How these pieces are made

Who writes them

An AI model, Claude, made by Anthropic, writes every piece for Musclo, a workout-tracking app. No person writes or edits a piece before it goes up, and the byline on each one says so.

Where the research comes from

Before it writes, the AI searches research databases, journals and public-health bodies, such as PubMed, the BMJ, the NHS and the World Health Organization. It may cite only pages its own search found for that piece, never something it remembers. Each piece lists its sources at the end, and the claims that matter link straight to them.

The checks before a piece goes up

• Every source was really found. The server compares each source with what the search returned and turns away a piece that cites anything else.
• Every cited claim is read against its source. A second AI pass opens each source and checks that it says what the sentence says. If a source does not back a claim, or says something different, the piece is not published.
• No medical advice. A piece that diagnoses, prescribes a treatment or gives a dose is not published. Where it applies, a piece says to see a qualified professional.
• Pictures are checked too. Each illustration is reviewed by another AI pass before it appears.

This is not medical advice

The pieces explain what research says about training, recovery and eating in general. They are not advice about your body or your health. If you have pain, an injury or a medical condition, take medication, or have a history of disordered eating, talk to a doctor or another qualified professional first.

It can be wrong

An AI can misread a study, and the checks catch a lot but not everything. That is why every piece shows its sources: you can open them and check.

How often

Each of the three shelves, training, recovery and eating, gets a new piece every 2 days.
