BYI EDITORIAL / UPDATED 25 SEPTEMBER 2026
Useful advice.
Clear limits.
The Training Journal is published by Begin Your Impossible, Rob Francis’s fitness brand. Here is how to read it—and what it does not claim to be.
Who creates these guides
BYI Editorial is the label for this site’s editorial content, not a named trainer or a professional credential. This initial collection was created using AI-assisted research, drafting and editing. Sources, examples and page presentation have been checked during production; this is not an independent professional review.
The articles do not claim that Rob personally wrote, tested or coached every recommendation. His personal story and experience are separate from the research summaries in these guides.
What the sources do—and do not—show
Articles link to relevant research papers and official guidance. Links beside a section identify its evidence or context; the full source list is at the end. Research findings have boundaries, including the participants, training methods and study duration. A result in a study is not a guaranteed outcome for you.
Worked examples, fictional training logs and decision checklists explain how to think about a problem. They are editorial illustrations, not clinical protocols or evidence that a BYI product produces a particular result. Dates identify the content update, not a promise of ongoing monitoring.
Who the content is for
These guides are general education for adults 18 and older. They do not diagnose symptoms, clear you to exercise, rehabilitate an injury or prescribe individualized meals. Seek qualified support for unfamiliar equipment, technique questions, health concerns or restrictions. Weight-loss content is not an appropriate starting point for minors or people with pregnancy, breastfeeding, underweight or eating-disorder concerns without clinical guidance.
Our commercial relationship
BYI sells training resources, so some guides link to our products or free kit. Reading an article does not require signing up or buying anything. A kit request unlocks a PDF; it does not automatically subscribe you to promotional email. Rob’s IM8 affiliate partnership is disclosed on the separate offer page. These articles are not evidence for supplement claims.
Corrections and feedback
Found an error or a source that does not support the text? Send the article address, the specific passage and your suggested correction to @beginyourimpossible. Do not send medical records or private health information. Substantive corrections should update the affected text and its date; an unresolved safety concern should keep an article out of promotion.
