Members of the 307th RED HORSE and 307th Civil Engineer Squadron prepare ground for two of three additional fitness areas being built along a running trail on Barksdale Air Force Base, La., Sept. 8, 2014. Exercise equipment to be installed on the pads have smart phone capabilities, and will allow the athlete an opportunity to watch videos on how to properly use each piece of equipment and several examples of different exercises.
