Markers of good mental health related to fitness include improved self-esteem, resilience, and positive mood regulation. Engaging in regular physical activity often leads to the release of endorphins, which can alleviate symptoms of anxiety and depression. Furthermore, achieving fitness goals—whether big or small—can enhance self-confidence, fostering a sense of accomplishment. Regular exercise can also promote better sleep and stress management. Overall, maintaining physical fitness is closely linked to sustaining mental well-being and fostering emotional resilience.
