Just got done working out and I literally just injured my knee, coincidence? I think not. Exercise is trying to silence me. SEE NOTE(S) BELOW Note 1: A few people have already mentioned steroids as a possible reason why, and I think this critique of the analysis is great, except there's one issue with it that I would have you consider. Yes, steroids is a possibility and makes tremendous sense to be in people who lift a lot of weights. However, for the data to consistently shoot up like that, it would mean that steroid user would have to make up the majority of the data set, so the question you have to ask yourself is "do I believe a majority (or close to a majority) of people who lift a lot are steroid users?". My naive guess is 'no', but what might make sense is that more men use exogenous testosterone (TRT), so could this skew the data somehow? Maybe, but we'd need to look at specific longevity data on TRT users (maybe something I can look into for you?). Note 2: "Is there a chance that the factor for the increase in overall mortality, cancer and cardiovascular disease and the increase in resistance training per week is a matter of diet? Since people that lift for longer times during the week usually take it more seriously and therefore watch their protein intake. Since eating high amounts of meat, eggs and possibly dairy (for a more efficient intake of protein g/100g) is associated with all of these increases in risk of mortality, cancer etc? Since that would definitely factor into the development of these diseases (knowing that processed meat is a known carcinogen as well as high amounts of meat in a diet, not to mention the cholesterol amounts associated with these amounts of food). I could be totally off but that's my best guess." - a point by @leonardodicapriojojo to consider (thank you for sharing!) Great points, guys!

I think the obvious question is how the "minutes" of exercise were calculated. If I go to the gym for 90 minutes, I am actually only lifting for about 15-20 minutes (say 30 sets in total, with each set being about 30-40 secs). That's the critical factor. Of course there are people who spend 4 hrs in the gym and only lift for 10 mins. 😂

[@lightbringer589]

My thoughts exactly!

[@Physionic]

An excellent question - they did not define it, so I'm not sure, but I would GUESS that it's estimated time exercising, not rest time. I'm sure there's some inaccuracy there.

Good question. If we do not count rest periods and only the actual lifting time, 40 minutes seems more then enough. Considering that one good hard set on average should be 40 seconds. 40 minutes of lifting is ~53 sets which is perfect for 5 muscle groups.

One possible confounding variable: Steroid abuse. Lower lifting durations may be the norm for demographics primarily looking to improve their baseline health while those with extensive training sessions may be more likely to do it to boost self-confidence and appearance, and have to deal with the temptations to enhance their physique that many of us have been exposed to along our weight lifting journeys. - I think follow up studies are needed where bloodwork to detect unusually high androgen levels (and signs of other performance-enhancing drugs) are also in effect before we draw any significant conclusions regarding possible adverse effects to longevity from extensive exercise!

⁠​⁠@@AntiTheismForevernah, that has been disproven over and over, for years (that’s why you don’t see a bunch of carnivore centenarians walking around - good for short-term gains, bad for longevity, just a fact supported by solid data). The increased protein requirement for older age is not that drastic either, to the order of 15-20% over minimum requirements, which pretty much brings it up to the level of a standard western diet. Finally, there is very little conclusive evidence to show tangible benefits from grass-fed meats sadly (other than the obvious ethical reasons). All-in-all, studies keep pointing towards the same boring conclusion: just eat a balanced diet, use moderation, and don’t fall for the latest extreme fads.

I am 61 years old. I have been active in martial arts and resistance training most of my life. Started martial arts at 10 years old and still do it 4 times a week, resistance training started in my 20's. I move like a much younger man compared to my contemporaries and frequently better than those 25 years younger than me (remember to work those type 2 muscle fibers). If exercise didn't add 1 day to my life being fit and mobile alone would still make it worth it. Exercise creates a lot of oxidative stress in the body. When combined with a poor diet I can see where some would not benefit as much from exercise. Take your anti-oxidants. also, 60 minutes in the gym is not 60 minutes exercising. If I am focused on the task, reduce distractions I can be in and out in 45 minutes with 20-30 minutes of actual reps.

