Which type of activity can assist in improving physical health?

Engaging in group exercise classes or walking clubs plays a significant role in improving physical health because these activities encourage participants to be physically active in a supportive and social environment. Exercise is well-documented in its benefits to physical health, including enhancing cardiovascular fitness, improving muscle strength, aiding in weight management, and increasing flexibility. Additionally, social settings, such as group classes, can provide motivation and accountability, leading to increased participation and adherence to a physical activity regimen.

Other activities listed, such as watching films, reading books, or sitting silently, do not promote physical movement and, therefore, do not contribute to physical health improvements. While they may provide mental stimulation or relaxation, they lack the physical exertion needed to enhance one's physical well-being.
