Moderate exercise refers to a level of physical activity that is not too intense, but still provides health benefits. It typically involves activities such as brisk walking, swimming or cycling at a steady pace, and can help improve cardiovascular fitness, strengthen muscles, and boost overall well-being. Moderate exercise should be comfortable enough to carry on a conversation while performing it, but still requires some effort. It is recommended that adults engage in at least 150 minutes of moderate aerobic activity or 75 minutes of vigorous aerobic activity each week for optimal health benefits.
