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.

> Loads for each set were adjusted to ensure that volitional fatigue was reached within 8–12 and 20–25 repetitions for the HL and LL limbs, respectively 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…

This is spoken like you've never done any reps at all?

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).

Can we replicate the process of reaching muscle fatigue/failure to spur muscle growth without the strength training or anabolic steroids? Think GLP-1RAs but for this specific biological pathway. https://www.biopharmadive.com/news/lilly-terminate-obesity-t... https://www.sciencedirect.com/topics/medicine-and-dentistry/...

My understanding is that anabolic steroid are somehow close to what you're thinking about? It's just that as anything taking a simple shortcut , it comes with unwanted effects

Sounds like a great way to injure yourself, also would only work for eccentric motion

To me it doesn't sound much different than "taking your sets to muscular failure".

Not all muscles resist extension, some do the opposite and contract.

I.e. No pain, no gain.

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 lev…

Yeah, "no pain no gain" is probably the worst advice I've ever received. It encourages sedentary people to go hard for a week and then quit, which is the exact opposite of what works: starting with consistent easy sessions and adding progressive overload.

Dynomight has a good blog post about this[0], but applied to running rather than resistance training.

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…

This is par for the course with exercise science. It's mostly fake. No blinding, small sample sizes, researchers with agenda, low duration, low funding etc. The good news is that doing almost anything works.

I feel like I would definitely notice if I went from 12 to 25 reps on any exercise I do. Although typically I max out at 8 before adding more weight.

> 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.

is "8-12" not "few" for you?

There's not much difference in hitting max at 12 and at 25, from anecdotal experience. The study corroborated that as well, even though with small n.

tldr appears to be that if you work to fatigue it doesn't matter if you fatigue out with high weights vs low weights

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
