Comfortable armchairs with backs ruin our lower back
We continue study a book Daniela E. Lieberman Exercised.
Studying the life of hunter-gatherers in Africa and Latin America, Professor Lieberman noticed that they are on in fact, they spend a lot of time sitting in one place - for example, repairing a hunting equipment. At the same time, sitting in time is quite comparable to the labor of an office worker: that is, about 10 hours. This was measured using accelerometers attached to members of the tribe. But at the same time they noticed that the hunter never sits for more than 10-15 minutes motionless - he constantly gets up to stir the fire, drink water, go up to the child, to the tribesman.
That is, now scientists know for sure: physical activity is considered even from such minute movements and "fidgeting". We force our muscles to turn on. The sitting must be interrupted.
Where did 10 thousand steps a day come from? According to scientists, our ancestors walked about this much a day on average.
Almost everyone after a certain age back pain occurs. It turns out that one of the reasons is the comfortable chairs with backs. When a person sits on a bench or stool, he strains his back, exercising his muscles. And if there is no such need, then these muscles will gradually atrophy.
Therefore, we have no choice but to include exercises for the muscles of the back in our daily routine.
