The US Army has a strong focus on low-intensity cardio-respiratory and muscular fitness.
Since I understand that there are many fitness buzzwords out there, allow me to define these two.
In this context “intensity” refers to the relationship of work performed to the maximum capacity of
that “system”, cardio-respiratory or muscular. In this context, low-intensity cardio-respiratory work
capacity would be similar to the normal Army 4-mile unit run while high-intensity cardio would be
more like a 40m prowler push; low-intensity muscular fitness would be like normal Army push ups
while high-intensity muscular strength would be like a 1RM bench press.
In order to prove that the US Army culture is low-intensity-focused one only need observe
a week in the life of a Soldier from the hours of 0630 to 0730 all over the world. During this single
daily hour of physical training most Soldiers are relegated to 3-5 mile runs and sit-up and push-up
improvement programs. Semi-annually soldiers must pass the Army Physical Fitness Test (APFT)
consisting of 2 minutes of pushups, 2 minutes of sit ups, followed by a 2-mile run on a flat road or
track. Each soldier gets 10 minutes to rest between events but must complete the APFT in less than 1
hour. See table 1 for passing and maximum performance standards by age and gender. The minimum
standards are disappointing while the maximum standards are quite achievable.
