What action can individuals take to positively impact community physical fitness?

Maintaining walking trails directly supports the infrastructure that enables community members to engage in physical fitness activities. Well-maintained trails encourage walking, running, and biking, which are essential forms of exercise that contribute to the overall physical health of the community. By helping to maintain these trails, individuals not only promote a more active lifestyle but also enhance access to safe environments for exercise. This action fosters a sense of community and encourages others to participate in physical activities, thereby amplifying the impact on community fitness.

The other options, while they may contribute to community well-being in various ways, do not have as direct a connection to promoting physical fitness. Starting a reading club focuses on cognitive engagement rather than physical activity. Growing a garden can promote healthy eating and may provide some physical activity, but it is not primarily aimed at enhancing community fitness through structured exercise. Organizing social events can bring people together but does not inherently encourage physical activity unless they are designed specifically around sports or physical challenges.
