A lifestyle that includes regular exercise can enhance individual performance. Sensible exercise also improves circulatory efficiency and cardiovascular conditioning, which in turn will improve your endurance. While all aspects of fitness are important, aerobic fitness has the greatest impact on the quality of sleep and stress management. Exercise provides many physical benefits and it also contributes to an overall sense of well being. Rather than reaching for a candy bar the next time you’re experiencing an energy shortage, reach for your walking shoes. A brisk 10-minute walk should provide you with a significantly better energy boost than any candy bar. And unlike a candy bar, walking won’t make you a victim of fatigue an hour later.
