The United States Air Force Fitness Test (AFFT) is designed to test the body composition, muscular strength/endurance and cardiovascular respiratory fitness of airmen in the United States Air Force. As part of the Fit to Fight program, the Air Force adopted a more stringent physical fitness assessment; the new fitness program was established on January 1, 2004, and replaces the annual ergo-cycle test that the Air Force had used for several years.  Some reports state that participation at fitness centers is up 30 percent since the new program was established. In the AFFT, Airmen are given a score based on performance consisting of four components: waist circumfirence, the crunch, the push-up, and a 1.5 mile run. Airmen can potentially earn a score of 100; a passing score is anything over 75 points.  Members must complete all components unless medically exempted. If medically exempted from any component, the total score is calculated as follows: Total Component Points Achieved X 100 divided by total possible points .
Maximum component points are:
- Aerobic -- 50
- Body Composition -- 30
- Push-ups -- 10
- Crunches -- 10
Airmen who are physically unable to run may receive a medical waiver authorizing them to participate in an alternative aerobic fitness assessment. Available alternatives include cycle ergonometry and a 1-mile walk. Choice of an alternative test rests with the unit commander, based upon medical guidance. 
The ratings for the AFFT are as follows
- Excellent-- 90 or above
- Good -- 75 to 89.9
- Fail -- below 75
Originally, Airmen who scored below 70 on the AFFT failed, and those who scored between 70 and 74.9 received a marginal rating, while Airmen who scored above 75 passed.  In its current state, a score below 75 is considered failing, and Airmen are required to retest within 90 days. The test is now either pass or fail.
The aerobic portion of the AFFT consists of a 1.5 mile run.
The Air Force is the only branch that currently incorporates a body composition assessment into their PFT. It consists of a standard waist measurement.
The push-up portion of the AFFT requires that airmen perform as many correct push-ups as possible in one minute.
The push-up portion of the AFFT requires that airmen perform as many correct crunches as possible in one minute.
