A lot of people in my experience also screw up on multiple fronts with this protocol as well.
The first being that theyd don't hit muscular failure because they are using exercises that are dangerous to go to failure with
The second, people are not actually training the whole body. Forgetting the neck, forearms, psoas, etc. This dampens the hormonal response as well.
Third, they are doing too much on rest days. People are trying to add in all kinds of extra volume, slowing recovery.
