Sit-Ups in the Armies of the World

Armies have always needed a cheap, fast way to answer one question: is this recruit fit enough? The sit-up became a favorite answer. It requires no equipment, works in a field or a barracks, and gives a clean number you can compare against a standard. For much of the twentieth century, timed sit-ups were a fixture of military fitness testing across the globe, prized because they gauge core endurance while asking nothing more than a patch of ground and a stopwatch.

The United States built the sit-up into its long-running fitness test, where soldiers knocked out as many clean reps as they could inside a set time limit. That changed with the shift toward the Army Combat Fitness Test, a more rounded battery meant to measure strength, power, and endurance across several events rather than leaning so heavily on one movement. The classic sit-up lost its starring role in the formal test, but core work never left the daily training floor. Nobody in uniform stopped caring about a strong trunk; they just stopped treating a single exercise as the whole measure.

Other forces tell similar stories with local accents. British Army physical training has long used sit-ups to build stamina, with pass standards scaled by factors such as age so that different soldiers are held to appropriate, achievable marks. India's armed forces, among the largest anywhere, lean on physical proficiency testing to judge readiness, and abdominal work sits comfortably alongside a broader emphasis that in recent years has also folded in yoga as a route to a stable, resilient core.

The pattern repeats wherever you look. Russian military training carries a reputation for intensity, with core conditioning baked into daily routine rather than saved for test day. China's People's Liberation Army likewise uses physical assessments to check the abdominal strength and endurance of its personnel, treating a strong midsection as basic soldierly equipment rather than a nice-to-have.

What unites all of them is not the exact rep count or the precise standard, which shifts from country to country and decade to decade. It is the underlying logic. A soldier carries loads, absorbs impacts, and has to stay steady when tired, and a well-conditioned core supports all of that. The sit-up earned its place in military life by being simple, portable, and honest about what it measured, and even as formal tests evolve, the priority behind it has barely moved.
