    Why is this article showing up on New Year's Day like the flock of newbie gym customers attracted to the gym only to quit 30 days from now? Every year without fail.

    Let's ignore this article for a moment.

    Overall factors that REALLY matter building muscle: 1. Consistency - Working out each muscle group at least once a week....every week. 2. Diet - Making sure you are consuming enough protein in your diet, approximately 1gram/pound of body weight...or near it or even best you can. Total calories consumed a day should match any online calculator for your age and activity level. 3. Sleep! 4. Sleep! 5. Vary your workout - some weeks high reps low weight and some weeks low reps high weight. Why? Never let your body know what you're doing and shock it as best you can. Always try to exert yourself enough to be sore within 48 hours of a workout.

    Now multiply this over a few years.

    Stop reading these studies thinking there is some optimal way! It's just hard work over time.

    BTW: In winter I bench press 350 pounds or 159KG. I run 10KM or 6.1 miles twice a week and increase it a little bit in summer. I pull my body in two different directions because I love both.

      This is a physiology research article published in a physiology journal, not a Tiktoken influencer peddling "get ripped fast" schemes.

      In an ironic twist, you then proceed to peddle your own. In a single paragraph you added more contentious "advice" than in the entire article you're dismissing.

      > Stop reading these studies thinking there is some optimal way! It's just hard work over time.

      "Hard work" and "learning new things" are not mutually exclusive. Stop presuming you know what I think while I'm reading these studies.

      The muscle "shock" broscience has been disproven many times:

        Indeed. It is really just tension x time under tension within a sensible rep range (probably around 5 - 30 reps or so). Menno on Youtube has a bunch of videos on this, the link below being the latest one.

        https://www.youtube.com/watch?v=rmOBmTZARq8

        Basically work the muscle harder and get more jacked. It isn't that hard. Full body workouts are also great for this reason: you can hit a muscle more times per week and be fresher when you hit that muscle, so both the tension and time under tension can be higher vs a body part split.

        • CuriouslyC 4 minutes ago
          Time under tension is an imperfect measure, it's just less bad than other measures we could use. Sort of like lines of code in software engineering. Given that, saying it's "just TUT" is misleading.

          It could turn out to be that the brain is coordinating hypertrophic biochemical cascades in muscles, and TUT is just a fairly reliable method for inducing this.

          I was a competitive powerlifter and trained around pro bodybuilders for years, and in my experience, the only commonality between them was the intense all consuming drive to be absolutely monstrous (and they ate a lot). Some would train for 2 hours a day, some would train for 45 minutes 3x a week, some would use high volume in the 50-70% range and others would focus on 70-85%, some were explosive some were slow and steady, really it was all over the map.

        It doesn’t really affect hypertrophy but it matters because imbalances will get you weird injuries and/or mobility restrictions in the long term.
    • swalsh 1 hour ago
      "approximately 1gram/pound of body weight"

      I believe this should be lean mass, not total mass. I think people tried to calibrate this metric since most people don't have scales that can measure composition... but if you're obese, you're going to be consuming more than you need to, which is counter productive if you're obese.

      • ffsm8 1 hour ago
        It's actually not, because nothing provides as much satiety as protein.

        Every calorie you get from protein reduces your cravings for food significantly more then the equivalent carb and fats.

        You still need to get over the initial insulin normalization though from reducing sugars. Nothing reduces that pain, no matter what you try.

        • MegaDeKay 30 minutes ago
          Protein is more satiating "if and only if you are not getting enough protein for optimum body recomposition" which Menno in another video puts at 0.8g per lb of body mass.

          https://www.youtube.com/watch?v=YHLXank1PPk

          Menno's videos are exceptional: science based and backed up by common sense.

      I just got back from the gym and it was surprisingly empty. Actually, more empty than normal.

      My experience from lifting now for 30+ years and seeing thousands of people lift is it is: 1. Genetics.

      Everything else is a distant second or third. This was actually something that was widely understood in 90s bodybuilding magazines. Lifting is mostly a display of genetics. That worked when you could sell magazines of genetic freaks working out. Without the magazines you have to sell all this nonsense like 1 gram per lb of protein. Even though I know the early research was 1 gram per kilo and then Americans just changed that to 1 gram per lb. I mean it is just such obvious nonsense that the optimal amount would happen to be the exact integer amount vs body weight that is easiest to remember, how convenient for people who sell protein lol. duh.

        It really is just mostly this, and social media has tricked people into thinking otherwise.

        I was looking at some photos of myself about 10 years ago. At the time, I had been hitting the gym hard, consistently, and intelligently. I had a huge bench press, squad, and deadlift, and was lifting 4-5 days a week, and managed every facet of my diet.

        Now, I'm older, have kids, don't sleep as much, and definitely don't make it to the gym as much. I might lift twice a week - and don't try very hard or do progressive overload at all - and try to get in 3-4 days of cardio.

        And I honestly don't look very different. Muscles are roughly the same size. In clothes, most people wouldn't be able to tell the difference.

        • patmorgan23 2 minutes ago
          Counter argument, muscle maintenance is a lot easier than muscle growth. Of course you don't look that different now, you have done enough work to significantly change your physique, but done plenty to maintain.
      • h2zizzle 42 minutes ago
        Can sort of confirm. I wouldn't say so much "genetics" as "constitution". That is, you're born with a set of attributes, and those can also be affected by circumstances outside of your control. Those come together to determine how you respond to exercise and whether you can exercise consistently at all. Someone with active and athletic parents who was affected by undiagnosed childhood diseases and poorly managed injuries (*cough*) is going to have health and performance problems that keep them out of the gym. Someone who builds muscle very slowly but who can just keep at it for 10, 15 years is going to be jacked.

