Exercise is crucial for health because it helps maintain a healthy weight, strengthens the cardiovascular system, and improves mental health. Regular physical activity burns calories, which can help prevent obesity, and enhances the efficiency of the heart and lungs. Additionally, exercise releases endorphins, which can reduce stress and improve mood. It also supports muscle and bone strength, helping to prevent injuries and conditions like osteoporosis.<|im_end|>
