reliability: The reliability of this test will depend on the amount of warm-up that is allowed, and whether the same procedures are followed each time the test is conducted. Most sit and reach testing norms are based on no previous warm-up, though the best results will be achieved after a warm up or if the test is proceeded by a test such as the endurance test which can act as a warm up. If a warm up is used, it is important to have a standardized warm up and test order and repeat the same conditions for each time the test is conducted.
