17:15 Part V: Summary
Specific tension is not really an argument for sarcoplasmic hypertrophy. Muscles become more inefficient at contraction as they grow further away from the bone (larger). It's also unsurprising power athletes have way better neural pathways for contracting harder.
The study comparing 90% 1RM with 30% 1RM is more relevant, though pointless, since as you said it's not a long term analysis, as well as the fact that sarcoplasm percentage has been estimated to be a small proportion of the muscle anyways (estimates range from
Hard to imagine the amount of work that went into making this video.
Highly underrated.
Thank YOU for those kind words :)
Compared to a bikini try on haul?
I've done both powerlifting and bodybuilding. As I go to higher rep ranges my 1rm decreases because I'm not training for it, but when I go back to powerlifting and train with lower rep ranges my strength goes back up and I end up stronger. The whole it's a skill and had to be trained for me is likely the confounding factor.
I see what you're saying, but that skill needs to be consistently trained. When you train high reps, some of your skill and comfort with heavier loads may decrease, explaining why sometime training with lower reps again is required. This is me just speculating though :)
@@HouseofHypertrophy lol stupid autocorrect I was agreeing. I believe it is the the confounding factor like what you said. I was walking while posting and didn't reread it before posting. I fixed it.
With poor joints from decades of contact sports I train in a high rep range now (15-30) to good effect all around.
It supports what's left of the cartilage in my joints, develops very good muscle size and exceptional every day strength. I'm 52 years old 6ft / 240lb The only weights I use now are adjustable dumbbells.
Awesome stuff! :)
I've been investing/collecting a really nice collection of dumbbells and I love them. Rogue Fitness offers some moderately priced stuff and so far everything I've gotten seems pretty solid. I didn't realize weights were so expensive .. especially in the heavier ranges. I like the dumbbells because of the small space they occupy ... I feel like all I need are those and my small adjustable bench. I may try getting some adjustable weights, but I'm worried the mechanics might make them break eventually.
@@Fiveash-Art they've come down a lot in price since I bought mine 15 years ago adjustable from 10 to 55 lb
I’ll add that (as an even older dude) I also work on stabilizers, balance, and flexibility. I believe those will be helpful as I age. Some of my targets are the erector spinae, teres minor, soleus, anterior tibialis, and multifidus.
@@cbcsucks2205 My next pair will be 55s ... bought a pair of 50s about 3 months ago. ... Nothing beats working out in your room, watching a movie or listening to some conspiracy radio. I don't care about the gym.
Still love the way you present these. I feel like anyone could watch one of your videos and be able to keep up and apply it to their training in some way.
Thank you so much for those kind words my friend, they mean a lot to me!
Oh it’s the tier list guy 😍
I like how you mention all limitations, and to remind viewers not to take all this information to heart considering that the the topic is very nuanced and contains a lot of results that aren't completely clear to us yet.
Thank YOU, I'm continually trying to become better at making conclusions and interpreting the data :)
@@HouseofHypertrophy I sincerely applaud you for that, because it seems people take research in terms of fitness very seriously (and that’s obviously a good thing) but it really does come down to experimentation along with research, not research alone.
ABSOLUTELY AWESOME VIDEO!!! I've been interested is sarcoplasmic and myofiberal hypertrophy for a long time, but I was never sure not relevant it really was. This video was extremely insightful!
Thank YOU for the kind words, great to hear!!!
Always love the knowledge that u provide with a rlly good edit and enjoyble keep it up mate, cheers 👏🔥
Thank you my friend, I appreciate that!
As a guy with engineering background, I am very happy to see your videos. Since studies on this field are limited, it is really hard to come to a robust conclusion, however I still benefit from information in between lines you mentioned. Keep up the great work, appreciated 👍
Really appreciate these vids! It is quite useful to have comparisons between multiple studies being thorough yet easily digestible.
