Prince Philip was sprightly and walked without a stick until he died in April at the age of 99. What kept him going? It was probably 5BX, the original functional fitness Routine.

“[It] was designed to show you how to develop and maintain high levels of physical fitness no matter where you are, ”it says the introductory brochure To the training. “The 5BX plan makes physical fitness achievable for every member of the RCAF.”

Developed by Canadian Bill Orban the routine based on research he conducted at the University of Illinois in the 1950s. By testing oxygen uptake, he found that exercise duration was less important than intensity to overall fitness. The RCAF knew that their personnel were incapable of combat, and tasked Orban with developing a training program that troops could conduct anywhere, in fact in their barracks, and was short enough to do every day.

“To develop physical fitness, exercises must be balanced and planned,” explains the spokesman in a 5BX commercial. “You have to be progressive. And above all vigorous and regular. “

The five basic exercises include tiptoe, situps, back extensions, pushups, and running. To make it accessible and encourage continuous intensification, Orban added six diagrams that dictate the modification of each exercise and the progression of the rep count. As the demands on fitness, strength, and endurance increase, the time spent on each exercise, and the total length of the workout, does not. For example, on Chart One, the sit-up is done with your legs flat and requires you to “lift your head just high enough to see your heels”. A “D” value is 3 repetitions in 1 minute; an “A” is 18. On Chart Six, the toughest, there are 35 to 50 V-seats in 1 minute.

The 11-minute duration and device-free nature of the exercise were both controversial at the time, but RCAF testing confirmed its effectiveness. Orban then developed a women-specific version called the XBX that included six trains in 12 minutes. And 5BX became popular inside and outside the military.
