Exercise is very important for both men and women. It makes the body fit and beautiful, improves mood, and helps prevent heart disease. Regular exercise, such as three days a week for 30 minutes, reduces the risk of heart problems, so developing an exercise routine before age 40 is important. Maintaining health and life requires effort. While modern life involves more mental exertion, physical exercise is still needed to keep the body strong. Developing an exercise habit helps support health.
