the body / muscle do things differently when it comes to endurance ? Going for a long cycle, for example, and the different adaptations between all out efforts for 1 min, 20mins and longer ? Muscle soreness as mentioned in another comment would be interesting, and from a strength and endrance point of view.

[@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.

[@BareFinn1986]

6:20 You can manipulate your heart rate to go lower by taking a deep breath and exhaling with a thin stream of air for a long time. Something about reducing preload by having a positive pressure in your thorax. I can't remember the details, but it works.

Strength wins every single time. The sooner we can defeat our ego and realize that looks don’t matter, the better stewards we can become of our own lives and can finally find happiness and contentment. I’ve never seen a “big guy” achieve something that a “regular looking guy” could not. The muscle mass is purely cosmetic.