Thank YOU for the kind words! :)
Great video as always! Ty for dissecting these studies. I am pretty sure noone was surprised by the results but ex-science needs to step up I feel. At least we need to see a video provided to see what RIR a lot of these studies are done at. Maybe someday ex-sci guys will actually care more about studying a subject properly and less about pushing another paper out
There's many limitations for sure, and always room for improvement. But I still think many researchers do a fine job. Research is hard :)
Amazing video yet again. I began working out again after 4 years about 3 months ago. Your videos and Andrew Huberman's podcasts have made me take a whole new approach to it than before.
Thank YOU so much my friend, that means a lot to me!
Great work as always my friend. Keep it up
Thank YOU!
I really like the graphics of this channel. Well done
Thank you my friend, I appreciate that!
Excellent and clear overview, introduction, discussion and summary. I particularly like how you clarify the definitions up front. BTW recent findings suggest that strength is developed by daily training of the same muscle even if sets are as low as one.
Thank YOU for the kind words, and strength can certainly be developed with low volume and high frequency :)
Can you please tell me about these recent findings? Where can I read about these findings? Do they talk about how much volume at what intensity should the workouts be done if one trains every day?
@@incorectulpolitic Since it's research the findings are limited to the study protocols. There are several studies. All based on maximal voluntary contraction. "How much volume", as I mentioned it was one set only. Six maximal voluntary eccentric contractions five days a week on one exercise. This protocol was compared to one with 30 repetitions once a week. After four weeks both protocols showed hypertrophy, but only the five day protocol increased strength. Another study showed that performing ONE eccentric 3s repetition once a day, five days a week, during four weeks, increases isometric, concentric and eccentric strength, , but doesn't produce hypertrophy. They compared it to isometric, and concentric protocols, where the isometric only produced increased eccentric strength, and the concentric only isometric strength. In these studies the subjects were sedentary, not previously working out.
This channel is amazing!
That's very kind of you, thank YOU!
Awesome explained! Thanks for putting this out here

Thank YOU so much!
I'm really glad you brought up the illegal drug use in bodybuilders. I've worked around these people for many years and they minimize the power of illegal drugs when I'd say they are responsible for MOST of the growth in these people. Usually the biggest, most jacked guys in my gym (usually competitive bodybuilders) have the easiest looking workouts (usually fluff n pump). Meanwhile natties like myself are busting our humps for every inch gained.
Yeah, there's data showing exogenous testosterone usage WITHOUT lifting weights causes more hypertrophy than the average natty training for 10 weeks ( www.nejm.org/doi/full/10.1056/NEJM199607043350101#t=articleTop )
You'd grow more muscle on 600mg of test a week than actually exercising

Thank YOU! :)
Off topic, I think high volume training causes temporary cell swelling. Which if you stop training with high volume you will lose its effects.
The swelling may die down as you continue training with high volumes week after week anyway. But in those first few weeks, cell swelling may very much be present. In fact, in one of the studies finding sarcoplasmic hypertrophy by Haun et al. (it can be seen in the table here: 14:46 ), I think it's possible their "sarcoplasmic hypertrophy" was more so swelling as the study was only 6 weeks and they found large decreases in myofibril relative space (30%), which was much more versus the other studies.
@@HouseofHypertrophy Yes that may be also, most studies dont last very long.
@@HouseofHypertrophy How can the sacroplasm experience actual hypertrophy from training when it's non-contractible?
I don't understand the premise of this theory.
@@HouseofHypertrophy Hi, this research ignores the fact that the tendons, joints and nervous system bear the burden of load in Heavy Low rep ranges, but the muscles bear the burden of load in Light High rep ranges.
This means that the joints, tendons and nervous system assist the muscles with heavy lifting. Hence, this is not a fair comparison.
So how can you break your muscles down to rebuild bigger muscles? I was thinking high volume will help build muscles.
Great videos. Keep it up !
Thank YOU! :)
This is quite interesting! Great video!
Awesome to hear, thank you!
