According to the Centers for Disease Control and Prevention, being physically fit keeps bones strong, supports cardiovascular health, reduces the risk of chronic diseases and increases a person's overall life expectancy. Achieving physical fitness also improves mental health.
Regular physical activity along with proper nutrition are essential for achieving physical fitness. According to the President's Council on Fitness, Sports and Nutrition, engaging in at least 30 minutes of physical exercise daily can help adults become physically fit. Regular physical activity promotes muscle and joint strength, minimizes weight gain, strengthens the heart and lungs, improves sleep and reduces the risk of chronic diseases, including cancer and heart disease. Regular exercise also promotes mental fitness by elevating a person's mood, which reduces their risk of depression, according to the Centers for Disease Control and Prevention.
A person who is physically fit also enjoys a better overall quality of life. The University of Minnesota's Center for Spirituality and Healing notes that physically fit individuals tend to have better social lives and stronger relationships. They often have an increased sense of purpose, higher self-esteem and positive attitudes. Children who are physically fit achieve these benefits as well. The President's Council on Fitness, Sports and Nutrition recommends that children engage in at least 60 minutes of physical activity daily to achieve physical fitness and good health.
