How we write and check guides
- Every guide is checked against its sources and against the rules the app uses. Articles, programs and comparisons list their sources at the foot of the page.
- A program’s plan is copied from the app’s engine by a script, not typed in by hand. Each calculator is tested against the engine’s own cases.
- In a comparison, the other app’s facts are read on its own pages, and the page shows the day they were last checked.
- The date on a guide changes only when its words change.
- We do not publish sponsored guides or paid reviews.
- Found a mistake? Write to support@joinrigor.com and we will correct it.
Training guidance, not medical advice
RIGOR and its guides give general training guidance. They are not medical advice. If you have an injury or a health condition, ask a qualified professional before you train.