Perhaps this is true, I typically tend to lift in the 8-15 rep range. I have had to take the past 4 months off due to an elbow injury (didn't happen while weight lifting). I've lost most of my size entirely (wasn't small). I've always liked high volume training with a lower weight, since I found in my early 20's I'd get hurt more frequently with higher weight. So I reduced the weight, increased the reps and just focused on being able to lift weights long term.
Same, doing a 1 rep max is dodgy af, i dnt think i ever met an older powerlifter who wasnt full of injurys, so far ive kept myself relatively injury free doing exactly 8-15 on 99% of my lifts ! and im in my 40s.
So how long have you been lifting for and what is your 1rm on compound movements like bench and squats?@@mcpartridgeboy

This is my favorite however channel
Haha :)
The best YT canal for muscle hypertrophy and studies,also i would like to see video about best diet for muscle hypertrophy.👍
Thank YOU my friend, that's very kind of you :)
Good video. What i found from this studies is that bodybuilding training produce overall more muscle and strength, but power training produce more strenght per size of the body. So if you want to be big and strong you should train like a bodybuilder and if you want to look small, but have more strength that is expected from you, then you should train power style.
Wow what an insightful presentation
That's very kind of you, thank YOU!
I think that what probably matters the most is how close to failure someone is training rather than the rep range as long as it’s less than 20 or 25 reps.
Henneman’s size principle and increasing tension per rep until failure will recruit all muscle fibers. I think there’s more to it than this but simplified I don’t think there is such thing as dense muscle. Maybe matured muscle that’s been through the ringer.
Yeah, I see what you're saying. At the fiber level though, it's possible more contractile growth over sarcoplasm growth creates a denser muscle apperance, but to what degree and how much has definitely not been explored by the literature :)
1:19 "damn, u strong" made me chuckle 😂
Haha, I was hoping someone would notice that! :)
High reps may increase the sarcoplasma size due to higher need for glycogen storage. Also power lifters focus A LOT on producing power rather than just doing the reps, neurological parameters needs to be researched. Awesome video! Ty for everything.
Great channel , love the passion and effort u put into your work .
Thank you so much my friend, I truly appreciate this :)
The whole "hard vs puffy" muscle appearance may have more to do with residual muscle tension (aka muscle tone) than the structure of the muscle. Basically, your muscles are always partially flexed, and residual muscle tension is just an indicator of how much they're flexed at rest. I've noticed that heavy sets leave my muscles a lot harder, sometimes for days.
Good observation, there can also be body fat differences between people that cause muscles to look soft.
Agree, muscle "should" look soft when fully rested, they are 79% water on average. after all Jay Cutler legendary Quad Stomp is a good example, his muscles "jiggle" a bit until he flexes them.
turns out "toning" was real after all - this is increased residual muscle tone
I remember Pavel in his book 'Power to the People' touting this hard look due to muscle tension as a good thing, but is it? Should we be all tensed up? It's the nerves after all which would keep the muscles partially tensed, which might mean that the body is anticipating danger
Tonus is residual tension in "relaxed" muscle tissue. Like when you wake up in the middle of the night and happen to touch your relaxed vastus lateralis and it feels as hard as iron. But do a long layoff, and after a couple of weeks that leg feels like eel shit, mushy and soft.
0:00 . I was hoping for "bem vindo". As always, another incredible video!!
I'll add it into a future video :)
seriously such an underrated channel.
Thank you my friend! :)
Very good video
What I’ve never understood is why we try and limit ourselves to one rep range. It becomes like a competition. This rep range is “better than” the other rep range. Almost like we then miss the woods from the trees, as the saying goes. We can, it has been proven, that we can make gains using almost any rep range. It depends on the muscle group being trained and the ratio of slow twitch to fast twitch muscle fibres as to the possible rep range which would be best for a particular muscle group. Everyone is different, however the point I’m making is surely it makes more sense to train with a variety of rep ranges, changing things from month to month, week to week or even workout to workout. Rather than deciding that say 6-10 reps is best and never straying from it.
I’ve certainly found I’ve benefited greatly from implementing a wide variety of rep ranges from strength training in 1-3 rep ranges to conditioning, such as 30 reps even higher. Basically getting the full benefits of all rep ranges and improving greatly from it. Just my two cents.
