Subjective well-being and physical fitness are closely related. Individuals who engage in regular exercise often experience enhanced mood, reduced stress, and greater overall happiness. Improved physical health contributes to elevated levels of self-esteem and life satisfaction. Additionally, physical fitness can lead to better social interactions and relationships, further enhancing overall well-being. Conversely, low well-being can hinder motivation for physical activity, creating a cyclical pattern where lack of fitness negatively affects mental health. Thus, fostering both physical fitness and subjective well-being is crucial for a holistic approach to health.