This data does not surprise me at all. I am 60. Been lifting for 40 years. Used to do 2-3 hours a day 5-6 days a week. That pace, for years, left me with constant injuries, depression, frequent colds and little in the way of gains in size/strength. I learned the hard way that too much (or little) of anything is detrimental to health. All must be in balance. Intense exercise is a stress on the body and initiates a lengthy cycle of recovery and over compensation that is "healthy". But too much exercise, too frequently interferes with this cycle and leads to a decrease in "health". Short, brief, intense and infrequent lifting has demonstrated the best gains in muscle size/strength and overall "health" over the last 20+ years. Arthur Jones/Mike Mentzer..... were on the right track. More is not better.

Yes, ckd is increased with people who have a body type/dna that tears down muscle more easily than others. It is also an indication that your cells are getting trashed more frequently. In my case it was exposures to Gulf War toxins of oil well fire smoke, insecticides, volatile organic compounds from freshly opened tents or new vehicle prep, and many too close together immunizations. I'm still alive at 67 with years of higher than normal ckd, so you are probably fine. It always goes back to trust your body and gut more than tests and doctors. 😊

[@mjwrather]

Trying to compare my resistance training time to studies is tricky because, unlike cardio, there's so much downtime when lifting. It makes me think that "minutes per week" is a pretty poor metric to measure against because it doesn't capture the amount of work being done. It's so easy to take twice as long in between sets and to have that not captured in the data.

[@pietjonker2480]

I had the same thought

[@kevinharris8535]

That was my first thought as well. My split is strength train then next time it is endurance/growth. So my strength train day is about 3 minutes rest between sets and my endurance/growth is 90 seconds rest with lower weight and higher reps. Strength day is much longer than endurance/growth day but I am doing much less reps although it is higher weight. Very hard to put this to practice.

[@Kailokel]

Agreed. I would love to see something like working sets per week (with greater emphasis given to multi-joint exercises over single-joint exercises) used as the independent variable.

[@DIYDSP]

All true. Plus it's self-reported as opposed to say a blood test so everyone will measure it differently.

[@dlg5485]

This doesn't surprise me at all. Over-training has always been a thing. I've seen it impact people I know in very negative ways. In my opinion, balance is the key to good health and longevity. I am 54 and I do resistance exercise for just 1 hour 3x per week (including periods of rest) and this seems to be a sweet spot for me. Obviously, more of a good thing is not always better and this applies to exercise, as well as most good things in life. I look and feel great and I'm not wasting time working out that don't provide any benefit, and may actually cause harm.

[@nimblegoat]

I 'm 59 and starting out at gym - 3 times a week - with some small stuff at home , or some quick pullups in park ,. I 'm just seeing what's possible . I think some of those doing huge progressive overload multiple types per week - are decreasing some benefits , extra muscle , extra weight , extra resources in body to maintain it all - add in possible poor diet . My aim is to get to a muscle up and a pistol squat - both really need leaner body , Plus get body fat done to say 14/15 % - I want a bit of body fat for it's protective benefits and I know when I set off travelling the world again , I will lose weight , so don't want to be at 10% to 12% . I think this needs more nuance - not enough rest time , stress elsewhere in life , carrying too much muscle , not eating right , personality OCD training etc , drug/supplements etc . Listen to your body - probably in 6 months will go into maintenance phase

[@TA152H01]

I'm not sure why you'd be confused. It does make sense to me. It's called overtraining. When I was young, I would work out six days a week, and I did really heavy weight. I was sick all the time though, which was bizarre because I had a 30 inch waist and 50+ in chest. As it turns out, your ability to do work goes up faster than your ability to recover from it, and you have to reduce your workout. Or make no progress, and apparently have health problems. I read something from Mike Mentzer, called Heavy Duty, and reduced working out to three days a week. I built muscle so fast, people thought I was juicing, but I wasn't. I finally let my body recover, and I felt much better and was much healthier. More isn't always better. I still work out three days a week. I do one "real" set per exercise, because you only need one set to stimulate muscle growth. That one set is extremely intense, so much so people always ask me why I do it, or if I'm OK. If you do it right, one set is enough. But, you have to really do it. I'm 60 now, and still do pretty much the same weight. I'm convinced it works, and I'm convinced overtraining is worse than undertraining, having wasted years on that path.