I agree with you, the upcoming video on Monday will address the variety of benefits one can attain from using a variety of rep ranges :)
I like low reps of 3 using controlled movement with a moderate weight to both stimulate the muscles and feeling intensity every 7 to 10 days, this has produced excellent results for me.
Every 7-10 days?? How many sets do you do in one session?
Really great video again. Do you have any videos that deal specifically with the concept of overtraining? Is it really possible for a normal person to train so much that it actually hinders their progress or is more almost always better?
I appreciate that my friend!
I don't have any current videos on overtraining, but I do plan to eventually. I'm going to dive into that literature more at some point. At this point in time, I believe overtraining in some form is certainly possible for natural indivduals. The question though is that point far greater than most people presume. Also, other factors such as indivdual differences, diet, sleep, stress, etc. also factor in, so I think it's probably quite a nuanced area overall.
@@HouseofHypertrophy Apt, apt Analysis.
I think it is more likely to happen with athletes who play, train, and practice as they have to find a balance. Basically, pushing their bodies close to failure in a sense.
For us normals, I think we’re more likely to be under recovered. I guess CrossFit begs to differ but during their hype days in 2014, they were just doing random workouts of the day so it wasn’t really training with a goal. To me, they were just exercising, which isn’t training.
"Is it really possible for a normal person to train so much that it actually hinders their progress" - depends on what you consider "overtraining" and what you consider "progress".
First, yes, it is very possible to train too much. Not that hard, actually, a lot of people can unknowingly do it.
Second. Define progress. You can even train every day and have progress, but it doesn't mean it is the best time efficient method, and doesn't mean you will see that progress immediately. Usually if your frequency is too high your muscles are not repaired 100% every time you train, so if you wanted to see and measure the full extent of your "progress" after such type of training, you will need to rest eventually.
Third. You will have a lot higher risk of getting overuse injury(tendonitis) if you overtrain unprepared. But, you can train a lot more the more you accustom your body(and especially tendons) to it.
So in conclusion - highly depends on the person in question. Possible to overtrain? Very easy for most people. Training is a spectrum. The most (hypertrophy?) gains seems to be in the middle(just the right intensity/frequency), while undertraining and overtraining to some extent will also work, but not that great. If you go too far right(into the overtraining) you will either get injured or have no progress or even lose muscle(in worst case). But if you progressively up the intensity/frequency, a human body is capable of doing far more things than you can imagine. So if you really wanted to, you can go into the "overtraining" territory, without getting too far as to injuring yourself, but this is a hard thing to manage for little to no real benefit.
yeah id like to know as well, im new to the gym and have almost finished a 10 week block of doing full body three times a week, but i spend 2 and a half hours in the gym each session and feel im probably doing to much even though i do feel particularly over worked by the sessions, just satisfied with my effort etc. that being said i really dont know what im doing at this stage ? i am overweight at 112.5kgs and what seems to be happening is that the weight isnt really changing but i do feel new muscle seems to be growing all over my body and eating up the fat (im not calorie counting yet) . when this week finishes im going to take two weeks off and do lots of research on 4 day splits, as i really dont want to over do things if its actually detrimental to what im trying to achieve yeah ?
it just feels like im not actually doing much when i cut the session down to 8-10 excercises so i just keep adding other stuff yeah lol
I have, for lack of a better term, described to trainees that the muscles are not only muscle fibers, but have a "container" component. Ronnie Coleman did 75 reps with 225lbs on the bench press, Ronnie had very big containers to store enough fuel to do that kind of work output. The weight lifters do very, very, short work sets which do not require high work output aka "power".
Power is short bursts, like power lifting
Bodybuilding is bot for power
@@Percules15 power is actually an equation, which divides mass moved by a factor of time.
@@Percules15 P= W/^T
The summary at the end is great
Awesome to hear! :)
From my own experimentation I always like training 12-15 reps the best. So glad to know it has no real downside.
