Which of the following is NOT a listed fitness domain?

• A. Muscular Endurance
• B. Flexibility
• C. Coordination
• D. Endurance

Answer: (D)

The idea here is how fitness components are named in this framework. Endurance by itself is too broad and is typically broken into two specific domains: cardiovascular (or cardiorespiratory) endurance and muscular endurance. Muscular Endurance is a distinct domain, Flexibility is a separate domain, and Coordination is another recognized domain. Since Endurance isn’t listed as its own separate category and instead ends up covered by the more specific cardio and muscular endurance domains, it’s the one that isn’t listed.
