Attaining the fitness required to join the Air Force is well within most people's capability. Being paid to stay fit and healthy is one of the benefits of joining.
What about weight?
The maximum allowable Body Mass Index (BMI) for entry to the Air Force is 32.9 (29.9 for Pilots). BMIs of less than 18.5 are considered too low as they present a risk of injury during training. Your BMI will be measured before you can join, so check it well in advance and take any actions necessary.
The ADF Active mobile app will help you determine if you're fit enough to serve, then guides you to the fitness level required to join the Air Force. Alternatively you can follow our 4-week Fitness Plan.