[@leononymous2562]

This is the quality content we are looking for and why I subscribed! Thank you! I think many underestimate recovery. Even some bodybuilders say they only train a specific muscle group maximum once every two weeks. Also, in the Huberman Lab Podcast with AthleanX, Jeff points out the individually different times for recovery. Some might need two days, others two weeks. Lastly, Bryan Johnson from Blueprint comes to my mind. Though there are many things one can critique about him and his techniques, he states he would love to train more but does not for recovery reasons (healthspan and lifespan goals) and I think he is very correct about that. The body simply needs time to recover and can not „repair“ properly, if there is too much „damage". But yes, we need much more studies on this. Super interesting video!

[@user-fl5lr1nm5v]

There is also a confounder in the curves you presented. The inflection point may indicate those people who train excessively. These individuals often, not always, take ‘supplements’ (and not the safe variety either). This will skew the curves in the way you showed. It is similar to the ‘weight’ graphs. People with low weight have higher increased risk of all cause mortality because they often have low weight for a reason (chronic disease, malnutrition etc.). People with high weight also have increased risk of ACM because disease like diabetes, heart disease etc.. take them out.

My grandpa exercised his entire life every day but in about the last year of his life he stopped. I kinda think he did it on purpose so that his health would decline further. He'd already had a stroke but he was still ambulatory and he could talk. His biggest things were that he couldn't control his right hand and he would say a lot "I can't talk" like he couldn't say what he wanted to but on the outside when you listened to him he sounded fine. I think he stopped exercising though because his wife, my grandma had already passed away and many of his peers and friends had passed away

It does seem strange to me that all of the men that I know personally who spend hours in the gym also have sports bikes, guns, and eat lots of meat.

150 minutes of actual working out in the gym (as in time actually lifting in your sets) is really alot even if its for a whole week. These days if you are spending 2 hours in the gym, you are literally scrolling Instagram on the bench for at least half the time resting between sets.

[@An1MuS]

Indeed. For me it wasn't clear, maybe I missed it, whether the time here includes resting or it's just pure exercise time. If it's pure, then even 60 min of strength training per week is quite a bit. If a set takes let's say 1min to perform (often less), then that would be already 60 sets.

Mike Mentzer used to say that the body didn't have enough time to recover if you increased the training frequency too much. Pair that with all of the body's subsistems being stressed out beyond belief from too much training, and I think it's almost common sense that the body ends up more prone to diseases as a result. We aren't meant to be working as slaves or beasts of burden as, our bodies only get stronger when we rest. I've talked to people who consistently feel sick from going to the gym 5 days a week, and I've heard people say that doing exercise can reduce your inmuno-defense system. So it stands to reason that overworking your body just has a negative effect overall on your health, too. I think, if anything, this study just proves that theory all the more. If you train more than 2 hours a week doing heavy weights you're stressing your system more than may be necessary to grow muscle, and you can definitely get significant results with as little as 30 to 40 minutes a week if you actually know what you're doing. Just use your time elsewhere and be more productive.

[@neferiusnexus]

this actually correlates well with 20 minutes being the maximum for muscle gain per day and needing three rest days per week... 4 days of heavy lifting would add up to 80 minutes of weekly exercise, which is about where the charts seem to start exponentially climbing back up in terms of negative outcome.

