For hypertrophy, the primary driver is performing sufficient hard sets that apply mechanical tension to the muscle, rather than necessarily taking every set to failure.

“doesn't really matter for muscle growth because it's really just about doing enough hard sets and putting that mechanical tension on the muscle”

“as far as like um hypertrophy I think that force is probably less important I think it's more about just having s enough sufficiently hard sets however you slice that”

“what seems to be important for building muscle is a few things the first is mechanical tension and understanding that mechanical tension is cumulative throughout reps and sets... the research seems to suggest for a muscular hypertrophy you have to get within a few reps of failure to really maximize the response”

“mechanical tension number of hard sets and muscles at long lengths meaning uh there does seem to be quite a bit of research that even when you equalize for proximity to failure if you aren't taking a muscle to a long length under tension you're probably not maximizing the benefits of it”
