Well, with regard to the views but not answering: I viewed but did not answer because it would be a very standard reply already known to many.
By the way your concept of Surge Workout Fuel isn’t remotely correct. I am sure you can find threads on it where you will find accounts of what actually happens.
As to the general problem, there are two aspects really:
A) The brain being able to generate more output in terms of making the body work hard
B) The body being able to work harder before various factors limit work, whether limiting the number of reps in a set or the number of sets one can do before too much cumulative fatigue has occurred.
Dealing with A, you have Power Drive and Spike Shooter.
Dealing with B, you have Surge Workout Fuel.
