Regular exercise induces numerous changes in the body, contributing to enhanced physical fitness and overall health. Initially, exercise promotes cardiovascular efficiency, improving heart rate and blood circulation. It also strengthens muscles and bones, enhancing strength and endurance. Metabolism benefits from exercise by increasing calorie burn and fat loss, promoting a healthier body composition. Additionally, regular physical activity influences mental health, reducing symptoms of anxiety and depression while boosting mood-enhancing hormones like endorphins. Engaging in exercise leads to holistic improvements, forging a healthier lifestyle and promoting longevity.
