What is the primary goal of the recommended exercise duration and intensity?

The primary goal of the recommended exercise duration and intensity is to improve cardiovascular health. Regular aerobic exercise, which is often emphasized in exercise guidelines, has been shown to strengthen the heart, improve blood circulation, and enhance lung capacity. Engaging in moderate to vigorous physical activity for the recommended duration can help lower the risk of heart disease, hypertension, and other cardiovascular conditions.

While weight loss, building muscle mass, and enhancing flexibility are important aspects of overall fitness and health, they are often secondary benefits derived from improved cardiovascular health. For instance, engaging in cardiovascular exercises can contribute to weight management and metabolic health, but the main focus of these guidelines is on how such exercise positively impacts heart function and overall cardiovascular system efficiency.