        We also don't account for the role of money in these things. Do you make enough to buy good food, afford a decent gym that you can visit regularly, afford a good doctor who can help you manage issues (such as, ahem, low testosterone)?, afford a low-uncontrolled-stress lifestyle? You're good. It's a lot harder when you get hit by roadblocks and don't have the money to resolve them before you've detrained.

    Yeah this is why. Anything you do as an untrained person is going to get you newbie gains. It's just really easy to improve initially. Doesn't mean it'll work after the first 6 months

        > it is possible that the type I fibers of subjects were underdeveloped in comparison with the type II fibers as a result of training methodologies. The type I fibers therefore may have had a greater potential for growth compared with the type II fibers

        Maybe a mix of both types of training would be best then?

    • timr 9 hours ago
      Perhaps there's some unmeasured influence, but this study was looking only at the difference between growth within subjects vs between subjects. If the subjects were all "newbies", then that doesn't explain the results.

      They're essentially saying that individual genetics explain the majority of the variation seen as a response to muscle stimulus in their test subjects, not the mass used, because the variation within the test cohorts was greater than the variation between them. You can argue that, if they didn't test experienced lifters the results might be different in that population, but you can't dismiss the results on those grounds.

      • raducu 8 hours ago
        > not the mass used.

        Completely anecdotal, but when I was 18, in highschool, I trained in the gym in my hometown, supervised with a trainer, 12 reps per muscle group, very modest gains.

        I move to university, start reading a fitness forum where people were saying do max 6 reps if you want big gains.

        I also started supplementing with whey protein, and within 3 months the gains were spectacular, everybody noticed, I felt on fire, best time of my life, I miss so much how great I felt in my own body.

        I've seen other colleagues and how they trained -- I can say there was 100% correlation that those people who were not training hard also did not have big gains. People who had enough breath left in them to chat in the gym simply did not gain as much as people I saw as training hard.

        Also for me, the 6 reps to exhaustion felt completely different then 12 reps (again, to complete exhaustion) -- immediately after the training it felt amazing to be alive, the world became a comfortable place, my anxiety completely vanished, and in the night and morning after an intense training (especially the legs and back) the erections and libido boost were out of this world, something I never felt with the 12 reps regimen.

        • vidarh 4 hours ago
          What do you consider gains? Consider that this paper looked specifically at hypertrophy (size), not strength. While they correlate, training for one or the other can be very different..

          "Traditionally" the rep ranges recommended for hypertrophy has typically been significantly higher than the ranges recommended for strength, but the number of sets recommended is often also significantly higher, often translating to significantly higher total volume.

          > I've seen other colleagues and how they trained -- I can say there was 100% correlation that those people who were not training hard also did not have big gains. People who had enough breath left in them to chat in the gym simply did not gain as much as people I saw as training hard.

          Well, yes, but training with lower weights and higher rep ranges does not automatically translate to "not training hard".

          Having gone through a period of really high rep training, including for a short period doing 1000 squats per day as an experiment, mostly bodyweight, that was far harder exercise than when I 1RM'd 200kg. But the effects are different.

          I much prefer Stronglifts and Madcow but because I favour strength over size, and it's far more time efficient, not because you can't also get results with more, lower-weight reps.

            I'm not sure where this idea came from that people do one or the other. Except for the advanced lifter, both will happen from either program. Show me a person who is really big and they are likely pretty strong as well (see Ronnie Coleman). Same with the other direction.

            • ffsm8 46 minutes ago
              I'm not a fitness nerd by any means, but it's worth mentioning that your bodys ability to get oxygen to you muscle can reportedly easily become your bottleneck if you're training too once-sidedly or use performance enhancing drugs/steroids.

              So the bulkier person could theoretically perform better, but doesn't in practice because their body isn't able to actually utilize the muscle effectively.

              That's why farmers often outperform lifters outside of the exact niche the lifter trained

              I did not at all suggest anything else. Both will happen, but not too the same extent. It doesn't take very much lifting before differences in training regime can be apparent.
        • bendtb 8 hours ago
          Anecdotally as someone who strength trained on a recreational basis the last 20 years (and run a marathon just to see if I could), nothing beats heavy lifting.

          A Strong lifts 5x5 program build around squat, deadlifts, bench and shoulder press can always make me feel pumped for the day!

          • matwood 5 hours ago
            Same. Finding heavy lifting changed my life if I’m honest. The strength gains, body comp, and how I felt was amazing.

          IDK. When I powerlifted the goal was to move the weight. I've almost passed out from heavy deadlifts, but was rarely out of breath. I also almost never chat in the gym because it's my meditative place, not because I couldn't chat :)

          • hunter-gatherer 3 hours ago
            I think what OP is specifically refering to is the intensity level that varies among individuals. I suspect that oft times when people train with a low weight/high rep scheme, they accidenrly let their intensity levels slip. I suspect that for most people, especially newer lifters, doing a high weight/low rep scheme makes keeping the workout for intense because it is easier to focus on being intense for a short time. Just a thought....
        • marknutter 54 minutes ago
          There really isn't much of a difference between doing 6 reps vs 12 reps, what matters is going to failure which I think may end up being harder when doing 12 reps because people maybe don't realize how much they have left in the tank.
          • bonesss 26 minutes ago
            Going to failure can also be a question of which ‘link in the chain’ is hitting failure at any given rep range.

