Who is responsible
Articles credited to Gainz Editorial are produced and maintained by the Gainz product and editorial team. We do not attach invented expert credentials or imply medical review where none occurred.
Our aim is to make established training principles understandable and usable. Our content is educational, not individualized medical care, diagnosis, rehabilitation, or a substitute for a qualified professional.
How we choose sources
We prefer sources that readers can inspect directly. The best available source depends on the claim.
- Systematic reviews, meta-analyses, consensus statements, and position stands from recognized scientific or professional bodies.
- Peer-reviewed primary research when broader synthesis is unavailable or a specific result needs support.
- Official documentation and first-party product sources for app features, prices, policies, and platform requirements.
- High-quality secondary explanations only when they add context and do not replace the underlying evidence.
We avoid citation laundering, unsupported numerical precision, and references that do not actually support the nearby claim. Where evidence is mixed, early, or population-specific, we say so.
Our review process
1. Define the question
Each guide starts with a concrete decision a lifter may need to make, such as selecting volume, progressing load, or recognizing when fatigue calls for restraint.
2. Separate evidence from interpretation
We distinguish what a source found from the practical recommendation Gainz draws from it. A reasonable coaching interpretation is not presented as a universal scientific fact.
3. Check safety and scope
Injury, health, nutrition, recovery, and supplement content receives extra scrutiny for contraindications, uncertainty, and language that could encourage unsafe self-treatment.
4. Verify the page
Before publication or a material update, we check the title, visible byline, dates, links, claims, structured data, and product calls to action for consistency.
Updates and freshness
Publication dates describe when a guide first appeared. A modified date changes only after a meaningful editorial revision—not because a sitemap was regenerated. Product comparisons and time-sensitive feature claims should include a last-checked date and be revisited when the underlying products change.
Minor spelling or formatting corrections may not change the visible modified date. Material changes to advice, conclusions, sourcing, or product facts do.
Commercial and comparison disclosure
Gainz publishes gainz-pro.com and benefits when a reader downloads or subscribes to Gainz. App Store links are direct product links, not third-party affiliate links.
Competitor comparisons should use neutral language, identify the facts checked, link to primary product sources where possible, and explain that Gainz is the maker of the product being recommended. We do not fabricate reviews, ratings, user quotes, or transformation claims.
Use of AI tools
AI tools may assist with research organization, outline exploration, accessibility checks, or copyediting. They are not accepted as a source. A human is responsible for the published page, checking cited material, product facts, links, and final wording. We do not knowingly publish invented citations or unverified AI summaries.
Corrections and feedback
If you spot an inaccurate claim, broken source, missing disclosure, or accessibility problem, email support@gainz-pro.com or use our contact form. Include the page URL and the sentence in question. We review corrections and update material issues as quickly as practical.
For health or safety concerns, read the health disclaimer. Stop training and seek qualified care for severe pain, injury, or urgent symptoms.
