A great deal of what we perceive as poor posture is end result of biological adaption over decades and is unlikely to change without a totally heroic effort and not even then. In principle, humans can conform to almost anything in fact, its the law.44 However, the same principle dictates that change is slow and hard.
Wear high heels for many years, plus your calves really shorten,45 and also not clear how easily that can be undone. On his or her other hand, grow up climbing trees like the Twa people of Africa and may earn amazingly limber calves that allow your ankles to bend halfway (45) towards the shin46 2-4 times as compared to the average urban person! Look at them go:

Squatting like a baby can be a faddish fitness goal and hopelessly unrealistic for most people. But if you grow up squatting since the Hadza bushmen, its no hassle!

As Todd Hargrove puts it, not do available squat exactly like a baby, they squat better than a infants.
They maintained all the mobility they'd as babies, but added strength, stability and competency.
They never stretch, never do yoga or pilates, never caught up by any corrective exercise, yet they all move effortlessly in and out of positions that a majority of Westerners cannot even break into.
Which sounds great. But dont think for a second that the Twa and also the Hadza do not own their own costs and consequences for the stresses theyve adapted so beautifully returning to. Everything in biology involves trade-offs.
Many adaptations are most definitely irreversibleor so hard that may possibly as well be. A child can adapt approaches that are possible only in the plasticity to a rapidly growing body, and also for the adult to try to undo it is trying to straighten wood that used to be artfully bent with .
Other changes may occur only over vast spans of time, or as variables we have little or no control over. The result is that some adult postures are simply impossible to change not enough do get locked present in.
And yet we can change. Stretch actually can increase flexibility, with a lot of work (more on this below), for whatever it is worth. For that office worker who feels locked into a typists hunch I realize I do, as I type this isnt it worth at least trying in order to out? Is the near futility of all of it the more reason to at least make the trouble? Perhaps it is..
