Check the source, not the argument, when a client's video contradicts you. Level 2/3 already taught you how

The short version

A client arrives with a video, a screenshot, or a friend's story that says the opposite of what you told her last week. The instinct is to defend the point. The better move is the one Level 2/3 already trained into you, check the source, not your pride. FOCUS names identifying credible evidence-based sources as a stand-alone skill, exactly so that moment has a method attached to it instead of a debate.

Key Takeaways

• Criterion 6.1 of T/617/8569 asks a trainer to identify credible evidence-based sources of guidelines on programme design and safe exercise.
• The industry runs on a small set of named fallacies, call to authority, call to history, call to region, call to nature, worth knowing by name so they're easy to spot.
• FASTER Sports Scientist takes the same checking skill further, one to one, to degree level.

What the unit asks

Criterion 6.1 asks you to identify credible evidence-based sources of guidelines on programme design and safe exercise. It sits inside "Planning and delivering personal training programmes," which is a fair place for it, because the moment this skill gets used is rarely a quiet afternoon of reading. It's a client, mid-conversation, holding up her phone.

The FOCUS unit doesn't ask you to referee every claim on the internet. It asks for a working method: where the claim came from, whether that source has any standing, and whether it fits the person you're training rather than the person in the video.

Naming the fallacy makes it smaller

The reason a bad claim spreads is usually one of a handful of moves, and once you can name them they stop feeling like arguments and start looking like habits. Call to authority, someone famous said it. Call to history, it's how training used to be done, so it must be right. Call to region, the Bulgarian did it this way. Call to nature, an animal moves like this, so a person should too. None of them are evidence. All of them are common enough in the industry to be worth spotting on sight, in someone else's claim and occasionally in your own.

That's the whole trick. You're not arguing the client out of a video. You're showing her, calmly, which kind of claim it is.

What to do next

The Certified PT route builds this checking skill inside the full Level 2/3 qualification, taught so it's a habit by the time you need it live, not a fact half-remembered from a slide. FASTER Sports Scientist takes the same skill to degree level, one to one, for a trainer who wants to go further than naming a source, and go and find the evidence themselves.
