Mariposas
Editorial Policy
We aim to be one of the most accurate, least hype-driven fitness resources on the web. Here's how we work.
Facts come from data, not guesses
The factual content on every page, muscles worked, MET values, sets/reps, paces, calorie math, is rendered directly from our structured datasets and from the published sources on our references page. We do not invent statistics or fabricate research findings.
AI assistance, human review
We use AI assistance to draft the explanatory prose that surrounds our data, then the Mariposas team reviews it for accuracy and tone. The underlying numbers are never generated by AI, they are inserted from our data.
Honest authorship
Articles are published by the Mariposas team. We do not invent fake author personas or claim professional credentials (e.g., "MD", "RD") that we do not hold. Where appropriate we cite the exercise-science literature rather than appeal to false authority.
Corrections
Found an error? Tell us and we will fix it and note the update. Pages show a "last updated" date.
Independence
Our tools and guides exist to be genuinely useful. The only thing we promote is our own free app, clearly labeled.
