Editorial Principles

The Performance Lab publishes content when it helps people better understand training, nutrition, recovery or gymwear.

We do not write to reach the highest possible number of pages. We write when a topic offers clear value and can be explained carefully.

Fitness and health can rarely be explained in absolute terms. That is why we distinguish between established fundamentals, practical recommendations, estimates and open questions.

Where context is necessary, we provide it. Where a method has limitations, we name them.

We prefer primary literature, systematic reviews, recognised professional bodies and official institutions. We do not invent sources, and we do not adopt a claim simply because it is repeated often.

Every calculator states its underlying method, key assumptions and known limitations. Results are presented as guidance, not as a diagnosis or a guarantee.

When we find an error or can improve an explanation, we revise the page. Substantial changes may be documented in a version history.

Body Supremacy funds the Performance Lab through premium gymwear. Content, calculators and planners are not written to push users towards a purchase.

We are visible as a brand: the navigation and the footer link to the Body Supremacy shop on every page. That is standard site navigation, not an editorial recommendation.

Within content, product recommendations appear only where they fit the topic — for example in articles about gymwear materials or the history of the brand. In health, training and nutrition content, and in calculators and planners, we do not interrupt an explanation with a product recommendation.