Awesome stuff! :)
So long as it's 12-15 *struggle reps!* Those last few reps have to take you to hell and back for that range to be effective, however, if they do, and you compound 2 or 3 more exercises of that scheme, you will grow *phenomenally* in both strength and size (obviously size moreso since 12-15 rep schemes are volume sets).

Why not both? This is what I love about the Bioneer's approach. It's focused on function over aesthetics, but of course form follows function. It will make you bigger. It focuses primarily on strength endurance, but it trains your muscles in basically all the ways you can. Start with overcoming isometrics. Then mechanical drop sets, aiming for a number of reps that's 20~50 or more depending on the exercise. But I try to do the hardest exercise I can (might be plyometric, or advanced calisthenics like planche pushups), and I often end up able to do only do a number of reps that's in the strength range, like 6 or less. Then immediately switch to an easier progression or different exercise that works the same muscles and do as many as you can, which for me often ends up being in exactly the bodybuilder rep range. Then switch to an even easier version etc until you can complete a total target number of reps that's in the strength endurance range. Only 2 sets, but then you'll do several others that use basically the same muscles in different ways. And finish the workout with a quasi-isometric, like a 1-minute long pushup. So you'll have done lots of different exercises and trained at every point on the force-velocity curve, having done strength, hypertrophy, and endurance. Strength endurance is often overlooked because everyone wants to look more buff, but an argument to made that it's more useful everyday strength than your one-rep max, is better for your connective tissues etc. But with this approach, you can do all the kinds of strength training in way that's interesting and fun with a lot of variety, in a workout that takes a little over an hour. If you want to be a powerlifter or bodybuilder of course, then train for that. But if you want overall fitness and athleticism, longevity, everyday functional strength etc, and want a better physique but aren't desperate to look like the Hulk, I think it pays to be a jack of all trades.
This is very interesting. I’m gonna start doing this. It makes sense to train both high reps and low reps. And also the super slow reps as you listed above w the 1 min push up. So I should search “Bioneers approach”? To get the info
And would maybe doing a 2:1:1 method in terms of weeks in the month? 1 week strength; 1 week hypertrophic, 1 week strength training, 1 week endurance, repeat?
@@daysl33per I don't know... I switched back to Gymnastic Bodies, because I realized I'd never be able to do a planche etc with a split like that, and with so much time spent on endurance, I had none left for stretching.

Everybody’s a scientist
For upper grade hypertrophy one suggested mechanism is the inside of myofibril packaging issue.
Force output decreases when the actin and myosin are too densely packed inside the myofibril.

Thank you :)
Thanks again 😊
No problem, thank YOU!
This is one of those things that I'll always believe is a myth. Thanks also for pointing out the limitations in comparing "strength" when the test is done in a way that favors a sport-specific method. So many people are getting tripped-up by this.
Agreed! :)
I believe cardiorespiratory capacity can best be developed using multi-joint exercises that are a moderate to heavy load. So It is ALL about intensity . I developed a Training method that goes like this: I perform five sets of an exercise. In the first set it's just activation I do 15 and 20 repetitions until close to failure. Second set and third set I do 8 to 12 reps more load.. In the fourth series I get heavier about six reps and go drop set or rest pause.And finally in fifth grade I do a minute non-stop. Rest about 2 minutes. 8-10 sets muscle/ workout. Great progress strength and HIPERTROFy
Nice!

Saludos House of hypertrophy from USA ❤❤❤
This is an extremely helpful video, but I have a question. what if I was to focus more on muscle size (more sarcoplasm) and after around 3 years, I start to incorporate heavy strength training? Would the amount of sarcoplasm decrease or stay relatively the same?
I think Sarcoplasm assists muscular endurance . Sarcoplasm stores ATP in it so maybe higher reps tell the body that it needs better muscular endurance and starts to undergo sarcoplasmic hypertrophy. Which would explain how body builders have more sarcoplasm as their repetitions are higher.
