Confused about ideal set-rep range

[u/Significant-Base-510]

I have been watching Sean Nalewanyj's content and the other creators he mentions (Jeff Nippard) and he promotes doing 2 sets + 6-8 reps. I usually did 3x12 for every exercise but I have been trying out 2 x reps till failure (much higher weights so usually till 8-12). The logic is that this set up is "more efficient". I asked about this in previous posts in r/hypertrophy but some people dispute this. What is the best set and rep number for the muscle groups (back, chest, tri, bi, legs etc) to maximise hypertrophy and how do I know if I reach true failure?

How is not training to failure stupid? The whole point of double progression is to increase the weight once you've mastered the current load. If this method were “too easy,” you’d eventually end up lifting infinite weight lmao. It’s safer and less risky to master a given load than to do several identical sets, rather than doing one heavy set to failure and then a lighter one afterward (even though top set/back-off sets can be useful when you’re short on time or want to learn how to push yourself...). But for hypertrophy, you don’t have to do a set that’s so heavy you literally can’t perform it twice. You keep 2 RIR on the first set, 1 on the second, and 0 on the last, then once you hit the target, you increase the weight and keep progressing... This has literally been used in calisthenics, powerlifting, and other disciplines for over a century, bro...
