Founding the Advanced Peer Fitness Leader Course; the coach behind the culture Aug. 27, 2026

For some Airmen, physical fitness comes naturally. They know how to work out, push themselves and prepare for the U.S. Air Force Physical Fitness Assessment. 

For others, walking into a gym can be intimidating. They may not know how to structure a workout, work through an injury or even where to begin. Yet, physical fitness remains an essential part of Air Force readiness and culture.

The Advanced Peer Fitness Leader course aims to close that gap by giving Airmen the knowledge and skills to lead their peers through safe, effective and inclusive physical training. The course grew from an effort to provide Peer Fitness Leaders with more education than the traditional training used to prepare them in order to lead physical training sessions.

U.S. Air Force Master Sgt. Martin Miller, 31st Fighter Wing Plans and Programs Office, Chief Innovation Officer, who has a degree in exercise science, professional certifications and more than 15 years of coaching experience, first developed the course in 2020 at Travis Air Force Base, California.

“A lot of PFLs were being ‘voluntold’ by their supervisors that since they have really good PT scores, they should be PFLs,” Miller said. “But they don't really understand how to teach other people, especially people that struggle in certain areas or have some kind of limitation.”

Instead of treating those differences as obstacles, the course teaches PFLs to recognize them and adapt. Students learn how to develop fitness programs, understand exercise science, prevent injuries, lead physical training sessions, mentor peers and modify exercises for people with different abilities and limitations. The course also incorporates hands-on training, allowing students to apply the concepts they learn.

The role of a PFL extends beyond counting repetitions or leading a warm-up. They become someone an Airman can turn to when they do not know where to start. The goal is not to make every Airman train the same way, but to help Airmen become more capable of taking ownership of their own fitness.

Miller said the course has evolved through feedback from the people taking it. The current version is designed to provide the information PFLs need while remaining accessible to Airmen with different levels of fitness knowledge.

“What we ended up with is a course as detailed as possible, but still simple. Anyone should be able to attend and understand the material without overwhelming them too much,” Miller said.

Rather than measuring success solely by how many Airmen achieve a perfect fitness score, the course emphasises education, consistency and finding sustainable ways to stay active.

“We’re not training people to run marathons,” said Miller. “We’re simply providing general physical fitness education to keep people healthy, in good shape and able to pass their PFA twice a year without any problems.”

As PFLs take that knowledge back to their units, the course has the potential to influence more than the next fitness assessment. It gives Airmen the tools to help their peers train smarter, stay involved and build confidence in their own ability to become fit.

Ultimately, the course is not just about teaching Airmen how to lead a workout. It is about teaching them how to help other Airmen succeed.
