Sit-Up Test Norm Calculator

About this calculator

The one-minute sit-up test counts how many full sit-ups you complete with correct form in 60 seconds, a standard field measure of abdominal muscular endurance used across fitness testing batteries for decades. Because it’s a timed, repeated-rep test rather than a hold, it captures a slightly different quality than a plank — endurance under repeated dynamic contraction rather than sustained isometric hold.

Military, law-enforcement and school fitness tests, and general fitness assessments, use the one-minute sit-up count because it needs no equipment and takes only a minute to administer, while published normative tables convert the raw count into a percentile against age- and sex-matched adults so an individual score can be judged against a meaningful benchmark rather than in isolation.

This calculator takes your one-minute sit-up count and returns your core-endurance percentile against standard adult norms.
