The Sit-Up Test is a physical fitness assessment that measures abdominal strength and endurance. During the test, an individual performs as many sit-ups as possible within a set time, usually one minute. Proper form is essential, with the participant lying on their back, knees bent, and feet secured. This test is commonly used in various fitness programs, including military and school fitness assessments. It helps evaluate core strength, which is important for overall physical performance and injury prevention. Results can be compared against established norms for different age and gender groups to assess fitness levels.