            Bent over rows being and easy example: at a 5RM upper back is giving out as desired, but past 10RM my lower back is the issue. If my goals are bent over endurance in my core then higher reps will force adaptations where I’m weak, if I’m trying to get my shoulder blades sexy and humpy I gotta keep the stimulus where I want results. In addition to manipulating reps something like a snatch grip can provide a leverage based answer to the same targeting needs.

            Proximity to failure is key, targeting and maximizing that proximity is individual and highly goal dependant.

            [As a bit of a physio case I’ve found General Gainz (/r/gzcl on Reddit), to be a highly productive RPE based system with very happy adaptive approach to hitting personal limitations mid workout; no “failures” or broken spreadsheets = motivation = consistency = progress; strong recommend to check out]

        • eastbound 1 hour ago
          Why did you stop? It seems you did, but since it made you feel excellent, it seems strange to “choose to stop”.

          It’s not an innocent question: Gains and feeling extremely well and confident and serotonin-boosted are only useful if it can be sustained in life. The two alternatives are: 1. It pumps you but tires you very fast and you get fat down the line, and your overall life is ~obese (seems to happen to way more people than one could assume), 2. Only the change produces this feeling, and change cannot be sustained forever.

      • sedivy94 8 hours ago
        The activation energy or stimulus required for hypertrophy in untrained individuals is so low that it’s hard to differentiate the results. Studies like this absolutely need to be done in trained individuals if you want reliable data.
        • bluGill 6 hours ago
          Most people are untrained so this is useful reliable data for most people. However for those who actually care about results: they are trained, or soon will be andthis data doesn't apply.
    • foldingmoney 11 hours ago
      exactly. when you're new, virtually any type of lifting you do is going to create sufficient stimulus to trigger maximum muscle growth, because you're going from 0 to 1. unfortunately, since the only people that researchers can usually convince to participate in their studies are untrained, this has led to an enormous amount of junk studies where they try to extrapolate the results to people who are not untrained.
    • nezi 8 hours ago
      This paper isn’t saying that it doesn’t matter what program you do, it’s saying that other variables, not directly related to the method of weight training, matter more. It also assumes that you can extrapolate data from one individual training each limb with a different program to if that individual performs either program on both limbs. Maybe there are carryover affects to the lower load limb that you get from training heavier with the higher load limb that you wouldn’t from training both at a lower intensity.
    • matwood 5 hours ago
      Yeah. When was powerlifting seriously I spent months with my deadlift stuck on 525 pounds. I would measure progress by how many times I could just get the weight off the floor, then how far off the floor, etc… The newbie gains were long gone.

      Also, it's more difficult to reach true failure with lower load, people tend to stop too early.
      • samiv 2 hours ago
        False,

        failing to lift is not the same as lifting until failure.

        Consider, if I load up the bench press to 200kg I won't get a single rep. If I try to rep it I'll fail but I'm not lifting until failure.

        If I load it up to smaller weight lets say 100kg and crank out rep after rep I'll get much closer to "lifting until failure."

        When I reach the end, the last rep is a rep I won't make. But I'm still not at a point where I can't do no more, just the weight is too big, so I must reduce the weight and go again. When I do this I get even closer to "lifting until failure".

        It's like integration, the smaller the infinitesimal the closer to the true value you get when you sum up (integrate) all the parts.

        • unaindz 35 minutes ago
          While technically true getting very close to failure is only useful if you don't need optimal results and lack the time to do more volume. The damage by going to failure will make high volumes maintained over time impossible.

          Ideally you would leave 1-2 possible reps. I think it's important to train to failure to know your body and learn to gauge your reps to failure but other than that and very little time per week to train it's eventually counterproductive.

          And if training with lower weights you tend to end very far from failure if just following a program without knowing what you are doing.

          • samiv 25 minutes ago
            Volume itself is meaningless. The only thing that matters is the intensity of the workout. In fact you want the maximum intensity with minimum volume to have less wear and tear and more recovery while maximizing the growth stimulus.

            First intensity. Then recovery. These two dictate the volume. If volume exceeds recovery injury and burnout will follow.

        Fixed that.

        As the comment you replied to noted, newbie gains are remarkably sensitive to any stimulation, and insensitive to the type of stimulation. Because going from zero to any resistance training is a massive stimulus increase, on a long-term under stimulated system.

        The study does confirm that. The data it produces is useful.

        What this study doesn't do, is help newbies (or anyone) choose the most effective practices to adopt. Because 10 weeks is way too short to identify best practices for any sustained program.

        Yeah, that's pretty much it. The counterarguments don't address what AstroBen noted.: newbies get high gains from any kind of stimulus. The paper has simply confirmed the common knowledge teached in universities.

        The problem is, after you are no longer a newbie you may train for years with very little progress, and that's when you need to start differenting stimulus, being strategic about it - otherwise you may stay stuck.

        And unfortunately the paper doesn't address or refute that, while it's coverage (or even the title of this hackernews) may suggest otherwise.

  • armcat 15 hours ago
    I thought it was already well understood/researched that it's not the weights that matter, but effectively taking your sets to muscular failure. While one might think "I can do 50 reps with low weights" there is practical aspects to this - you don't wand to spend hours at the gym, and doing heavy weights at 5-7 reps is sufficient as long as you are close or at muscular failure.
    • safety1st 11 hours ago
      There are a few issues with taking every set to failure, the most important being that it will substantially increase your risk of injury. It sounds great until you consider compounds like the deadlift that can ruin your back if your form is bad, and by definition, going to failure means your form will be imperfect at some point. There are lots of macho powerlifters out there with permanently ruined spines who will probably die earlier than they would have otherwise, due to mobility degradation.

