Improved physical fitness positively impacts quality of life by enhancing physical health, mental well-being, and functional capabilities. Regular exercise can lead to weight management, reduced risk of chronic diseases, and improved cardiovascular health. Mentally, it boosts mood through the release of endorphins, reducing symptoms of anxiety and depression. Enhanced fitness also increases energy levels and promotes better sleep quality. Furthermore, being physically fit improves daily activities, making them easier and more enjoyable. Collectively, these factors contribute significantly to an overall improved quality of life.
