We have photographs and scientific evidence that our ancestors until early in the 20th century used their bodies well in everyday positions and movements. And in fact, there still exist populations in much of the pre-industrial world where everyone has beautiful posture and strong, graceful physiques.Share
The flapper age in the 1920s, the breakdown of kinesthetic transmission across generations with family members no longer living close to each other, and the poor design of most modern furniture have all contributed to the disastrous habit that most of us have of tucking the pelvis (curling our tails under us). Realizing this was causing people to hunch, someone came up with the idea of lumbar support and lumbar curvature. Well, terrific – now we have two problems instead of one. Now not only are most people still sitting with a tucked pelvis (which is damaging for the L5-S1 disc and indirectly leads to a whole host of other problems, including hunched shoulders, forward head, misaligned legs, and muscle imbalances), but they are also ending up with swaybacks. Conventional wisdom has come up with all sorts of devices and exercises to promote the S-shape spine, which is now considered the normal shape for the spine. Well, just because S shape is the norm in our culture does not mean it’s healthy! We have to stop mistaking average for normal. And we certainly have to stop mistaking average for ideal! After all, would you settle for the average body fat percentage in our culture? I didn’t think so.
