Name one method of assessing flexibility.

The sit-and-reach test is a widely recognized method for assessing flexibility, particularly in the lower back and hamstring areas. This assessment typically involves sitting on the floor with legs extended straight ahead and reaching forward toward the toes, measuring how far the individual can reach beyond their feet. Flexibility is an important component of physical fitness, and the sit-and-reach test specifically evaluates the range of motion of the posterior chain muscles. It provides valuable feedback on an individual's flexibility level, which can be essential for injury prevention and overall athletic performance.

Other methods listed, such as the push-up test, 1-mile run test, and vertical jump test, evaluate different components of fitness, such as muscular strength, cardiovascular endurance, and muscular power, respectively, but do not measure flexibility directly.
