The Sit and Reach test assesses which component of fitness?

• A. Harvard Step Test measures Aerobic capacity
• B. Sit and Reach measures Flexibility
• C. Illinois Agility Test measures Agility
• D. Flexed Arm Hang measures Upper body endurance

Answer: (B)

Flexibility is being assessed here. The Sit and Reach test measures how far forward you can reach with legs extended, which reflects the flexibility of the posterior chain—primarily the hamstrings and lower back. A greater reach indicates greater flexibility, since it shows how much range of motion you have in those muscles and joints. This test focuses on steady, controlled movement through a range of motion rather than heart rate or speed, so it’s not about aerobic capacity (which is assessed by tests like the Harvard Step Test), agility (the ability to change direction quickly, tested by agility drills), or upper-body endurance (the endurance of arm and shoulder muscles, tested by exercises like the Flexed Arm Hang). The Sit and Reach is a simple, standardized way to gauge flexibility specifically.
