City planning and infrastructure significantly influence fitness levels by determining accessibility and availability of recreational spaces. Well-designed urban areas with parks, walking paths, and bike lanes encourage residents to engage in physical activities like walking, jogging, and cycling. Conversely, areas lacking such infrastructure may deter individuals from being active due to safety concerns or lack of space. Additionally, proximity to fitness facilities, such as gyms and community centers, can impact exercise habits. Overall, thoughtful city planning can promote an active lifestyle and enhance community health.
