Great post! I'm always looking for ways to blow up the wheels... but in the end I think a huge factor is being able to put in tons of time and super high levels of hard work into making this large Muscle group grow. Pushing past all levels and into another level of intensity.
It can be downright grueling and alot of people don't have the ability to go above and beyond like they should.
I know when I do some heavy leg work I give up up and say enough when probably I can do another set or 2.
But if you can handle the ordeal you will see promising gains!
