Physiological adaptations from exercise, such as increased muscle strength, flexibility, and improved cardiovascular function, greatly enhance quality of life. These adaptations lead to better mobility, making everyday activities easier and less fatiguing. Additionally, exercise stimulates the release of endorphins, which can improve mood and mental well-being. Enhanced overall fitness also allows for greater participation in social activities and hobbies, further enriching life experiences. In short, regular exercise significantly contributes to a higher quality of life.
