I see we're all on the topic this morning, heh. I just finished reading the papers you linked, FF. Good stuff, ty.
The biggest thing I take away from it all is the remembrance of a principle I learned long ago: SAID, specific adaption to imposed demand. I.e. if you want to lift heavy weight you should train with heavy weight. If you want to move more mass per unit time, i.e. power, you should program to maximize the power you are generating in your workouts. And so on.
So for me, 61 and conscious of joint health and recovery ability, and preferring a full body workout every day, I choose sets, reps, load, perceived exertion, and fatigue management values that allow me to do a full body workout every day.
One other thing that occurred to me reading your links, I am still a believer in periodization, though the last paper calls it bogus. I
feel like I get better results if I go higher volume for one quarter and higher load for the next quarter. I do both intensely, to failure of strict form, which I guess roughly equates to 1RiR (one rep in reserve, a junk rep). Now I'm prompted to start a high load period for Q1 2022.
