How It Works

Flexibility is the ability of a joint to move through its full range of motion. It is joint-specific — being flexible in your hamstrings does not mean your shoulders are flexible. The sit-and-reach test measures hamstring and lower back flexibility and is the most commonly used flexibility test in fitness assessments. Values are measured in centimeters past the toes (positive) or before the toes (negative). The shoulder reach test (Apley scratch test) measures shoulder mobility by reaching one hand over the shoulder and the other behind the back — the distance between fingertips indicates flexibility. The Thomas test for hip flexors measures the angle of hip extension while lying on a table edge. Women are generally more flexible than men due to hormonal differences affecting connective tissue. Flexibility naturally decreases with age but responds well to consistent stretching. Static stretching (holding 30-60 seconds) after exercise is most effective for improving range of motion. Dynamic stretching before exercise improves performance without the temporary strength reduction that static stretching can cause.
