The social determinants of health, such as socioeconomic status, education, and access to resources, significantly influence fitness levels. Factors like income affect the ability to afford gym memberships or healthy food options. Educational background plays a role in understanding health-related information and making informed choices. Additionally, living in neighborhoods with limited access to parks or fitness facilities can restrict opportunities for physical activity. These determinants create significant disparities in fitness levels, health outcomes, and access to supportive environments necessary for maintaining a healthy lifestyle.
