I thought his views were very interesting. He argues for volume over intensity.
It sounds wonderful on paper but it doesn’t work. There is a critical intensity threshold you need to go above to elicit physical adaptation. What is that threshold? For lifting- about 70 % of 1 RM. Varies with the individual. Below that nothing changes.
If you do go above that threshold, changes happen quickly and you don’t need a lot of volume. People push these high volume workouts because they know people don’t like to hurt. With high volume it is the very last sets, when you are getting heavily fatigued, that cause growth. You essentially have pre- exhausted a lot of muscular fibers so the remaining ones go above the threshold to finish the movement.
If you like to spend time in the gym, do volume. If you want to spend as little time working out as possible, do intensity. If you want to get sick and weak, do high volume, high intensity.
