We know that our ancestors spent an average of several hours each day moving about at what today’s exercise physiologists might describe as a “low level aerobic pace.” They hunted, gathered, foraged, wandered, scouted, migrated, climbed and crawled. This low level of activity prompted their genes to build a stronger capillary (blood vessel) network to fuel each muscle cell, to be able to store some excess food as fat, but also to be readily able to convert the stored fat back into energy. Of course, they did all this without the benefit of paved sidewalks or comfortable shoes. Because every footfall landed at a different angle, every muscle, tendon and ligament worked and became stronger together in balance. Note that they did NOT go out and “jog” at 80% of their MAX Heart Rate for long periods of time as Conventional Wisdom suggests today!
Today we do some form of low level aerobic activity 2-5 hours a week, whether it is walking, hiking, easy bike riding or swimming. Ideally, and when possible, find time to go barefoot or wear as little foot support as possible. Low-level activity is necessary (especially if you find yourself chained to a desk every day). The combined effect will be an increase in capillary perfusion, fat-burning and overall integration of muscle strength and flexibility.
