How the guides are researched, written, and corrected.

The guides are written and maintained by Felipe Passos, the founder of Corpus, who has been strength training for about ten years. He is not a physician, dietitian, or certified coach, and no article claims otherwise.

There is currently no clinically credentialed reviewer. That's why we don't publish content that depends on clinical judgment — medication dosing, diagnosis, or treatment — and the articles stay within measurement, interpretation, and progress tracking.

In order of preference: systematic reviews and meta-analyses, controlled trials and validation studies, then position statements from scientific bodies. Regional research (for example, Brazilian studies on SciELO) is used when it covers the population or context in question.

Every article lists at least three sources, and every specific number in the text should trace back to one of them. Where evidence is weak, small, or conflicting, the text says so instead of rounding it up to a confident conclusion.

Invented or rounded-up statistics, fake testimonials or reviews, before-and-afters presented as typical results, and outcome promises. Corpus's own numbers only appear alongside a description of how they were collected — see the methodology.

We use AI tools to help find studies, structure drafts, and edit for clarity. They are not a source of facts: every claim is checked against the cited source, and the author reviews and is accountable for every published page.

Articles mention Corpus when it's relevant to the question — a conflict of interest we disclose on every article. In comparisons with other apps or methods, we say that we make Corpus, describe competitors based on what they publish, date the comparison, and include the places where other options are the better choice.

Every article shows when it was last reviewed. Articles are re-reviewed when relevant research appears, when the product changes, or when someone reports an error. Corrections that change the meaning of a claim are noted on the article itself.

Photo-based estimates, calculators, and recovery metrics are directional signals for following a trend. They don't replace a clinical exam, a DEXA scan, or an assessment by a health professional.
