Col. Bill Routt, U.S. Air Forces in Europe Director of Safety, prepares to begin his timed workout of the day at the Ramstein Air Base Northside Fitness Center Feb. 14, 2009. The idea behind CrossFit Ramstein is to challenge a person's strengths and weaknesses and to improve their total human performance. CrossFit focuses on 10 fitness domains: cardiovascular/respiratory endurance, stamina, strength, flexibility, power, speed, agility, balance, coordination and accuracy.
