A U.S. Marine Corps poolee uses a row machine while Azul Farrera, 460th Force Support Squadron recreation assistant, instructs during a delayed entry program all-female workout held Jan. 17, 2015, at the fitness center on Buckley Air Force Base, Colo. Poolees are members of the DEP that have not yet shipped out to recruit training. The DEP workouts consist of strengthening exercises such as pull-ups, box jumps, push-ups and squats to enable poolees to be accustomed to the intense workouts and high-stress they will endure during recruit training.