      Particularly as you get older you become more injury prone and your recovery time slows down. This necessitates being cautious about how quickly you increase weight and how often you go to failure.

      The better goal to target is increasing volume, where volume is defined as Sets x Reps x Weight. The literature doesn't conclusively establish that any one of these is "more important" than the others for hypertrophy. The only real caveat when you follow this rule is that at a certain extreme of low weight / high reps (like 50 reps) you wouldn't actually be doing resistance training anymore, it'd be cardio.

      • Retric 10 hours ago
        2 reps in reserve is fine and far less painful, but you need to go to actual failure often enough to know where failure is on each set. I’m nerdy enough to suggest rolling a 20 sided die for each set, and on a 1 take it to failure it’s not that complicated and keeps your predictions honest.

        As I understand it taking a set near failure works reasonably anywhere between 5 to 30 reps, but 30 well controlled reps with good form * 3+ sets for each muscle group gets really boring.

        • nrhrjrjrjtntbt 9 hours ago
          Boring is subjective though. For some like me the ideal weight gives endorphins where as too much feels like cortisol. Too light is sort of nothing. So I aim for that "yeah I pushed something" feeling. Which isn't failure.
          • Retric 7 hours ago
            Let’s be realistic, everyone goes through periods when they just don’t want to work out.

            So optimal in terms of personal preference is defiantly worth considering alongside optimal in terms of results, but optimal in terms of returns on effort defiantly has a place at some point in our lives.

            • nrhrjrjrjtntbt 5 hours ago
              Yes guess it depends on your goals. Whether you are doing it for health, vanity, work or competitions will adjust the calculus.
            • matwood 5 hours ago
              This is key to recognize. Even when you don’t “feel” it you still go and do your program. But, when you do feel good, you go and push.
      • acoard 9 hours ago
        What about longer rest periods? For example if I wait 1hr between sets I can do full weight again without dropping down weights with a 2-5min break. In fact I can get multiple more sets in and significantly increase my total volume if I spread a workout over a day (which is easier with WFH). Any thoughts on this? Is there not enough muscle fatigue with this approach?
        • travisjungroth 8 hours ago
          Hard to stay warmed up that way. What you’re describing is how people tend to get big without the gym (lifting heavy things through the day) but they also tend be pretty active in between (think farm work).

          But as long as you’re not going so hard you risk injury, it might be great overall. Could be really good for your mental state.

      • samiv 2 hours ago
        Your point about the injury risk going up is valid. That being said going to failure and beyond is extremely effective way to train.

        As I mentioned in another comment a possibile way to mitigate the risks is to reduce the load and make the exercise harder and increase the time under load by slowing down the exercise.

        Also it's a good idea to swap from a higher risk exercise to a safer one to crank out the last reps. For example from squat to leg press.

      • siddboots 10 hours ago
        I think the total volume idea is more flawed than you realise. Pretty much everyone would be able to achieve greater volume, on any exercise, just by decreasing the weight, so your high rep caveat is covering up for quite a lot. This is true mathematically for an Epley style model for example.
        • matwood 5 hours ago
          > Pretty much everyone would be able to achieve greater volume, on any exercise

          I’m not sure this is true and it might be the opposite. Lactic acid will build up with light weight while trying to hit a volume number that will make it hard for people to finish.

          • Leherenn 4 hours ago
            Anecdotally, my gym had a "challenge" some times back where the goal was to achieve the max total volume in one set without pause.

            I tried various combos of weight* reps, and in the end the optimum was somewhere in the middle because no matter how light the weight there was a limit for me at about ~150 reps.

            In my case, the curve would be: total volume increases quickly initially at you go from max weight/1 rep to something like 20/30 reps, then something of a plateau as things equalise, then it goes down again as you reach the max reps threshold.

            • matwood 4 hours ago
              Great point. Personally I find lactic acid build up way more limiting for me than muscle fatigue. It's why I gravitated towards power lifting.
    • kace91 14 hours ago
      >While one might think "I can do 50 reps with low weights"

      The caveat is that you need anaerobic training. Low enough weight and it’s cardio, you don’t get giant legs by walking to failure for example.

          There's a difference between the guys who cycle Tour de France vs the ones who go around in the velodrome.

          The former group is endurance athletes with skinny legs and the latter group is more focused on maximum power. Similar to marathon runners vs sprinters.

          The pro velodrome cyclists do tremendous leg training programs specifically to develop the muscles. It's not the cycling that builds that muscle.

          Yeah uphill cycling or sprints probably go anaerobic at times, you can tell because you need to stop from the muscle burning/refusing to move, rather than going out of breath or general tiredness.

        Has anyone really ever walked to failure on a regular basis? I typically have to stop because of blisters not muscle failure. (The furthest I've done is 12 miles with +10% weight.)
        • exq 10 hours ago
          I backpack often (usually 8-13% bodyweight in my pack) and during long summer days I can comfortably push well into the 30 mile per day range if there isn't too much vert to slow my pace down. My feet get sore, brain gets tired, and I run out of daylight well before any sort of muscle failure in my legs. If you aren't used to walking from sunrise to sunset doing so would build muscle, but your time would be better spent on a progressive overload leg routine in a gym.

            Yup, I have never gone that far (but my summer hiking is entirely at high elevation with lots of climb) but I have never found anything like a failure point--I wear out because of time (not even daylight--I've made navigation errors that left me out there well past sunset), not muscle failure.

