Weve observed that every quantifiable measure of health that typically declines with age is improved by exercise. Furthermore, these measures can be placed on a continuum that ranges from sickness to wellness to fitness. From this view fitness is seen to be a hedge against sickness. Blood pressure, body fat, bone density, triglycerides, good and bad cholesterol, flexibility, and muscle mass each follow this pattern. Done right, fitness provides a nice margin of protection against the ravages of time and disease. Fitness is and should be super-wellness.
