PUSH AND PULL: THE ART OF SELF-MONITORING

Endurance athletes new and old are often unsure of how frequent, fast, or hard their runs should be. In order to make fitness gains without getting sick or "burned out," all runners must learn to balance the intensity and length of their workouts with proper doses of rest.

Surveys reveal that the vast majority of people undertaking exercise programs quit within one month. The main reason? Too much, too hard, too soon. Believing in the American "no pain, no gain" fallacy reinforced by, for example, gym-class running for punishment rather than recreation, they're apt to force themselves through more than they can realistically handle, not understanding that even healthy young folks are advised to mix equal amounts of running with walking when first getting aerobically fit. If they've been in shape in the past, they're discouraged at what they feel they've physically become. As a result, they get discouraged and stop working out, soured by the experience and believing they "aren't cut out" for running.

Everyone with the willingness to run a step is a runner!
