gymrats are always thinking there is some secret stack or routine that will get them bigger, the fact is the insertion of the muscle decides how big its going to be, if you have high insertions on a bodypart it will never look impressive as a bodybuilder who has low insertions no matter what you do, do we accept this reality no we rather search for the magic routine that will make it freaky, that is why no one can spill his bullshit.
The fact is if you do his routine or HIT or high volume after a year you all will look the same.
