AI chatbots answer fitness questions using the pages they retrieve about a brand's products, and U.S. adults already ask them. Pew Research Center found that 49% of U.S. adults use AI chatbots and that 40% of those users ask them for diet and fitness information. Fitness brand PR now includes checking what those answers say about a product's specifications and claims.
How many people ask AI chatbots about fitness?
About one in five U.S. adults asks an AI chatbot for diet and fitness information. Pew's February 2026 survey of 5,119 U.S. adults found that 49% use chatbots and that 40% of chatbot users ask them for diet and fitness information, which works out to 20% of all adults.
Wearables put fitness data in the same hands. The same Pew survey found that 37% of U.S. adults own a smartwatch, so a large share of gear shoppers already track workouts and may ask a chatbot what to do with the numbers.
Which assistants should a fitness brand check first?
A fitness brand should check ChatGPT, Gemini, Microsoft Copilot and Meta AI first, because Pew found those are the most used chatbots among U.S. adults. ChatGPT leads at 44%, followed by Gemini at 24%, Copilot at 17% and Meta AI at 14%.
Claude, Grok and Character.ai each reach about one in ten adults or fewer, so they come second in a first pass. Perplexity was not part of Pew's list, but it belongs in the check because shoppers use it for product research.
What do gear shoppers ask AI?
Gear questions fall into four types: fit and space, goals, cost and value, and safety and claims. The prompts below are illustrations of each type, not survey data, and the right column lists what a brand's own pages need to state for an assistant to answer correctly.
| Question type | Illustrative prompt | What the brand page needs |
|---|---|---|
| Fit and space | Which adjustable dumbbells fit a small apartment? | Dimensions, weight range, floor space, noise level |
| Goals | Which treadmill suits walking five miles a day? | Intended use, user weight limit, deck size, motor rating |
| Cost and value | Is a connected bike worth the monthly fee? | Price, subscription terms, warranty, return policy |
| Safety and claims | Is this protein powder safe to take daily? | Ingredient list, third-party test results, cited evidence |
A missing detail is the usual failure. If the page does not state the weight limit, an assistant either skips the product or repeats a figure from a retailer listing or a review.
Which fitness claims need a source before AI repeats them?
Claims about results, safety and health need a named independent source on the page, because an assistant repeats whatever the retrieved page states. Accuracy is the concern people raise most about these tools: among U.S. adults who do not use chatbots, 45% say distrust of the information's accuracy is a major reason, per Pew.
Product pages should avoid promising medical outcomes and should link each performance claim to a test, study or standard. Brands selling supplements can start with supplement marketing claims rules from the FDA and FTC.
How should a fitness brand check what AI says?
Ask the same 10 to 20 shopper questions in each assistant and record what each answer says about your products and your competitors. Write the questions by type from the table above, using real product names.
- Record whether each product is named, and in what order.
- Record every wrong specification, price or claim.
- Record which pages each assistant cites for the answer.
Illustrative scenario: a home-gym brand finds that assistants list its bench with the wrong weight limit. The fix has three parts. Correct the specification on the product page, correct the retailer listings that repeat it, then send the corrected spec sheet to the reviewers who covered the bench.
Where does PR fit in fitness marketing?
PR puts corrected, tested facts into independent sources, which are the pages an assistant retrieves beyond the brand's own site. That work includes review outreach, holiday gift guide outreach strategies and the placement work behind digital PR services.
Creators matter here too, because shoppers see their reviews and assistants can retrieve them. 5W's research on how brands use AI to choose creators covers the other side of that relationship, and its Creators and AI Visibility research adds the visibility view.
For app brands, the Fitness and Wellness Apps AI Visibility Index covers fitness and wellness app brands in AI answers. The full 5W AI Visibility Index lists every category 5W has measured.
CONCLUSION
Fitness brand PR now means keeping product specifications and claims accurate on the pages AI assistants retrieve, and a brand that audits those answers this month can work with 5W on the fixes and the press placements behind them.
