120 reps weekly is exorbitantly high, in my view. The sources you provided in your previous post were based largely on anecdote and the intuition of weightlifting coaches and enthusiasts. To me, these sources don't exercise much scientifically and don't provided thorough citations. Therefore, I don't think they are appropriate for someone pursuing scientifically optimal health and wellness through nutrition, lifestyle and training, which would be the goal shared by most on this board. For this aim I would point you to "Body By Science" or even "the 4-hour body" by Timothy Ferris. The former delves into many of the scientific aspects and is heavily cited, while the latter is admittedly more anecdotal but well still well supported as it alluded to Arthur Miller's training with Casey Viator who was able to gain nearly 40 lbs of muscle with on 1 work out each week (though steroid usage was denied), and the result is a strong case for lowering volume and frequency in ostensibly every weightlifters workout. Body By Science even details how subjects improved in many ways simply by lowering their training frequency from 3 times per week to once per week.
That said, if hyperophy is the goal then some of the "bro-science" routines detailed in your links could be optimal, but I would never recommend them to anyone because they will compromise structure and metabolism long term. After all, all weightlifters and bodybuilders end up with joint pain, injuries, back problems, etc etc. To avoid this I would never train to failure and never perform more than a single 30 minute routine for any given muscle group per week, and I don't consider biceps or triceps to be a muscle group, the arms fall into the push/pull categories from my perspective, as they are always working in conjunction with the large muscles. 120 reps per week should be cut in half, or even a quarter. Besides, muscle growth is mainly achieved through dietary protein, this was proven by multiple time Olympian Dorian Yates who asserted that 80% of bodybuilding is diet, and that his lifting never lasted more than 30 minutes with a couple intense sets per muscle, but mostly warm-up sets.
Your assertion that these programs are all based on anecdotal evidence is false. You also seem to believe in programs founded on the success of infamous steroid abusers like casey viator who founded his training principles on the Colorado experiment (of which my Uncle was actually a participant in) and Dorian Yates who used ridiculous amounts of steroids and followed the heavy duty training principles and rest pause made popular by the mentzer brothers (also known steroid users) which was not founded in science but by anecdote and is more risky for injuries due to over training than any of the things I outlined above. Your opinion of me suggesting too much volume itself is anecdotal if you have no solid science to back it on

Juggernaut -BECOME UNSTOPPABLE
These links are to organizations which provide more in depth insights on training methods than the links I posted earlier and provide free training templates. I've been coached by someone from each of these groups and their training methods are all based on the same science as the earlier links I posted, just more in depth and articulate in their approach along with more concise timing of phases. These organizations also specialize in drug free athletic coaching as their athletes compete in drug free federations which are easy to prove based on taking any of the athletes and testing their FFMI for yourself.
This video is eric helms (phd) giving a quick but concise lecture on appropriate volumes, intensities and frequencies, and gauging RPE, and though he doesn't exactly outline what I have above for my own personal use, it's still very close and probably tailored to a safer recommendation for novice viewers who are going to do the maximal volume despite best suggestions:
I have looked at other studies on optimal training volumes and overtraining and found the figure of 120 reps per week being the max for an advanced trainee but it's late and I don't feel like digging it up so I'll do it tomorrow. Hopefully this helps explain my suggestions more throuroughly.