      The weight does matter. You will never get bigger if you don't add weight to the bar, and you will never get bigger if you only train at 1% of your 1 rep max, no matter the number of reps. Producing a training stimulus requires placing the muscle under sufficient tension (enough weight) enough times to be at or near failure.
    • sedivy94 8 hours ago
      Novelty of stimulus is a huge factor, especially as training continues over years. Failure from a set of 20 is very different than failure from a set of 5, and bodybuilders will periodize their training to cycle through the different flavors of stimulus. I think a big contributor might be neuromuscular adaptation. Cycling through those different intensities over training periods measured in months will make this apparent anecdotally.

    • calmbonsai 8 hours ago
      There's also the risk of injury.

      At very low reps and high weight, particularly for highly coordinated motions (squats, dips, pull-ups, Pulver press back-extensions), there's a much higher chance for injury due to insufficient support at one or more positions within the entire range of concentric and eccentric efforts by all activated muscles. We all have, at the very least, minor intrinsic asymmetries that need explicit addressing.

      There's also intra-set recovery. Roughly (very roughly) speaking, your endo-neuro-muscular system "adapts best" where there is a refractory period for a reset-to-quiescence between exertions.

      There is real truth to "muscle memory" and the exclusive way to achieve that (and avoid injury) is through a sufficient amount of well-formed repetitions. The only way to achieve those repetitions is by using a resistance that's sufficiently low.

      • vjerancrnjak 7 hours ago
        Asymmetry is normal and you cannot address it (outside of repeatability of movement, aiming for no form degradation during high load).

        As long as your movement does not degrade horribly, asymmetry is fine.

        Even before strength training, your one arm is dominant, more precise. But this has an effect on your leg as well.

        Doing unilateral work will never change that asymmetry. As you get stronger, due to drastically different activations of the nervous system between the sides, you will get slightly different adaptations.

        Looking at powerlifters, most of them have visibly different sizes of hip, leg musculature between sides. They even have drastic flexibility differences where one hip goes deeper, or the musculature makes the barbell sit skewed on the back.

      • samiv 2 hours ago
        If you were a newbie just getting started.. the ligaments and tendons take much longer to strengthen than the muscle. So the muscles getting stronger will outpace the connective tissue.

        Second potential issue is too much training vrt recovery.

        A good way to add safety margin when training to failure is to reduce the weights and slow down the exercise and increase the time under load.

        For example bench press, do 5s down (eccentric), 5s pause (isometric) and then (optionally) 5s press (concentric). Your weights will go way down because this exercise will be so hard. But the stress on the joints and ligaments will be reduced.

        That’s a Pl/Oly mindset rather than a BB/hypertrophy mindset. Totally valid advice in the right context.

        Long story short, failed reps get much more risky and problematic as the weight you’re lifting approaches your 1RM.

        • Moto7451 11 hours ago
          Exactly this. When I was in my best shape my deadlift and squat were in/on the way to 2.5-3x my body weight. You don’t want to fail that without a lot of help and safeties.

          Note for the uninitiated: That figure is not even impressive or competitive with competition lifters. This is just “guy who put in the time and work” numbers.

      • NoLinkToMe 9 hours ago
        It holds true, but with some caveats.

        Generally training to failure is completely fine for say a set of tricep extensions. Generally safe.

        However, training to failure on compound lifts like a deadlift or benchpress, or involving sensitive muscles like a shoulder press, isn't.

        Technique generally suffers at the point of failure. Making a habit of doing thousands of repetitions in the next decade at the point where technique fails, on an exercise that can mess up your back permanently, or your shoulders, is bad advice.

        For these exercises it's better to stop 2 reps short of failure. This is more safe. Also it requires moderate recovery getting you back in the gym quicker, meaning you can compound more incremental improvements in a given training period (say 5 years).

        Even then, some still cautiously go to failure to keep an understanding of what their failure point really is. You could go for a PR once or twice a month for example and go to failure, with a proper warmup, spotter etc. But purely for hypertrophy there's not really a point, this is more for strength training.

        Generally people that say they train to failure mean 2 reps in reserve. Training to absolute failure on all muscles is very rare and generally advised against.

        • calmbonsai 8 hours ago
          True. Generally, the more isolated the exercise and the smaller the muscle the "safer" it is to train-to-failure at a higher duty-cycle.

          Put another way, you can do crunches to failure every single day, but you'll want to keep some reps in the tank for squats and you'll want to plan on at least 12-24 hours of recovery between squat sessions.

      • teecha 13 hours ago
        not an expert, 2 years of serious lifting, but this is probably a good adage for the average person from my current understanding

        training to failure puts you at higher risk of injury and there are diminishing returns as you approach your 1 rep max and/or failure

        hypertrophy can happen with more reps or more weight

        strength gains are usually just focused on progressive overload

        though, of course, hypertrophy will happen either way and contributes to increased strength, but this seems to be further confirmation that you can gain muscle size either way

      • nzeid 13 hours ago
        It's definitely way more nuanced than that. You have to approach exhaustion to get the body to eventually build strength. But you need to carefully time your rests/deloads and handle plateaus with more volume.

      I would argue both categories of the study are about low reps. I don't see how the body would tell the difference between 12 and 25 reps. If you said between 5 and 500, like it has to meaningfully take much longer, otherwise why would doing something so similar have any meaningful difference?

      The way I think about it is that nature mostly reacts to order of magnitude changes. 12 to 25 is the same thing.

          To be clear, the implication is that 12 and 25 have different weights so they tire you the same amount. Do you think it would be a very strongly felt difference in that situation? What would the difference feel like?

