There is a difference between hearing the term dysfunctional and "not functional." Do you understand the difference? No? Well let's discuss this a little.
The only times I've ever heard "not functional" is when people talk about movements; they'll never say "such and such exercise is dysfunctional." Saying "not functional" is the norm. Some fitness enthusiasts will lambast a movement, lets say curls, for "not being functional." This style of usage is much more popular when it comes to discussing the functionality of something in the fitness industry nowadays. So much so that it has redefined the term "functional."
Well what about the term "more functional." Most commonly used when justifying the decision to comine exercise X with exercise Y while standing on surface Z. If you're reading this chances are you understand the stupidity of trying to combine an endless amount of exercise variations in order to achieve maximum functionality. That's chasing the dragon.
I'm sure you see where this is going, and I'm sure you have heard the most common rebuttal to this kind of stupidity, "Strength is most functional." But is there anything more functional than strength?
But how? How is swole more functional than doing a pistol squat on a bosu ball while doing 100 reps of one arm bottoms up kettlebell presses. How is swole more functional than strength?
Those are easy questions to answer.
Sex. That's how.
Swole will get you laid, and that's functional because that ensures the survival of our species. Not only that but it improves mood and general feelings of wellness. Sex is the pinnacle of importance. Sure, being strong will get you swole, or hell, maybe you somehow got swole doing all that silliness at your box down in the industrial zone of downtown. But how you got to your current state of swoleness doesn't matter to the opposite sex.
Only your swoleness matters during initial attraction- and that's what ultimately leads to sex.
Therefore any movement is functional so long as it leads towards an improved state of swoleness. The only things that are "not functional" are those things which lead a person away from swole.
Finally what is more functional than swole?
