Fit to fight

Jay Guldjord, a refueling boom operator assigned to the Air Force Reserve 18th Air Refueling Squadron, 931st Air Refueling Group, McConnell Air Force Base, Kan., strains to complete a set of high repetition dumbbell curls during a group workout at the base fitness center, Feb. 4, 2015.