And also look at cyclists legs. Cycling is more so an endurance sport(I think) but they have huge legs
Yeah that's possible, though I should note as mentioned in this video, higher reps per se don't seem to cause sarcoplasmic hypertrophy, rather perhaps high volumes :)
@@KtWrldGaming distance cyclists / climbing specialists don't have huge legs neither do long distance runners. The cyclists with the huge legs are usually only the sprinters or time trail specialists and they also do a lot of strength training like squatting
Celll never ever store atp it used immediately
I co-sign this, it’s been my secret sauce. I’m fat now trying to lose weight, but when I was lean, I was huge as the juicers and half as strong on the strong lifts, because I used serge nubrets pump method of training. Very light weights, done very fast, with very little rest between sets. The secret is, you never go to failure, you’re hitting hundreds of reps per muscle group per session, and I added in 5 pounds or 2.5 pounds to exercises when I could do the 8x12-15 reps or the 6x12-15 reps with a rest of only 30-60 seconds. If you cannot complete the reps it’s too heavy to get a proper pump, if you cannot get the pump, You won’t get the results. You will never hurt yourself training like this, you will get stronger just slower, you will build a very aesthetic full muscle, and your conditioning will be through the roof! Just keep your diet under control if you’re a natty, because you’ll want to eat everything if you actually hit it 6 days a week 2 splits a day. Modify nubrets program, some of those exercises have been long since debunked, so replace them with solid ones. Good will hunting brothers in gainz 💪🏿💪🏿💪🏿!
Wow you give me a lot to think about!
Yeah but youll look massive but youll be weak for the size you look , you will look like your really strong but your not that strong as opposed to looking small and weak but being incredibly strong
Am I right or wrong in thinking that myofibrillar muscles are representative of our fast-twitch fibres and sarcoplasmic muscle for slow-twitch fibres? And if this is true could that be a reason as to why there is no definitive answer for selective rep ranges/exercises being the sole contributer to either myofibrillar/sarcoplasmic hypertrophy?
All muscle fibers have myofibrils and sarcoplasm, but whether myofibrillar hypertrohy occurs more so in fast twitch fibers and sarcoplasmic hypertrohphy in slow twitch fibers is difficult to determine as the evidence has not properly explored it, but I think it's a great question and suggestion :)
I don't want to confuse anybody. I just want to make sure I understood it right. Do you mean with high(er) volume more sets or more weight in general. Both could be the answer, too, though.
But in general, I'm grateful that you make such interesting videos that aren't hard to understand. 😊
Many bodybuilders go to the gym multiple times a day so the total weekly volume per muscle group amount would be massive, thus indicating sarcoplasmic hypertrophy. Still sceptical about which rep ranges lean more toward myofibrils and sarcoplasm size until research is done in the rep ranges at 1-6.
Thanks!
Hey, thank YOU so much for the donation!
I always drop set start heavy then drop to light for the reps. Always did both
I suggest adding another limitation: there is no direct evidence to even suggest that there is something like sarkoplasmic or myodibrillar hypertrophy. Or I missed it in the video. The things you showed were all correlational in nature and confounded by neural adaptation (where I actually don't have proof for either)
It would need a study to assess actual muscle fibers after a specific training regimen to show that these concepts exist.
I like your style of video production! It is calm and very nuanced. Please keep it on :)
Thank YOU for the kind words!
In the video we did detail studies that have directly measured myofibrillar hypertrophy or sarcoplasmic hypertrophy. The myofibrillar hypertrophy studies are shown here: 10:22
The sarcoplasmic hypertrophy studies are detailed here: 14:50
Okay seems like I missed it then ^^' thanks for your response
I think the reason why higher rep ranges mean more hypertrophy, is that usually…..when you lower the weight, your increase reps, and increase sets, because full fatigue hasn’t been reached as quickly, as lower reps and sets with heavy weight
Is there a place where I can read good articles on fitness & science of various techniques in general?
Let's see what class has in store today!
Haha, hope you enjoy the video and found it interesting in some way! :)
Bench press pdf is very helpful 👍
Awesome to hear, thank YOU for checking it out :)
So should I always train with at least 90% of 1RM for hypertrophy & dense muscles ? Or what will is the best strategy to create my training program ?
