Light physical activity plays a critical role in overall fitness by enhancing metabolic health and maintaining mobility. Engaging in light activities, such as walking or casual cycling, helps to increase daily energy expenditure, thereby aiding in weight management. Furthermore, such movements contribute to improved cardiovascular health and can significantly enhance mental well-being by reducing feelings of anxiety and depression. Regular light activity also encourages consistency in a fitness routine, thereby serving as a gateway for individuals to engage in more intense forms of exercise over time.
