Editorial policy: review, sources, and corrections

How our content is reviewed

A certified coach reviews every guide and post in English before it is published, and each one carries the line “Reviewed by a certified coach”. The coach reads the whole text, checks its advice against its sources, and approves it or asks for changes. No guide or post goes live without that approval, and any later change, even a small fix, is approved again before it appears.

Before a post goes to the coach, we check that it:

• answers its question in the first two or three sentences, with no filler opening;
• adds something of its own, such as a table or a worked example in both units, a rule you can apply, or a plain summary of a current position stand;
• links its claims to their sources and lists the sources at the end;
• says plainly when a medical condition changes the advice;
• makes no claim the research does not support.

Each post also carries a coach’s note: two to four sentences from the coach, set apart as a quote.

Guides and posts are also published in Spanish (Latin America), Portuguese (Brazil), German, French, Japanese, and Italian. A translation is published only after a check confirms that it says the same as the English text the coach approved and that it reads naturally in its language.

How we choose topics

Our guides and posts are for people who train. They cover strength training, technique, workouts, equipment, new research, nutrition, and recipes, and a post on research, nutrition, or food says how its subject serves your training. We spread posts across these subjects instead of repeating the same advice, and as people find this site, the questions they search for help us decide what to cover next.

Each question gets one page in each language. When new evidence touches a question we already answer, we update that page instead of publishing another.

Evidence and sources

When we explain what the research says, we give weight to evidence in this order:

1. Position stands, in which an expert body sums up the research on a question.
2. Systematic reviews and meta-analyses, which bring together the results of many studies.
3. Single trials, which show what one study found.

We do not let a single trial outweigh a review of many studies.

Source links go only to a short list of sites that we check before adding one: published papers through their DOI (the permanent link of a scientific paper), the research databases of the US National Library of Medicine, and the sites of public agencies for health, nutrition, and food.

A guide or post lists the sources it relies on at the end, each with its title, publisher, and year, and a link. Every post that reports a study or gives nutrition guidance has this list, and every language version shows the same sources under their original titles.

How we show numbers and units

In our guides and posts, every load and body weight appears in both kilograms and pounds, and food weights, liquids, oven temperatures, and amounts per body weight, such as grams of protein per kilogram of body weight, appear in both metric and US units. English pages show the US unit first, and pages in the other languages show the metric unit first.

Dates and numbers follow the style of the page’s language. When your browser uses the same language, dates, numbers, and the order of the units follow your region instead. Energy is given in kilocalories, and protein, carbohydrate, and fat in grams. Those units are the same in every region we publish for.

How we correct and update a page

When a newer study or guidance changes what a guide or post says, we update it: the coach approves the new text, each translation is updated and checked again, and the page shows its new updated date. A post shows the date it was first published and the date it was last updated, and a guide shows the date it was last updated. A small fix, such as a typo, is approved again too but keeps the date, so the updated date moves only when what the page says changes.

If you find a mistake, write to support@fittune.app and tell us which page it is on.

No sponsored content or affiliate links

Our guides and posts carry no sponsored content and no affiliate links. No company pays us to publish a post or to mention its products, and no link on this site earns us a commission. We make the FitTune app, and our pages tell you about it. Our About page says who we are.
