Fitness is directly related to quality of life as it influences both physical and mental well-being. Regular physical activity improves cardiovascular health, strengthens muscles, and enhances flexibility, contributing to better overall physical health. This can lead to reduced risk of chronic diseases such as heart disease and diabetes. Enhanced fitness levels also promote better mental health, including reduced symptoms of anxiety and depression. Furthermore, being physically fit often leads to increased energy levels, improved sleep quality, and a greater sense of well-being, all of which significantly enhance one’s quality of life.
