How often should individuals engage in physical activity for optimal health?

Engaging in physical activity at least three times a week is recommended for optimal health because regular physical activity helps improve cardiovascular fitness, muscle strength, flexibility, and mental wellness. The Centers for Disease Control and Prevention (CDC) and other health organizations suggest that adults should aim for at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity activity each week, supplemented with strength training on two or more days of the week. This frequency allows for consistent health benefits, including maintaining a healthy weight, reducing the risk of chronic diseases, and enhancing overall wellness and quality of life. Regular activity helps establish exercise as a habit, making it easier and more effective in achieving long-term health outcomes.
