your extremely misguided if you dont think that increasing poundage increases muscle size.
the strength of a muscle is directly related to its area(size). scientific FACT.
let me make this a little easier for you to understand.
lets say you have a 20lb steel ball. you try holding it up with a regular size rubber band. the rubber band breaks. now you try a rubber band that is a half inch thick. holds up a little while, but it breaks . now you try a rubber band that is 2 inches thick, it holds the 20lb ball just fine.
or another example, you are trying to tow a 20 thousand pound trailer. first you try to tow it with a mazda miada. no luck. second you try towing it with a 1500 silverado. no luck. third you try a big rig. and it finally tows the 20 thousand pound trailer.
you need more machinery to handle bigger loads.
basic physics. retard
Youre assuming a muscle works like any of the other things in your example.
But this is easily disproven.. a miata wouldnt move that trailer ten feet, yet you have 150 lb twinks benching rediculous amounts, which negates youre whole theory right there.
It has a lot more to do with the how the muscle functions and interacts with other parts of the body, like someone else said, the CNS, leverage (Length of limbs) etc,
I dont know fuck all about the body or musculature, but this is plainly evident.
Youre doing exactly what I used to do, come up with a theory that fits your current experience and how YOU think people should train, and spread it as gospel, and it simply isnt truth.
Like someone else said, as you get older and accumulate more experience youll realize you dont know shit.
At least, thats what happened to me.
The more I learn, the more I realize I dont know shit.
