What is a common test to assess flexibility?

The sit-and-reach test is widely recognized as a standard method for evaluating flexibility, particularly in the lower back and hamstrings. During this test, an individual sits on the floor with their legs extended straight in front and then reaches forward as far as possible, ideally to touch or surpass their toes. This test effectively measures the range of motion in the hip joints and the flexibility of the spine, providing valuable insight into an individual's overall flexibility and potential risk for injury. This focus on specifically assessing flexibility is why the sit-and-reach test is a common choice in fitness assessments compared to the other options listed, which target different physical attributes such as strength or speed.