            Yes, this is why classic body builders like high reps because they get the pump but you can get the same growth (and there’s lots of research saying more) with training to failure with low reps and high weight but it doesn’t give you the pump.
        • vasco 5 hours ago

    I just do light weight nowadays with my strength training. It’s easier mentally. Rather than push myself to go higher on bench, squat, and deadlift, I stick to 1 plate for bench and squat and 2 plates for deadlift. Every single time. Instead of increasing load, I increase rep amount and focus on my form. Honestly, I still find myself sore after most workouts and the simplicity is nice. I’m 25 for reference.

      You won't see any progress if you won't push yourself. It shapes your mentality, and running away from work is what will keep you at the same place. Soreness is not a sign of progression most of the time. Bump up the weights, don't run away.

    If I read this correctly the gist is that it does not matter if you use heavy weights with few reps (common body builder wisdom) or lighter weights with more reps. As long as you always exercise to complete muscle fatigue you'll get the maximum for your genetics (which itself varies a lot).
    • bob1029 13 hours ago
      There's no way this works in practice. A lot of heavy lifting (maximums) is about neurology and mind-body training. You cannot develop the ability to deadlift 405lbs by spending 2 hours using a cable crossover machine every day. Picking up something that weighs 2x more than you do requires your brain to send an extremely strong, synchronized signal. This is something that takes a lot of practice to develop. You have to consistently push your maximum voluntary effort in order to expand this capacity.

            Body mechanics, leverage, and neuro-muscular connection definitely come into play. I could deadlift 430lbs for reps at my peak, and I while I was no string bean, I also didn't look all that muscular compared to the other lifters at my gym. I have ridiculously long arms relative to my height and relatively shorter legs, which gives me an advantage for deadlift. I had monstrous-looking guys watch me lift and then ask me what stack I was on. They didn't believe me when I said I was natural.

        There is a minimum weight you must use to create a training stimulus, but yes, you can increase your 1RM with higher-rep sets (again, to a limit, they can't be sets of 100, the weight is too light).

        To increase your 1RM at the most optimal pace, yes you need to specifically train the movement so that you can benefit from improved technique and neurological adaptation. But if I do tricep, pec, and front delt isolation exercises at higher reps, to failure, and see significant hypertrophy in these muscles, my bench press will be stronger, other things constant.

      > heavy weights with few reps (common body builder wisdom)

      It is strength training (not body builder) wisdom to use heavy weights with few reps. Hypertrophy (i.e. body builder) programmes usually call for 8-12 reps, which implies relatively low weights.

      • NooneAtAll3 13 hours ago
        is "8-12" not "few" for you?
        • rorytbyrne 13 hours ago
          Relatively speaking, no. Strength training (as opposed to hypertrophy) calls for fewer reps, around 5 per set.

          Many people advise spending about a year doing more sets of fewer (~5) reps to build strength, and then switch to fewer sets of more reps (8-12) when you want to build muscle mass.

          Point being, the idea of doing lighter weights until failure is already kind of there in body building wisdom.

        The reason no one has found a better way is because hypertrophy is because it’s well understood and there’s no “better” solution. mTOR is the primary hormone pathway.thy increase the adaptation ceiling by increasing RBC, reducing protein breakdown, etc. Thereby reducing rest needed, so mTOR is heavily unregulated.

        This is one of the view places where “if we could we would” is the correct answer. There is so much money in the space of anabolic cheating, the clandestine scientists would’ve already developed it.

      • d-us-vb 14 hours ago
        This. Muscles can be optimized for volume/endurance or power, or some balance between them. Taking legs as an example: Powerlifters obviously go for pure power, whereas runners need a bit of power but mostly endurance, whereas cyclists need more power than runners but more endurance than powerlifters.

        All of these benefit from weight training, but depending on the sport, the programming will be very different.

        • allan_s 13 hours ago
          I think I know where they're coming from as I used to have a similar wrong model. I thought strength = more muscle cells and endurance = just better heart/lungs to deliver oxygen and clear waste like CO2 and lactic acid.

          Turns out muscle fibers mostly grow bigger rather than more numerous, and there are different fiber types (slow-twitch vs fast-twitch) that adapt based on how you train. So for the same muscle, an Ironman runner and a guy doing heavy low-rep squats will develop different fiber characteristics: you can't fully max out both.

          I'm simplifying, but learning this changed a lot about how I understand exercise at the biological level.

        • zemvpferreira 2 hours ago
          Since I'm nitpicking let me point out that powerlifters train for strength. Power is an altogether different (though related to a degree) muscular/neurological characteristic. Power would be more closely related to olympic weightlifters or sprinters/shot-putters etc. Endurance could also be broken into alactic/lactic/aerobic capacity which makes a huge difference at the margins where athletic excellence is made.

    Age: 22+-3 AND with that weight to ffbm ratio not only untrained, but at least slightly (I’m being generous here) overweight.

    With these pre-requisites it almost doesn’t matter what kind of physical activity one does- the muscles will grow anyway. It’s when you are older and/or accustomed to some kind of physical training, that you really noticeably benefit from resistance training.

    And still, that ‘almost’ part does a lot of the heavy lifting here. I don’t believe it’s really possible for a couch potato without any experience to correctly assess their 1RM. People with no experience with pain and effort typically can’t push themselves hard enough, so the entire exercise turns to a half-cardio anyway.

    And gauging 1 rep max in a bicep curl is especially difficult (saying nothing of a risk of injury).

