This includes incorporating a variety of activities that promote cardiovascular fitness, strength, flexibility, and balance, while also avoiding injury and overexertion. Healthy exercise can benefit overall health by reducing the risk of chronic diseases, improving physical and mental well-being, and promoting a healthy weight. It's important to listen to your body, set realistic goals, and work with a qualified fitness professional if needed to develop a safe and effective exercise program.