Every morning: Alternating between "karate" style side kick holds and yoga-style "toes touching the floor in a lying legs-over-head" stretch (5-7mins). 4-day Main Exercises Cycle Day 1) Legs - body weight incl hamstrings & calves. Single-legged squats get brutal fast! Day 2) Chest, shoulders, triceps - with weighted backpack, bands. Includes wall handstand - current max time 1 min 2 secs. Day 3) HIIT - hill sprints. The recovery period is while walking back down the hill (very lucky to have a perfect steepish hill nearby). Day 4) Back & biceps. Currently back up to around 12 pullups, 8 super-wide at the end Day 5) Either a rest day or start back at Day 1. This week I started introducing Zone 2 for 30 mins in the evening but just got a couple of sessions in. It's pretty much the last piece of the physical puzzle IMHO. Very happy with the above.

[@flanker909]

This is true everywhere, more is not always better. There is a "sweet spot" in everything in life. My humble take on resistance training when overdone is not allowing the body to repair the damage in cells caused by a training session so damage accumulates which leads to an unhealthy response from the body, some would even use drugs to speed up recovery and boost energy levels artificially. This is when good turns into bad. Exercising should always remain a mean to stimulate the biological functions of the body with measured and reasonable stress AND allowing the system to repair and recover. Staying away from PEDs is also crucial to never lose the natural feedback that the body always tries to send to the brain, those are clear signals on how to manage progress while staying in the healthy ballpark.

[@leonardodicapriojojo]

Is there a chance that the factor for the increase in overall mortality, cancer and cardiovascular disease and the increase in resistance training per week is a matter of diet? Since people that lift for longer times during the week usually take it more seriously and therefore watch their protein intake. Since eating high amounts of meat, eggs and possibly dairy (for a more efficient intake of protein g/100g) is associated with all of these increases in risk of mortality, cancer etc? Since that would definitely factor into the development of these diseases (knowing that processed meat is a known carcinogen as well as high amounts of meat in a diet, not to mention the cholesterol amounts associated with these amounts of food). I could be totally off but that's my best guess.

[@Physionic]

An excellent suggestion., leonardo. I think that's incredibly plausible. In that situation, doing a subgroup analysis to separate out protein intake and then another one separating out meat intake would have been stellar to find out. Or, adjustments for a number of covariates (like the ones you mentioned) to see if the association remains or shifts... Going to pin your point.

Interesting study- Peter Attia did a podcast episode in which he and someone discussed a distance runner that was so addicted to the runner's high that he actually shortened his lifespan by over stressing his cardiovascular system. I'm similar to you, Physionic, in that I really push myself in the gym. Until recently, didn't think that this was harmful for my body in any way. However, my thinking was the opposite of your hypothesis when it comes to exercise effects and age. I was listening to Dr. Paul Saladino talk to Georgi Dinkov (a Ray Pete disciple) in another podcast. In that podcast, Ray Pete suggested that the human body dealt better with the stress of exercise in youth and that the endocrine benefits that enhanced health were also experienced in young people. His suggestion was to remain physically active as one aged but that one should not push oneself in the gym as much by lifting heavy weights. That made me interested in building as much muscle now before it become more difficult and before my body couldn't handle the stress as easily. Doctors like Peter Attia do like to toss around metrics around the relationship between strength and aging (grip strength has a positive correlation with mortality?). I'm not sure what research is supporting these metrics but they imply that naturally derived muscle is almost always beneficial for longevity. A central factor that may unite many correlates with longevity maybe the capacity to recover from stress/capacity for anti fragility and adaptation. Again I will cite Attia again but this time with the discussion with the researcher Eileen White peterattiamd.com/eileenwhite/. Eileen mentions how in their research she found that only mice that were caloric restricted in their youth experienced longevity benefits while restricting calories in elderly mice saw no benefit in aging. I don't know if this has any relationship to the benefits in fasting for humans but it seems to me like the capacity of dealing with a stressor in mice is reduced.

Also had high blood pressure.

