The Royal Canadian Air Force Exercise Plans are two exercise plans developed for the Royal Canadian Air Force (RCAF) by Dr. Bill Orban in the late 1950s, first published in 1961. The 5BX plan (Five Basic Exercises) was developed for men; a corresponding program was developed for women under the name XBX (Ten Basic Exercises) and the two plans were subsequently published together as one book. The popularity of the programs in many countries around the world helped to launch modern fitness culture.
