Airmen perform callisthenic exercises as part of the newly implemented "PT Boot Camp" on Jan. 12, 2010, at Joint Base Lewis-McChord, Wash. If an Airman scores 74.99 or below on the PT test, they are required to attend the new fitness program. PT Boot Camp consists of a one-hour training session, five days a week, to include one non-duty day. (U.S. Air Force Photo/Airman Leah Young)
