Long story short, failed reps get much more risky and problematic as the weight you’re lifting approaches your 1RM.
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
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.
I trained myself to do pull-ups using this method, repeatedly lowering myself in a controlled motion from the top position while I was too weak to actually pull myself up.
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.
Like why not make a study to see if its more nutritious to eat dinner in 15 or 20 minutes?
Stereotyping, weightlifters who go for max numbers do 1 set of a million pounds and rest three hours between exercises, while bodybuilders do thirty exercises a day for 8 series of 15 reps each.
All of these benefit from weight training, but depending on the sport, the programming will be very different.
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.

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.
Body builders typically advise spending about a year doing few (~5) reps per set to build strength, and then switch to longer sets (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.
No pain, no gain.
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.
Dynomight has a good blog post about this[0], but applied to running rather than resistance training.

Not sure how much can be concluded from this.
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

I've f.up my MCL by not listening to my body and I have the stability of a typical 85 year old while I try and 'heal'. It takes longer as you get older (you're probably not 20 year old) and stupid stuff can really take you out.

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
