Name a common normative test for flexibility used in CSCS practice.

• A. Timed jump test.
• B. Agility ladder drill.
• C. 90-degree sit-up.
• D. Sit-and-reach test with age/sex normative values.

Answer: (D)

Flexibility testing is about measuring how far a joint or muscle group can move and then comparing that result to typical values. The sit-and-reach test with age/sex normative values does this by assessing hamstring and lower-back mobility and providing standard reference data for different ages and sexes. That combination lets you see where an individual sits relative to a population, turning a raw measurement into meaningful, interpretable information for training decisions. The other options measure different qualities—power, agility, or core endurance—not flexibility in a way that offers normative benchmarks by age and sex.
