About Sit Up Test Score Calculator

The one-minute sit-up test scores trunk flexor endurance against age norms of about 41 reps for men and 34 for women in their mid-twenties, declining roughly 0.45 a year. Forty reps at 30 is about 107% of norm. Many organisations have replaced it with the plank, because repeated spinal flexion under load is a questionable loading pattern.

Formulas

Age-adjusted norm

expected = base - 0.45 x (age - 25)

Score

percentage = reps / expected x 100

Worked example

Assumptions and limits

  • The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
  • This is an estimate from population-average equations, not a medical or diagnostic assessment. Individual results vary with genetics, training history and technique. Seek advice from a qualified coach or clinician before making significant changes to training.
  • This is an estimate for general information and not professional medical advice. See the full disclaimer for the limits that apply to this kind of calculator.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Why are sit-ups falling out of favour?

Repeated loaded spinal flexion is associated with disc stress, so plank and dead bug variants are now preferred for trunk endurance testing.

Do bent knees matter?

Yes. Knees at 90 degrees with feet held is the standard protocol; straight legs shift work to the hip flexors and inflate counts.
