What is leg tuck (Army combat fitness test)?

The Army Combat Fitness Test is the evaluation of the physical domain of the Army’s Holistic Health and Fitness System. An age and gender performance-normed scoring scale will be used to assess a Soldier’s physical fitness as part of a general physical fitness exam.

The Army Combat Leg Tuck Test is an evaluation of a soldier’s ability to tuck their legs behind their back while in a prone position. The test is used to determine if a soldier is fit for duty in the infantry or armored forces. 

The Army Combat Leg Tuck Test is a medical evaluation to determine if a soldier has leg weakness that would make them unable to complete certain physical tasks, including walking and standing. The test is also used to help determine if a soldier has an ankle or foot injury.

Why leg tuck so hard?

But we can all agree that Leg Tucks have proved challenging, particularly for women. For the same reason why leg tucks are difficult for me (a guy, FYI), women have less mid-scapular muscular strength and endurance. Males and females naturally have different amounts of muscle.

Leg tucks are difficult to perform. It’s not like doing pull-ups and knee-ups separately; with leg tucks, you have to work practically every muscle in your body at each rep, which can be exhausting. 

Not to mention that most people who claim to be able to perform chin-ups or pull-ups frequently do not return to the proper hanging position after each rep, which means that if the person scoring your leg tucks is rigorous, you may end up with a big fat zero for the exercise.

What is APFT?

The older Army physical fitness test (APFT), which dates back to the early 1980s and consisted of push-ups, sit-ups, and a two-mile run, will be replaced with the new Army combat fitness test (ACFT).

Army Cobalt fitness test events

Army cobalt fitness test events consist of

  • 3 repetition maximum deadlift (MDL)
  • Standing power throw (SPT)
  • Hand release push-up (HRP)
  • Sprint-drag-carry (SDC)
  • Plank (PLK)
  • Two-mile run (2MR)


Deadlift the maximum amount of weight three times.

The lower body, grip, and core physical strength of a Soldier are all measured by the MDL in order to evaluate their muscular strength. It necessitates strong back and leg muscles and protects soldiers’ hips, knees, and lower backs. Balance and flexibility are ancillary fitness-related factors that the MDL evaluates.


The distance can be gained by throwing a 10-pound medicine ball backward and overhead.

The SPT event measures a Soldier’s ability to generate rapid, explosive movements with their upper and lower body to test the Power component of fitness. Balance, coordination, and flexibility are secondary fitness components assessed by the SPT.


Perform as many Hand-Release Push-ups as you can in two minutes.

The HRP measures a soldier’s upper body endurance in order to evaluate their muscular endurance level. Training your upper body and core strength benefits greatly from the HRP. Flexibility is a secondary aspect of fitness that the HRP measures.


Run 5 times for 50 meters in the following order: sprint, drag, lateral, carry, and sprint.

The SDC uses a Soldier’s ability to sustain moderate to high levels of physical exertion for a brief amount of time to assess their anaerobic power, anaerobic endurance, and muscular endurance components of fitness. The SDC also measures additional fitness indicators like reaction time, flexibility, agility, balance, and coordination.


As long as you can, hold the proper plank position.

The PLK measures a Soldier’s core strength and endurance to assess the Muscular Endurance component of fitness. The PLK assesses balance as a supplementary component of fitness.


Run two miles on a timed, largely level outdoor course.

The 2MR analyzes the fitness element of aerobic endurance. When performing repetitive physical duties, a Soldier with greater aerobic endurance can work longer and recover more rapidly.
