Which of the following best describes the physical domain of Comprehensive Airman Fitness?

The physical domain of Comprehensive Airman Fitness primarily focuses on engaging in regular physical activity, which is essential for maintaining overall health and well-being. This domain emphasizes the importance of physical fitness as a contributing factor to an airman's effectiveness and resilience. Regular exercise not only enhances physical health but also positively affects mental and emotional well-being, contributing to overall readiness and performance.

While other domains, such as mental health strategies and spiritual wellness, are vital to comprehensive wellness, they do not fall within the physical domain's definition. Building relationships and support systems pertains more to social well-being, which is also an important aspect of overall fitness but is separate from the direct physical activity emphasized in the physical domain.