[@TheBradass]

I think this study just adds more ammunition to the arguments from the Mike Mentzer crowd. 14 day rotation with a 7 day split. Half the lifts to failure on day one, half the lifts done to failure on day 8. He recommended only a handful of exercises rather than the typical 3 variations of bicep curls approach you see guys using. He said the hardest part was not training more often because it felt wrong. If you'd like to see the results of this approach to giving a muscle 14 days of rest, the most notable would be the quadfather Tom Platz's legs when they were at their biggest. He would only work them twice a month but with extreme intensity. Mentzer also trained Dorian Yates. A lot of websites and fitness gurus ignore his teachings and throw their own spin on the training regimen leading to stunted growth and over training. Listen to the recordings he made if you want to truly grasp the approach.

[@limitisillusion7]

@@TheBradass I was actually talking down on Mentzer's approach not long ago. My argument was that it's easier to grow when you're on steroids. Then again, he trained that way while natural too. Other body builders trained with very high volume with similar results. It seems like there's more than 1 way to skin the cat per se. That being said, Mentzer didn't lift for longevity, he lifted to be huge, and huge he was, but he also died young. (probably due to steroids). If we take what these studies show, then too much strength training is not good for longevity. Nothing about these studies showed Mentzer's approach to body building was ideal to maximize muscle growth though. I still expect super low volume is not optimal, as there are lots of studies that support the 8-20 sets per muscle group per week. It's possible that Mentzer, Platz, and Yates had great genetics, great programming, great diet, or just a great steroid regimen. It's also possible that the amount of muscle mass you can build in a lifetime while strength training for 200+ minutes a week is just not great for longevity. That's the conclusion I lean towards. More muscle mass = more stress on your heart, and decreased lifespan. Bulk and cut cycles perhaps accentuate the muscle growth and stress on your heart. I will be cutting down another 10 pounds or so of fat to get to my lifetime body fat percentage. I already rewrote my programming after seeing this video to focus on strength. I'm happy with the amount of muscle mass I have, and I'm bigger than a lot of guys who are much stronger than me. Maybe I'll try a Mentzer hypertrophy approach once I get my strength up.

[@TheBradass]

@limitisillusion7 It's true that steroid use does allow you to pack on more mass and has been linked to an increased rate of cardiovascular issues. The cause of this increased rate of heart failure is thought to be the resulting myocardial hypertrophy, not the increase in lean body mass. That being said, I'm inclined to agree with you that increased body mass does increase cardiovascular stress. There's also something to be said for other health issues that arise. Obstructive Sleep Apnea, for example, is commonly glossed over as a contribution to poor heart health and is a condition which is so common among body builders that I've seen an increase in CPAP use recommendations on body building forums to people with no diagnosis by other people who also were never diagnosed. Steroid use actually shortens the training cycle because it speeds up recovery by promoting faster healing. It also requires either heavier lifts or higher volume to achieve failure. Mentzer's method wasn't quite so cut and dry as it always being a 14 rotation, he took an individual approach. If the person he was training could handle 3-6 day splits (which was often the case for endocrinologically enhanced trainees), he'd go that route but still closely monitored their results. I think it's worth mentioning that the magical 14-day time frame is respected by strongmen and powerlifters. They typically cut the weight being used down to around a third of their max for any days they train before a competition. This is just enough to keep practicing the lifts and movements while not stressing their bodies and no weight at all a few days from the meet. I'm really just trying to point out that you can use the 7 day split and achieve results, whether it's mass or strength gains while still staying within the weekly time limits talked about in this video.

This study was pretty generalistic and left alot of details out of the equasion.