Nah, as mentioned in the video, for hypertrophy, reps between 6 and 35 are similarly effective per set :)
Wow, just wow!
:)
muscle fiber plays a role too. Type 2x achieve myofibrillar hypertrophy in the 1-5 rep range ( under 8s of >90%max). Type 2 glycolitic fibers achieve myofibrillar hypertrophy at 12 rep ranges. Slow twitch fibers achieve myofibrillar hypertrophy at 35reps. This is all according to Barry Ross in his book on strength training for speed.
Not sure I agree with that, simply because there's no evidence to support it. It could be correct, but in the absence of concrete data I'm skeptical
@@HouseofHypertrophy I think he is basing it on the fact that the different muscle fibers use different energy systems and we know how long the energy systems last so is deducing how many heavy reps you can approximately do in that time frame.
@@zber9043 yes but once you approach failure every muscle fiber/type is going to be exhausted, it would be stupid for your body not to recruit everything.
It would be interesting to know if diet also plays a role, most bodybuilders have a higher carbohydrate intake throughout the day and during training.
That's a great question! I think high carb intake can certainly increase glycogen stores in muscle fibers, hence resulting in additional fluid into the fiber. So technically I think it can, but whether this difference is notable and enough to induce sarcoplasmic hypertrophy is certainly questionable
My farther and me, we are dense type peoples, so that's where I focus myself on and I realized if I also increase the numbers of sets with the same weight, for example doing it 5 times vs like 3 times, I feel a sudden increase in endurance strength. So our type is a little stubborn before you can move on to more weights
Good thought
I love how the flags from all the studies are color-coordinated.
:)
Would it be best for every workout to train the muscles with low reps heavy weights first and then switch to higher reps low weight? Does heavy weight low reps work for isolation exercises if you can do it without injury?
8 reps to failure is the best of both world for compound exercise imo
5 reps to failure is also great for isolation, i do it sometimes on triceps and biceps
The only muscle imo that don’t really benefits from heavy lift is side delts
It depends on your goals, combining rep ranges can certainly be perfectly fine!
Heavy weight with isolation could probably work, but it also depends on how heavy? 6-8 reps on biceps and triceps exercises is fine imo

@@HouseofHypertrophy My goal is maximum size and strength. I don't care about relative strength or strength to weight ratio.
In general, bodybuilders tend to rest less between sets compared to power athletes. There might be a relationship resting time between sets and sarcoplasmic hypertrophy. Is there any study about this topic?
That's a great point too, unfortunately there's no data on this that I know of :(
Rn I do first set light second medium around 6-8 reps and last set to failure 5reps max is that good? Will I look more aesthetic or bulky also I am lean
Good 👍
Appreciate that!
A bit unrelated but I'm curious what stretching in between sets can do for hypertrophy if anything. It just feels good to me to do it, seems to help my next set but it might all be in my head. Excellent video.
Data is very mixed at the moment on this. I have a previous videeo it: th-cam.com/video/9dlwvYq26NA/w-d-xo.html
There's another study that's been released since that video, indicating calf stretching between calf raise sets slighly enhances solues growth (but not really gastrconemius growth) - pubmed.ncbi.nlm.nih.gov/36048793/
I will likely make an updated video including this new study at some point :)
@@HouseofHypertrophy Neato! Thank you for your hard work, the editing has come a long way in only a year. Way more fluid and easy to digest, love it.
Really awesome to hear, than you :)
Powerlifters' and other power athletes' strenght and explosiveness is also influenced by the better development of their nervous system as a result of the specific training. Doesn't explain the better specific tension of the untrained individuals in that one study , of course.
