Which test primarily measures flexibility?

The Sit and Reach Test is designed specifically to assess an individual's flexibility, particularly in the lower back and hamstring muscles. It requires the participant to sit on the floor with legs extended straight and reach forward towards their toes. The distance reached serves as a direct measure of flexibility in these areas.

Flexibility is an important component of physical fitness, as it can impact overall performance in various activities, prevent injuries, and enhance quality of movement. Other tests mentioned, such as the Grip Dynamometer, the Standing Vertical Jump, and the 12 Minute Cooper Run, evaluate different physical attributes such as grip strength, lower body power, and cardiovascular endurance, respectively, rather than flexibility. This specificity makes the Sit and Reach Test the best choice for measuring flexibility.
