Human existence has changed radically over the last few millennia, centuries, and decades, and one of the most profound changes has been in our relationship to physical activity. Paleontologists and historical scientists agree that physical activity among humans is at its all-time historical
The health rewards of exercise extend far beyond its benefit for specific diseases. Exercise reduces blood clotting, lowers blood pressure, lowers cholesterol, improves glucose tolerance and insulin sensitivity, enhances self-image, elevates mood, reduces stress, creates a feeling of well-being, reinforces other positive life-style changes, stimulates creative thinking, increases muscle mass, increases basal metabolic rate, promotes improved sleep, stimulates healthy intestinal function, promotes weight loss, and enhances appearance. Furthermore, the ability of exercise to restore function to organs, muscles, joints and bones is not shared by drugs or surgery.
We have become a nation of convenience, developing technologies to reduce the amount of time and energy required for the even the most basic of human needs. While some of these advances have increased our abilities to achieve more, many of them have made much of the “work” obsolete. We as a species evolved and survived because we are able to be highly physically active, either in finding/harvesting food sources, fleeing predators, seasonal migrations or building shelters. Not only did this activity allow us to evolve; the human body evolved to best function under this lifestyle. Our cells, DNA, hormones and neurotransmitters, organs and nervous system all require physical activity to function properly. We are genetically adapted to live an extremely physically active lifestyle.
At least 30-45 minutes of exercise four days per week is the absolute minimum. If you have previously been minimally active for many years, you can start slowly with your new exercise program, gradually increasing the duration and intensity. With the simple addition of regular exercise to your routine, you will have significantly reduced
