How we write
articles.

Every article starts from published research: peer-reviewed studies, meta-analyses that combine many studies, and position statements from bodies like the American College of Sports Medicine. Where there is a meta-analysis, it carries more weight than a single study.

Articles are researched and drafted with the help of AI tools.

AI tools can invent citations that look real, so no source is taken on trust:

• Each study is looked up in PubMed, the US National Library of Medicine's database, or in the journal itself.
• Its title, authors, journal and year are confirmed, and the article links to that record.
• Numbers quoted in an article come from the study itself, not from news stories or other blogs.
• A claim the source does not support is rewritten or removed.

Every factual claim from research carries a numbered citation that jumps to its source at the end of the article. Every study we cite is also listed in the research library.

When studies disagree, the article says so. When the evidence is a few small studies, the article says that too. When a finding comes from an observational study, which shows that two things go together rather than that one causes the other, the article points it out.

We would rather give you an honest "it depends" than a confident answer the research does not back.

Articles reviewed by a qualified professional, such as a certified strength and conditioning specialist or a physical therapist, show the reviewer's name, credentials and the date of the review under the title. An article without that line has not had an expert review yet.

The date under each title is when the article last changed in substance: new research, a correction, or a review. Small fixes like typos do not change it.

Found a mistake, or a study we should know about? Email support@manifest-performance.com. We check every report against the source and correct the article when it is wrong.

No article is sponsored, and articles contain no affiliate links. When an article mentions one of our programs, it is because the program puts that article's advice into practice.

Articles are general fitness information for healthy adults. If you have an injury, a medical condition, are pregnant, or are returning after a long break, check with a doctor or physical therapist first. See also how programs are made.
