A common way to assess flexibility is through the sit-and-reach test. This test measures the flexibility of the lower back and hamstrings by requiring an individual to sit on the floor with legs extended and reach forward towards their toes. The distance reached is compared to standard norms to evaluate flexibility levels. Regular assessments can help track progress in flexibility, which is essential for overall physical fitness and injury prevention. Improving flexibility enhances movement efficiency and promotes better performance in various physical activities.