So, even though I cannot give a definitive answer as I haven't done the research, just by looking at this study and compare it with my professional experience and knowledge I can already pretty much say that the answer that you are looking for is relative to the increase in training and dietary changes. Generally speaking the more you train the more calories you consume and the kinds of calories are also relevant. More proteins? Cholesterol? Saturated fat? All very relevant information, especially when talking about mortality in older people. I would bet money that all of these factors mentioned had a relevant impact to the outcome of the study, we know people who tend to work out a lot tend to experiment and delve into the more radical diets and we also know, thanks to studies in the blue zones, that more calorie intake has been associated with lower longevity. Overall this is my educated guess.

Some possible contributions to the statistical values: 1, people with health problems may be very motivated to do more exercice. 2, doing a lot of exercice cause the need for eating more often, which is detrimental to health. 3, a lot of exercise time in addition to work and other duties may cause elevated stress level. 4, a lot of exessice may interact with medications. 5, some persons who exercice a lot take unhealthy level of Supplements or illegal drugs to enhance their result.

[@andrewowens5653]

My thoughts: it seems to me that other factors could be at play here. Perhaps people who are willing to work out for extended periods of time are more likely to take steroids, which are illegal and dangerous. Since the diseases were talking about only express themselves in a small portion of the overall population, perhaps the weightlifters who take steroids threw off the whole study.

[@mariomenezes1153]

Keep in mind that it is not how long you live that is important but how much you enjoy life. If extreme exercise makes you happy, go for it. You could have been drinking alcohol, over eating or consuming drugs for pleasure and died earlier. Do what makes you feel good and you will hopefully not regret it on your deathbed 😊

[@pholzman2918]

Anything in this about intensity?? Also how do they define resistance training? The spectrum of what people do in the gym around the weights is tremendous. Seems like you shouldn't put those who do high rep low weight with those who low rep higher weight. Also, are you counting the minutes spent lifting in the workout or the total time you spend in the gym? Some people spend hours in the gym but only exercise for minutes.

[@CyberChud2077]

So my father spent the entirely of a 40 year career building statistical models. He always tells me that if some result seems really strange, they usually just did something wrong. For instance, when I first typed out this message, I typed "40 minute career" rather than "40 YEAR career." I almost didn't catch it. I wouldn't worry about this.

[@Forchintus]

Interesting data and I wonder if this is due to some self-selection effect where as people start to spend more time resistance training, they neglect cardio/start taking external hormones/take on other riskier activities? All-cause mortality can also be a weird proxy right, as it can include things like car-accidents? And isn't this 'too much exercise increases mortality' also true for cardio as well? Or maybe people who 'overdue' resistance training are in some group trying to 'gain' health after an adverse event and have worse outcomes in general? I'd love to see the meta-analyses drive more specific research to suss out the cause, and I appreciated you taking the time to talk about the sub-groups because I think you're onto something there.

[@drehenson8650]

I’m 41 and after 20 years of weightlifting 3 to 4 times a week I got an unexpected inguinal hernia despite having good form and not going crazy with heavy deadlifts or squats. After seeing this, I realize I would’ve been better off with less weightlifting and more cardio workouts.

[@TomiRantanen]

Interesting results and video. I'd guess people who spend hours at the gym each week are much more frequently the type of people who are never satisfied with themselves. Body dysmorphia, workaholism and a general unwillingness to stop and rest would certainly increase stress levels - on top of the acute stress from resistance training.

[@vtheory7531]

Also I think the longer someone spends in the gym lifting weights, the less time they’ll have to do cardio, which directly improves cardiovascular health.

[@polarvortex3294]

@@vtheory7531 Plus, of course, the longer they're in the gym, and at hard-core durations especially, the more likely they are to take steroids, insulin, growth hormone, etc., as well as suffer serious injury.

[@defeqel6537]

Also more likely to use heavier weights which by itself could be a risk factor

Some level of human health is “you use it you lose it”. Like you can take amazing care of your car and use the best premium oil and gas. Replace appropriate things and do maintenance early but if your using it then it’s gonna wear. Resistance training may be like racing your well cared for car. Not exercising, is just driving it around town.

