Two names sit behind this site. One drafts the guides you're reading, the other owns ExerciseCalc and holds the line on the formulas. Below is what each of them is actually responsible for.
Naomi Foster
Contributing Writer, Health & Wellness
Naomi writes the running and training guides on ExerciseCalc, along with related fitness and nutrition content on a few other sites in the Encore Editorial network. Her job is to take a calculator's output, pace, calorie burn, heart-rate zones, VO2 max, and explain what the number means and where the underlying method came from, in plain language a reader can act on without a sports-science background.
Her byline is on Good Running Pace by Age, How Many Calories Do You Burn Running?, How to Calculate Running Pace, How to Train for a 5K as a Beginner, the marathon pace chart, What Is a Good 5K Time?, and the running and training guide.
Before a guide of hers goes up: every figure she cites, a MET value, an age-graded pace benchmark, a heart-rate formula, gets traced back to the primary source named in the piece rather than copied from a secondary roundup, and the date it was last checked is noted. Naomi is not a coach, a trainer, or a clinician, and nothing she writes is presented as personalized advice; it is a plain-language walk-through of a published method with the source attached.
Chris Terry
Owner and Editor, Encore Promotional Products
Chris owns and operates ExerciseCalc through Encore Promotional Products, alongside a small group of other free calculator sites in the Encore Editorial network. He built the pace, calorie, heart-rate and VO2 max tools on this site and reviews every guide Naomi files before it publishes, checking her cited formulas against the same sources named on the editorial standards page.
What he checks: that the pace and split math on every calculator matches simple time-over-distance arithmetic with no rounding tricks hidden in the code; that the MET values behind the calorie tools trace to the published Compendium of Physical Activities rather than a guessed average; that the Race Time Predictor's exponent matches Riegel's original 1977 formula; and that the heart-rate and VO2 max calculators clearly label which method (age-estimate, Karvonen, or the Cooper test) produced a given number, since none of these are exact for every individual body.
