What is a common measure of flexibility?

The sit-and-reach test is a widely recognized measure of flexibility, particularly in the lower back and hamstring areas. This test involves sitting on the floor with legs extended and reaching forward towards the toes. The distance reached is then measured, providing a quantifiable metric for flexibility.

This test is popular because it specifically targets the flexibility of the posterior chain, which is critical for overall physical performance and can influence other physical activities. By assessing how far participants can reach, fitness professionals can evaluate an individual's range of motion and identify areas that may need improvement through targeted stretching or flexibility training.

Other tests such as the wall sit test focus more on endurance and strength rather than flexibility, while push-up tests assess upper body strength. The squat test evaluates strength and mobility in the lower body but does not specifically measure overall flexibility.
