Never settle: back 2 basics and instructor strive for excellence
A Back 2 Basics class led by U.S. Air Force Staff Sgt. Cristina Sullivan, 633rd Force Support Squadron B2B lead instructor, prepares to dismiss at Shellbank Fitness Center at Langley Air Force Base, Va., Jan. 8, 2015. B2B is designed to improve an Airman in all three areas of their Air Force physical fitness assessment-body composition, aerobic and muscular fitness components- not only with workouts, but with nutrition education and habit-change as well.
