What is the appropriate sequence for fitness testing?

Placing flexibility first is incorrect because flexibility measurements are more accurate and safer when muscles are warmed up, which happens during later stages of the testing sequence.

Performing cardiorespiratory endurance testing before body composition is incorrect because the exertion and sweating from cardio testing can alter skinfold and other body composition measurements.

Body composition assessments (such as skinfolds or circumferences) are performed first because they are non-fatiguing resting measurements that should not be influenced by prior exertion. Cardiorespiratory endurance testing follows, then muscular fitness, with flexibility testing placed last since muscles are most pliable after being thoroughly warmed up from prior tests. This sequence minimizes the physiological interference between tests and ensures the most accurate results for each component.

Placing flexibility before cardiorespiratory endurance testing is incorrect; flexibility should come last in the sequence after muscles have been adequately warmed through prior exercise components.