    I understand the complexity and difficulty of researching the subject, but this entire article is no good and is hardly applicable to most of the population IMO

Have you considered how many people live in a way you would never consider close to acceptable?

      Because your points make sense but it feels like you are arguing against a bit of a strawman, or arguing for a mostly ideal situation rather than current reality?

      For overweight and understrength people, is it not very valuable to know that they don't need the extra steps of resistance training to see real improvement in strength and fitness?

      • DiskoHexyl 4 hours ago
        This doesn’t look like a particularly charitable interpretation of my comment, although my interpretation of the article isn’t either, so it’s only fair.

        And no, I am not looking for a personal fitness advice in scientific research anymore (too late for that), but am rather trying to see its applicability to others, as per my understanding of those others around me.

        Most people in the developed world aren’t 22-year old males. A significant part of the population is comprised of the elderly or middle-aged, a lot of those people have pre-existing injuries due to under- (too sedentary) and over-use (blue collar work, youth sports). Approaching physical fitness in those groups has its its own set of requirements and limitations, and I believe that in many cases resistance training is a more safe and efficient choice.

        Not saying that the youth and children are unimportant, but typically they are already well covered by the organized sports and pt classes in schools and universities, unlike the adults.

        My opinion is that the study is both badly designed (likely in a way to make it easier to implement) and is not applicable to the majority of the population.

    • vidarh 4 hours ago
      > I understand the complexity and difficulty of researching the subject, but this entire article is no good and is hardly applicable to most of the population IMO

      Most of the population is untrained, and in many countries a majority is overweight.

      I don't think your concern about "correctly assessing their 1RM" matters either - if anything that means the loads are even lower relative to actual 1RM, and their subjects were still getting results.

      It may not tell us much about outcomes at the top end, but more knowledge of what advice to give "most people" is important, and if they can get good results at low percentages of 1RM, it seems a lot more likely you'll get people to try.

      • DiskoHexyl 3 hours ago
        That is exactly the issue with incorrectly gauging 1rm- if it’s too low, than the supposed ‘resistance’ training with 70-80% of 1rm isn’t actually that.

        Is it fair to compare A to B, when the A in question isn’t exactly an A, but rather something closer to B?

        • vidarh 41 minutes ago
          It is fairly irrelevant when you're dealing with a group of people who are all using the same means of determining their 1RM.

          The point isn't the precise effect on a given percentage of 1RM, but the relative difference between groups.

    • vjerancrnjak 4 hours ago
      They have to start video recording the workouts. Even veterans in this academic field sometimes design workouts that just can’t be done to failure if you’re actually going to failure over 6-12 weeks.

      Even 1 workout sometimes has so many sets prescribed where I cant imagine all of them were actual failure

    • sigmoid10 4 hours ago
      >It’s when you are older and/or accustomed to some kind of physical training, that you really noticeably benefit from resistance training.

      Do you have any sources for that? I'm asking because that is a bold statement given the (almost non-) existing literature on pro athlete hypertophy. Especially since athletes in almost every sport don't even care about hypertrophy - unless you talk about pro bodybuilding. And there you have tons of pharmacological interventions, so it's not really easy to paint a picture either. I don't know a single good study performed on a significant set of tested natural bodybuilders regarding hypertrophy.

      Studies like this are also aimed at couch potatoes, because that is the normal population, so the results will be applicable to most people, which in turn is important when you want to get funding for your research. In that sense it also doesn't matter that these people will not have reached their full neuromuscular connection compared to actual weightlifters, because most people haven't either. So the results are still relevant. Usually when scientists sell this kind of research to grant departments, they try to provide a benefit to geriatric or otherwise medically impaired people, so that existing treatments may be improved. Studying muscle building itself just for the sake of it in gymbros is not a good strategy unless you want to spend your own money. And this stuff quickly gets very expensive if you want to do it right.

    As a natty bodybuilder for over 30 years for anyone aspiring towards fitness and starting at the gym my most important advice is

    "Put the phone away and bust some ass"

    I see way too many people (the great majority) completely sabotage their training by putting the weights down when it starts to get hard and get on their phone.

    When the weights get hard is when the real set begins. If you don't do the hard reps you deny yourself the stimulus required for adapting to overcome the stress, I.e the growth.

    • MarcelOlsz 3 hours ago
      This is why having a buddy/spotter is so important. On every lift my friend spotted me an extra 3-4 reps that I would not be able to do if I went just myself and kept going until the last rep was 95% him and 5% me. First guy to automate spotting is an instant billionaire.
      • samiv 3 hours ago
        Depending on the exercise you can also do this without a spotter.

        Either do cheat reps and focus on the negative (works with small exercise such as bicep curls) or drop set or super set.

        My personal fav is the cheat and negative and I do it a lot for example in cable pulldown. Use a bit of bodyweight to pull it down and then 5s negative.

    Even if true, high rep is impractical, otherwise we'd see people doing body weight exercises only reach high levels of bodybuilding.

    You cannot be strong without being big and you cannot be big without being strong.

    Of course there are levels to this, variations within “weight classes”… but in general this holds true.

    Also consistency trumps any program.

    • samiv 2 hours ago
      False.

      Strength as measured by mostly powerlifting is impacted by a huge factor by the body mechanics, i.e the length of the various body parts, secondarily by tendon attachments and then finally by variations in tissues

      • wallaBBB 2 hours ago
        Thats the variation within the classes. And there will always be outliers, but even if you look at bodybuilders in 100+ kg, they are not what you’d call weak even if they don’t optimize for strength.
        • samiv 2 hours ago
          Relative to their size a lot of them are weak.

