We’re all born with near-perfect postural alignment. Watch a toddler walk, stand, reach overhead and squat and you’ll see tremendous mobility and safe strong joints.
It’s pretty much downhill from there.
North American culture has us spending an inordinate amount of time in the sitting position. A great deal of time and effort goes into preventing us from expending, well, time and effort when it comes to moving around in our daily lives. Items on shelves are always within arms reach, if we have to move very far we hop on an escalator, an elevator or get in our cars; and a job that involves spending much time on one’s feet or lifting something heavier than twenty pounds is considered “strenuous.”
Over the course of a lifetime, people tend to develop postural imbalances. Much of this is due to the chair-bound culture. The head tends to drift forward into the dreaded “turtle head” posture; the lower back sways into a position known as lordosis, the upper back hunches forward, the scapulae wing out, the upper arms rotate internally and the palms end up facing backwards like Fred Flintstone, the knees get wobbly and the hips get tight, and the ankles become stiff and crunchy.
No part of the body functions in isolation. The entire body is connected through a variety of means.
A Symphony, Not a Solo
Muscles do not contract individually; they do so in a synchronized fashion, like a symphony. If you bend down and pick your kid off the floor, a chain of muscular contractions from your feet all the way through your arms occurs in order to make that happen. When the body has a postural imbalance, these “kinetic chains” are forced to be directed through an inefficient and potentially harmful series of muscular contractions.