[@marcospatchett]

Super interesting. I assume they controlled for confounding variables such as anabolic steroid use, high-protein diets or other variables potentially affecting lifespan among heavy lifters?

[@Physionic]

They did not, unfortunately.

[@hanksimon1023]

Interesting results. Non-backed up comments, possibly based on 30yo research that may be searchable OR may be out of date. 1. Research showed that Yoga performed once or twice a day increased Health Lifespan AND longevity. 2. Research showed that Tai Chi performed once or twice a day for 20 min each session also helped similarly, but not as much as yoga. 3. Implementation of Tai Chi recommendations and followup research showed that Tai Chi helped balance in seniors, unable to do yoga due to balance. 4. Also, Tai Chi was able to help some elderly, wheelchair bound patients regain mobility after 4 - 6 months of chair-bound, Tai Chi exercises. 5. Benefits did not kick in until after 20 min. for aerobic exercise, but declined after 40 min. 6. Natural bodybuilders may do [non-competition] maintenance lifting for only about 20 min. per session [body part split, or push-pull split] for 3 or 4 times per week. The one hour per day heavy workouts, especially pre-competition, are well-known [anecdotally?] to be detrimental [as is sub 10% body fat...]. I don't have any references for these. Some results came from Tufts University, Harvard University, and Cleveland Clinic Medical School... Old research...

[@gregfletcher2360]

I have a hard time concluding anything from this other than it's likely due to confounding influences such as steroids, bad diet, poor sleep, overworking the body into a state of constant inflammation. Grind culture etc is rife in the heavy lifter community and you don't need all of them to be doing it to skew results. However, it's interesting research all the same. Makes me think of contact sport athletes who are at peak physical fitness whilst they compete but come out of it with major injuries, brain damage etc. And yet, they were healthy af for a few years. They just overdid it

[@haroldpierre1726]

I've done resistance training for more than 30 years. While resistance training is great for mood, strength, and fitness, it can severely exacerbate minor joint injuries contributing to arthritis over the years. In retrospect, I should have lightened the weights, increased the reps, add Pilates, and I would be so much better off now.

[@C_R_O_M________]

Let's don't jump into conclusions and consider confounders (such as, for example, steroid use which is most likely the case with people who exercise more).

[@Physionic]

A great point, and certainly a possibility. My question, then, is how many people do you think take steroids of the people who lift more weights? If it's a smaller number like 5% or 10%, I doubt that would be sufficient to sway the entire data set upward. What do you think?

[@vtheory7531]

@@Physionicthere’s just a lot of factors at this point that in combination may skew the trend upward. I haven’t read the studies myself, but listening to the summary there were a lot of questions that came to my mind: -what is the resistance training program and overall exercise program these people are doing? Some people who spend a long time lifting weights in the gym often don’t have time or energy to do enough cardio for improving their heart health, which may contribute to the increased cardiovascular risk -what are the diets and recovery routines of the people in the study? Are they all the same, or different? -Along with the above, what optional supplements/steroids/etc do they use, if any? People who spend lots of time in the gym may be pro bodybuilders who are more likely to take risky drugs -What is their stress management like? I saw a comment that some people who spend a long time in the gym may have body dysmorphia/eating disorders or other similar mental issues which may affect their risk levels -what about the gender, race and ages of the people in the study? Is this trend universal? -how long was the study conducted for? A few weeks, months, years? There definitely needs to be more study done breaking down each potential factor before people should panic about these results.

[@C_R_O_M________]

@@Physionic it is, most likely, a smaller number of people that fall in the category of taking steroids. But that's just one of the confounders that might play a role. Another, as you, unfortunately, found out, could be injuries. Another could be nutrition or behavioral differences between groups (e.g. one group may have the tendency to take more risks - temperamentally) and so on. The point is that correlation is not causation as you perfectly know. If they haven't controlled for confounders, statistical significance is rather trivial.