Yep! though I should note specific tension is measured outside the body, so neural adaptations does not confound this (so the English study does not involve this limitation). However, the Japenese study does have this limitation, they did not measure specific tension, rather ratio of triceps size to strength
It could be that the fibre gives strength and is fueled through the sarcoplasmic proteins. So when you tire out the strength of the muscle the fibres grow but of you tire the energy around the fibres in protein they grow? Or am I totally wrong
The sarcoplasmic proteins are certainly involved in generating energy required for various reactions in muscle fibers, so I don't think you're wrong. High volumes could just be very anaerobically taxing such that they elict an increase in sarcoplasmic proteins (hence why high volumes may cause sarcoplasmic hypertrophy)
@@HouseofHypertrophy that's what I thought or they run out more of the feeder proteins rather than the maximally emphasizing strength fiber
I wonder how time between sets affects the different hypertrophys. I usually rest for 2-4 min between sets, to make sure I can get maximum reps. I generally experience little hypertrophy, however my strength has been increasing.
Yea If I don’t take a break like that I get gassed out in a few sets
Dorian Yates had the hardest/ more dense muscles I've seen in a BB, and he was training around 6-8 reps.That might be the sweet spot for both strength/hypertrophy (5-6 reps most likely).
5-6 reps opr even 6-8 reps are certainly a good crossover between strength and hypertrophy :)
Love this
At 10:37, all findings of the studies involve an increase in vastus lateralis fiber CSA but no effect on its specific tension.Doesn't that suggest a more puffy muscle (sarcoplasmic hypertrophy) proving the point made in Part I?
It is also dependent on nutrition
It would be nice to also study the nutrition if provided in these studies.
one question would it be wise to do lower reps for larger muscle groups (chest shoulders back legs) and higher reps for smaller muscle groups (biceps, tris, abs etc.)
It can be a fine thing to do! I don't think it has any inherent muscle hypertrophy benefit though
Will these principles work same for bodyweight training also? And if not then how can I further optimize it.
I believe all this will apply to bodyweight training :)
So I wonder about drugged lifters, specifically 'mass monster' types who are training for pure size and as far as I am aware of it typically go for very high reps and volume.
It's also commonly said that drugged lifters lose their gains, I wonder about if this is due to the sarcoplasmic component of the size. Any information on the query?
PS. Oh I see that you do cover this, lesson learned: wait til the end.
What about explosive movements like box jumps or clapping pushups, was that included in these tests or did I miss it? Or does it matter?
They were not involved in these studies :)
I have a question. What if I did 2 excercises squats and leg extension, qith the first one going heavy for triples and the second one lighter for 12 reps. Is that good or not?
There's nothing inherently wrong with that :)
Triples may not be the most efficient for hypertrohy, but if you're main goal is to develop strength with the squat, triples can be excellent :)
Ok so after all that, just more sets, got it
Hi if we train for srrength then how many sets per week because we only do 1-5rep per set for strength
Have they ever done a study where they use different training methods with the same person? Like perhaps have them use low reps on one arm and high reps on another arm.
Yep, there are a few out there that do this! For example the study detailed in this video did: th-cam.com/video/tuF40f90tCQ/w-d-xo.html
There is clear research that shows different rep ranges affect different kinds of hypertrophy. Not sure why it’s always left out
I want both
Interesting comments below consistent with body building being primarily for a particular appearance, and for the particular type of strength measured by... lifting a weight once.
For functional fitness (stamina activities like running, swimming, climbing, physical work and sports that keep you on the field more or less continuously for hours) higher reps appear much better. Long, high volume workouts are also somewhat aerobic of themselves. Sarcoplasmic hypertrophy might just be an adaptation to increase muscle food (glycogen) stores within muscles next to the myofibrils.
All good points!
I think having a lot of bulk would naturally cause less strength per fibre (aka specific tension), as it all kind of gets in the way, as opposed to what they're saying (it has everything to do with myofibril density).
It depends on what's causing that bulk. If it's actual contractile tissue (myofibrillar density), there's reason to believe it would not cause less strength per fiber, whereas if it's more sarcoplasm, strength per fiber would be lower
i have a doubt, can sarcoplasmic hypotrophy can be reversed?and how? and how can i change it to myofibular hypotrphy
