       | Look at the first 4 bullet points that list the studies. Two of
       | the studies look at "recreationally trained men", one of the
       | study looks at untrained males, and only one study looks at "well
       | trained males". But for the well trained males, their 1RM max
       | bench press was ~100kg and 1RM max back squat was 120 kg. I
       | cannot even begin to fathom what male can not even bench 2 plates
       | and would consider themselves well trained with respect to weight
       | lifting. I do olympic lifts and power lifts, and literally the
       | first squat I ever did in my life with a bar on my back was more
       | than 120kg.
       | 
       | The general problem with bodybuilding knowledge is that literally
       | everything in someone's life will affect the results they get.
       | Their genetics. How their sleep is. How their stress levels are.
       | What kind of job they do. Whether they've trained before. Whether
       | they do other exercises. What their diet is like. All of that
       | will have an effect regardless of what you do in the gym. So
       | maybe someone hears slightly suboptimal advice about rest timing,
       | because the person giving it has the rest of their life on point
       | and appears to get good results from their suboptimal timing.

       | free time in my hands). During this time I would cook my own
       | meals, eat every 2 hours, workout at a gym and on the street
       | (street workout - calisthenics). I was able to get a 6 pack and
       | some muscles, but I failed to collect data about my process. Ever
       | since then, I dream about getting fat (which I did during the
       | pandemic) and then start the whole thing again, this time,
       | collecting data. I do have a lot of "bro" Knowledge (you get this
       | for free when you go to the gym regularly) but I would love the
       | get the science also.

       | The amount of contradictory advice slung online in regards to
       | fitness is immense. _(Same as it ever was, the old muscle
       | magazines were bad, too.)_ Lots and lots of "evidence"
       | amalgamated from rumors, second-hand sources, that old guy at the
       | gym, and teeny tiny studies that have never been replicated.
       | 
       | As you go on a fitness journey _(it hurt to type that)_ , you go
       | through decision paralysis, overbearing overconfidence that you
       | know what's up, and you end up with humility that boils down to

       | I think weightlifting (and also nutrition) have an intersection
       | between one's choices and the scientific literature. From what
       | I've seen of bodybuilders on youtube, there are many that base
       | their programs and recommendations on what they believe is
       | scientifically optimal. In most other areas of personal decision-
       | making, you won't find wisdom in academic literature. For
       | instance, remodeling your kitchen or dating. You might seek out
       | advice from various sources, but those sources probably wouldn't
       | include academic research.
       | 
       | The other thing about this article is that in using forums and
       | websites to gauge the view of the bodybuilding community, you end
       | up sampling more dedicated people who are interested in this sort
       | of discussion. There might be people following all sorts of weird
       | stuff ("woo") based on what their buddies at the gym are doing.
       | 
       | I wonder whether there are political issues where the
       | "literature" is ahead of where natural intuition is. For
       | instance, the minimum wage. Microeconomic intuition says raising
       | the minimum wage reduces the number of jobs available. I think
       | there are lots of studies out there saying that this intuition is
       | false. The minimum wage's effect on jobs is something fuzzier
       | than scientific fact however, and it kind of falls outside the
       | concept of metis too.

       | I find it -really- amusing that people forget that weightlifting
       | is an olympic sport. There have been -plenty- of studies on it.
       | The main issue tends to be that the russian protocols don't

       | 
       | Shorter rest periods are used for conditioning, not muscle
       | growth.
       | 
       | You can be a lazy slob and wait 3-5 minutes between each set. But
       | you'll be at the gym forever.
       | 
       | What these studies always completely fail to grasp is:
       | 
       | If I have 2hrs to do my workout, and I take 5 minutes between
       | sets, how much work am I going to do? What if I just took 1
       | minute between sets?
       | 
       | What if it's close to competition time? Do I want to be huffing
       | and puffing on stage? can I waste time with cardio or should I
       | cut rest time down between sets?
       | 
       | There's a lot of variables and not all of them are equating to
       | optimal muscle growth.

             | The brain does not directly drive the muscles. It does not

             | 
             | Second thing, healthy, fit people run for hours, bike for

             | and on without tire.
             | 
             | Yet just continually walking, uses more "brain telling
             | muscles what to do", than any single heavy lift plus even
             | perhaps 10 seconds of break.
             | 
             | Realistically, writing cursive with a pen, typing fast,

             | requires many different muscles all being used at once,

       | As someone who has been engaged in weightlifting for almost 30

       | 
       | I think the real goal would be to do whatever keeps you happy and

       | 
       | But there are additional factors at play. If a workout takes too

         | Muscle hypertrophy (as opposed to strength) follows a clear

         | 
         | If sets and reps are equated, sure resting longer is more
         | effective. In fact, if you are equating reps and sets in a
         | study, the longer rest group will have higher volume, defined
         | by sum of reps x weight, as the lower rest period group will
         | lift lighter because of increased fatigue. I find it hard to
         | believe many bodybuilders would disagree with that statement.
         | 
         | However, in real life, sets and reps will not be equated. You
         | use what time you have and maximizing volume wins (reps x
         | weight, assuming the weight is reasonably difficult).

         | In an ideal world for bodybuilders, perhaps they'd sit at the
         | gym for 2.5 hours to complete a workout, but people have lives
         | outside of lifting weights. Even pros.
         | 
         | Finally, the author seems to really think bodybuilders are by
         | and large clueless "bros". While this might be true for some, I
         | think the average bodybuilder consumes far more academic
         | literature than people involved in almost any other activity
         | outside of academia. Bodybuilders are on average fairly well
         | read and up to date on the scientific consensus thanks to
         | people like Mike Isratel, Jeff Nippard, Brad Shoenfeld, Brett
         | Contreras, Lyle McDonald, and Layne Norton to list just a few.

           | To a point. It also depends on your level of experience and
           | age.
           | 
           | Systemic volume also needs to be accounted for. Generally
           | speaking 10-20 sets per muscle per week. This can be from one
           | session or spread out over multiple sessions.
           | 
           | I'm 38, have been lifting weights for 20 years (do not and