[@smytharmstrong8543]

As mentioned in some comments below -- how does one define workout duration? If it's the muscle's time under tension then 60 minutes, for maximum health benefits per week, is a pretty heavy load. If each set (perhaps 8 to 12 reps/set) is on average 20 seconds in duration then one minute under tension equals three sets. Sixty minutes per week of muscle under tension equals 180 sets or 45 sets per work out if one were to exercise four times each week. One could easily spend 60 to 90+ minutes in the gym to complete 45 sets (4 to 6 + hours per week in the gym).

[@RonNorthcutt]

Great stuff (as usual). I think this validates both the importance of resistance training AND the importance of cross training (cardio, yoga, sport, walking, etc). As we see so often in life, variety and diversity are usually the ideal goal. I REALLY appreciate that you spoke not only about your bias, but also that you are going to do what is best for you (especially for mental well being). So often we see that people want a single path, but there is no "one right way to live". Genetic makeup, climate, diet, access, age, lifestyle, etc. all play a part and are always changing. Taking a step back, we know that a good goal is 150 min of moderate activity per week. For *some* people, that may look like 30-50% resistance training coupled with the rest coming from sports, yoga, walking, cardio, etc... which really seems like a great overall approach. I try to look at it as five 30 min "sessions" per week, with the possibility of multiple sessions in any given day. So, this really seems like further validation of the current popular advice, with the caveat that we should be mindful to look for multiple forms of activity... which is also pretty popular advice. Thanks again @physionic for making this data more broadly accessible.

[@berniesilvamusic]

If we assume that in "x minutes of muscle-strengthening activities per week", x is time under tension - which is a way more accurate measurement than time spent at the gym - 140min/week is *a lot*. Let's say that you're really serious about the gym and you go there 6x per week to do a standard push/pull/legs routine. You love the gym so much that you've binge watched Jeff Nippard's entire KZbin channel in a week, and now you're following his most recent "perfect pull workout". This workout includes 6 exercises, 3 sets each, in other words, 18 sets per workout/108 sets per week. If we assume that each set is on average 40 seconds long, that's 72 minutes per week of working out, which according to the graph has a very low increase in relative risk to working out 40 minutes per week. If you're doing "muscle-strengthening activities" for more than 72 mins per week: a) you're straining your body by doing a lot of junk volume, b) my intuition says that the likelihood that you're abusing steroids probably grows exponentially after that point. My analysis assumes that I'm right about the way they measured the amount of training per week, which assumes that low intensity activities like warmups, mobility training and low to medium intensity cardio are not accounted for. If my interpretation is correct, then this study tells us nothing new: exercising is good, overdoing it is bad.

This makes me glad I listen to Mike mentzer's way of training. Because Mike mentzer only trained for 30 minutes at the gym and he had the world's first perfect rating in bodybuilding. But I only train for 60 minutes to an hour and 30 minutes.

[@davidwelburn]

I did 90 minutes of weight training today, and I tend to do about that four times per week. But that's a fairly normal amount. Some people do a lot more. However, most of the time is resting time, of course, and some people take much longer rest periods than others, so how is that factored in? Still, this is concerning, and I'd like to find out more. Can't really see how I can shorten my workouts much, unless I only do a few compound exercises, and forget the rest. But that's not something I want to do.

[@embersandash]

Same here. I actually rest based on my heart rate. And I only push to absolute failure for one set per exercise one week out of every four.

[@moc5541]

Another KZbin guy, Dr. Brad Stanfield in New Zealand, recently commented, not about exercise but about observational studies in general, that the dose response curve is frequently cup-shaped (as shown here for cancer risk versus minutes of resistance training per week). He meant to imply, I think, that the shape may originate due to uncontrolled bias inherit in such studies.

[@haydengalloway5177]

I always strength trained twice a week for 30 minutes. I aim for more weight and less reps. This is because I was worried about joint damage. It seems joints aren't the only thing you need to worry about with excess reps.

Thats pretty backwards, higher intensity is generally harder on your joints lol
