I understand the inroad argument. My only question is, How much inroad is necessary? I don't pretend to know the answer. This is why I asked if you compared shallower and deeper inroading for a given level of frequency. Remember what Arthur Jones said about not trying to find out how much exercise you can tolerate, but how much you actually need. That argument can apply to each of volume, frequency and intensity, as well as in combination.Yes. It's better because it makes a deeper inroad into the muscle fibers than the other methods of training. With proper rest and nutrition, this will create more muscle growth than other methods that create a shallower inroad.
As an aside, you will recall one of the findings in the study I attached in a previous post:
I understand if you do not necessarily accept the study findings at face. But I'm trying to reconcile Darden's HIT evolution. In the earlier link to a thread on his web site, Darden was in agreement with Drew Baye, who echoed Arthur Jones's position on rep speed. This rep speed was nowhere close to approaching a 30-30-30 style.• After performing a combination of concentric and eccentric muscle actions, terminate each exercise at the point where the concentric phase of the exercise is becoming difficult, if not impossible, while maintaining good form. There is very little evidence to suggest that going beyond this level of intensity (e.g., supramaximal or accentuated eccentric muscle actions) will further enhance muscular strength, hypertrophy, power, or endurance.
As I posted some time ago in another thread, Darden wrote in a 2010 thread on his web site that he applies once-a-week training to most (but not all) of his clients. He explained that these were whole-body routines composed of 8-9 exercises performed in the high-intensity style. Nowhere does he or anyone else refer to a 30-30-30 cadence until the very end of the thread on the sixth page. Here is a link to the thread:

It seems like he just mentioned it in response to a question about "specialization" rather than as a standard workout protocol.
