YOUNGSTOWN AIR RESERVE STATION, Ohio -- Air Force Reserve Tech. Sgt. Jerry Killian, a 910th aerospace maintenance technician and an ART, runs on a treadmill at the base Fitness Center each day after work here. He said although he doesn't really enjoy running, regular treadmill interval workouts and distance runs along with changes in diet helped him lose 33 pounds and whittle four inches off his waist since last summer.