          Again despite size it's the body mechanics that determine most the physical lifting capability of any individual in any particular lift.

  • padjo 6 hours ago
    The quality of evidence in exercise training is generally pretty terrible. 10 week study with untrained college students tells you very little about what happens over a lifetime of lifting. Personally I’ve found that switching rep range on an exercise is a great way to break through plateaus.

    Ultimately you’re engaged in an n=1 study and general advice is of limited use. You need to learn what tools are available, how your body reacts to different stimuli, what keeps you consistent etc. Everything is context dependent, trying to find some universally “best” way is a wild goose chase.

  • leonflexo 7 hours ago
    I thought hypertrophic focused routines were their own subset. Starting with a high rep, like 20, decreasing something like 2/week while increasing the weight. You technically can increase load, but in my experience it isn't strictly necessary. 10-12 weeks down to 1-2 reps then 3-4 off to reset. This isn't a strength routine, simply for size relative to lift.
  • n2y 4 hours ago
    The study assigned different training regimes to different limbs of the same person. If you think their measured effects do not reflect your own experience, I'd be interested in your fitness status and your result when you do the same. Otherwise it sounds a little like you are disputing the study because it showed something different to your belief.

    I know it's practically de rigeur to jump into the comments and immediately complain about methodology for any study that makes it to the front page, and I want to emphasize I don't distrust their findings, but I would like to see an equivalent study go out longer than 10 weeks. When I've been taking weightlifting seriously I feel like I don't even start to notice hypertrophy until 8-10 weeks. I feel like 6 months is the actual period where results would matter, to me, but I assume "subject compliance" is pretty difficult to get for such a timeframe, if you're really watching dietary intake and ensuring subjects go to failure (which, to its credit, this study did).

        I’m not at all a biology expert, but if the squat is actually pushing you somewhat close to your limit (it’s not super easy), you’ll definitely get stronger. Case in point: isometric exercises. Also: folks who do planks for a few weeks/months.
  • bethekidyouwant 14 hours ago
    The group that did lower reps with higher weight, had the better one rep max at the end of the study, but they didn’t measure if the higher rep group had greater endurance. Which seems a bit odd, considering their conclusion is both groups grew the same amount of muscle which fine but if the muscle is adapted for something different in each group, you would want to capture that.

    I am afraid of trying to lift to failure. never once been in a gym, or trained for anything except marksmanship, but have alwayse been physical, with a lot of what I call "dirty lifts" in the course of getting things done,pushing 60 now. I do notice that after a stretch of realy hard work, and taking a day or two to rest and EAT, I will bulk, but nothing is by the numbers, except the day I took over the old blacksmith shop and we took the gentlmans anvil down, and lifted mine up, each of us grabing one end with one hand, my anvil weighs 460lbs, he was in his 80's and I was in my late 20's. I muscle everything around, steel, wood, round bales,but follow the philosophy of "just because you can, dosn't mean you should" which I believe is especialy true for realy big guys, because while you can build huge muscle, your cartlige and coligen is no better than an size small office guy with that florecent tan, where I have seen in the same frame, a big guy pushing 40, not moving good anymore, and foccused dweeb gettin his lunch zipps right through, doesn't even see the hulk. my point, if I have one, is that nothing counts, unless you can style it
  • henning 10 hours ago
    Yep, lots of different ways to get jacked. That means if you couldn't care less about strength, you can do pretty much any decent exercise that targets the muscle(s) you want to grow in a very wide rep range. Most people want a combination of both size and strength, so you can just do some sets of 5-10 if you aren't already. If you want to have a strong deadlift or squat or whatever, you should train that movement. Not as complicated as fitness social media people want to make it seem: train for what you want.
    • esperent 7 hours ago
      I don't think this is true. I've been following a fairly standard progression on several of the standard exercises over the last year and half. I've seen steady progression on leg press, which is a strongly stabilized and isolated exercise. I saw the same rate of initial progression on squats but then it dropped off and I haven't really seen any progression for six months.

      The issue is stability. I have to provide the stability for squats. The machine gives me stability for leg press. I won't get the stability I need for further progression, at least not at an optimal rate, just from squatting. I need to do complementary exercises.

      When training for muscle size atleast, but not strength. Presumably there are increased injury risks overall when lifting heavy (based on a brief search).
    • teecha 13 hours ago
      fairly new to lifting myself (2+ years taking it seriously) but this thing seems to jive with what I've read across different areas

      bodybuilders can build muscle size with high reps and lower weight or lower reps and high weight as long as they do it close to failure with only a few reps in reserve (rir)

      powerlifters, or those focusing on strength, usually go for high weight and lower reps because they might be training for a competition that focuses on 1 rep max and/or the body can really only handle so many reps when pushing it at 80-90% of 1 rep max

      neither is inherently better but a matter of what goals you have in mind, plus, hypertrophy contributes to overall strength, too

        If it's not painfull you are not exerting enough effort at least that's the case in the gym. People who are refreshed and more energetic after going to the gym are the same people who won't improve beyond intermediate levels. The ones who let go of the any set at the first feelings of unease and never take a set close to failure.

        It's actually fascinating how an ancient proverb could line up with modern science so perfectly.

      This is really terrible advice that just discourages people.

      You absolutely can get significant improvements without (much) pain. DOMS during the initial stages is going to be the most uncomfortable part. Once you're past it, you don't need to push yourself to a breaking point, just to the point of mild exhaustion.

      This will provide you enough resistance to gain muscle mass and improve the bone density to healthy levels.
