Matthew Gruse, exercise physiologist for the 910th Airlift Wing, puts tape on the gym floor marking the start line for a beep test here, April 18, 2019. The 910th AW is doing a trial run of the beep test, which requires Airmen to repeatedly run a short distance at increasing paces marked by a series of beeps played through a speaker, as a potential alternative to the 1.5 mile run portion of the Air Force fitness assessment.
