Quick answer. Describe classes by format, intensity, length and what to bring, and have the AI flag any phrase that promises weight loss, pain relief or another health result. Share a client's progress only with written permission, in their own words, and if a post cites a specific result, add what clients generally achieve or drop the number. Keep intake forms, injuries and measurements out of the chat completely.
Why a workflow beats a one-off prompt
Fitness marketing leans on transformation language, and chat assistants have read plenty of it: "torch fat", "fix your back", "lose 10 pounds in 30 days". Those phrases are claims, and the FTC expects health claims to be backed by competent and reliable scientific evidence. The workflows let the AI do what it's good at, turning your schedule, offer terms and approved quotes into clean copy, while the prompts keep the promises out and the client data off the screen.
Each workflow has five parts: the job it does, a prompt template with [BRACKETS] to fill, an example input with the kind of output to expect, a check before you send (facts, numbers, names, tone), and a privacy rule. Every prompt ends by telling the AI to write [CHECK] instead of guessing, so missing facts show up instead of being invented.
Three workflows you can run today
1. Class descriptions with a health-claim check
Prompt template (replace every [BRACKET] with your facts):
You are writing class descriptions for a fitness studio's schedule. For each class below, write a 40 to 60 word description covering: format, intensity level [1 TO 5], who it's built for in terms of experience (beginner, all levels, advanced), what to bring, and how long it is. Don't promise weight loss, calories burned, injury recovery, pain relief or any medical benefit, and don't describe ideal bodies. Classes: [CLASS NAME, LENGTH, FORMAT, INTENSITY, EQUIPMENT] for each. After the descriptions, list any phrase in your draft that could be read as a health or results claim. If any fact you need is missing, write [CHECK] instead of guessing. After the draft, list every [CHECK] and anything you assumed.
Example input: Spin 45 (45 min, intervals on bikes, intensity 4, water and towel); Mobility Flow (30 min, floor-based, intensity 1, mat provided); Strength Circuit (50 min, dumbbells and kettlebells, intensity 3).
What to expect: Expect three short descriptions such as "Forty-five minutes of interval rides set to music. Intensity 4 of 5; bring water and a towel." and a short list of phrases to look at, like "melt fat" or "fix your back" if any crept in.
Check before you send:
- Facts: format, length and equipment match your schedule.
- Numbers: class lengths and intensity ratings right.
- Names: class and instructor names spelled as on your schedule.
- Tone: inviting, about the class, not about changing anyone's body; fix every flagged phrase.
Privacy rule: No member names or attendance data needed.
Rule to know: The FTC's Health Products Compliance Guidance says health-related claims need competent and reliable scientific evidence, and consumer testimonials are never enough on their own to back up claims about a health product's effects. (FTC)
2. Client results post with a typical-results check
Prompt template (replace every [BRACKET] with your facts):
Write a social post (under 120 words) celebrating a client's progress, using only what the client approved in writing: [WHAT THEY AGREED TO SHARE, IN THEIR WORDS]. Time frame [WEEKS/MONTHS]; what they did [SESSIONS PER WEEK, PROGRAM]. If the post mentions a specific result such as pounds lost or a time improved, add a clear line on what clients generally can expect: [GENERALLY EXPECTED RESULT FROM YOUR OWN RECORDS, OR REMOVE THE NUMBER]. If the client received anything free or discounted for sharing, say so in the post. No before-and-after body comparisons in the text, and no health claims. If any fact you need is missing, write [CHECK] instead of guessing. After the draft, list every [CHECK] and anything you assumed.
Example input: Client agreed to share: "I can deadlift my bodyweight now and I've stopped dreading Mondays." 6 months, 2 sessions a week; got one free session as a thank-you.
What to expect: Expect a short story built on the client's quote and the six-month, twice-weekly program, a line like "She received a complimentary session for sharing her story", and no weight or body comparisons.
Check before you send:
- Facts: every detail is something the client approved in writing.
- Numbers: any number is the client's; a typical-results line is added or the number comes out.
- Names: tag or name the client only if they asked you to.
- Tone: celebrates effort and strength, not appearance; disclosure is in the post itself.
Privacy rule: Never paste the client's measurements, weigh-ins, photos, injuries or health history. Type only the approved quote.
Rule to know: The FTC's Endorsement Guides Q&A says that if you can't show an endorser's results are what people generally achieve, the ad must clearly disclose the generally expected results. Gifts or discounts to the person sharing must be disclosed. (FTC, FTC)
3. Trial class follow-up sequence
Prompt template (replace every [BRACKET] with your facts):
Write three short messages for someone who took a trial class at our studio: (1) same-day thank-you under 50 words; (2) two-day check-in under 60 words asking how they felt and answering one common question [QUESTION AND OUR ANSWER]; (3) reminder under 70 words that our intro offer [OFFER, PRICE, WHAT'S INCLUDED, END DATE, CANCELLATION TERMS] ends soon. Use only these terms. No pressure, no comments about their body or fitness level, and no health promises. If any fact you need is missing, write [CHECK] instead of guessing. After the draft, list every [CHECK] and anything you assumed.
Example input: Intro offer: 3 classes for $39, use within 21 days, no auto-renew. Common question: "Is it OK that I couldn't keep up?" Answer: everyone modifies; instructors show options.
What to expect: Expect three messages with first-name merge fields: a thank-you, a check-in that says modifications are normal, and a reminder with the $39, 21-day, no auto-renew terms stated exactly.
Check before you send:
- Facts: offer terms match what's posted at the desk and online.
- Numbers: price, class count and dates are right.
- Names: studio name and booking link right.
- Tone: encouraging, never shaming; easy to ignore.
Privacy rule: Template only; merge names in your booking system. Don't paste waivers or intake forms.

Rules to know before you post or send
The FTC's Health Products Compliance Guidance says health-related claims must be supported by competent and reliable scientific evidence, and that consumer testimonials are never enough on their own to substantiate claims about a health product's effects (FTC guidance). A class description that promises fat loss or injury recovery is that kind of claim, so the class workflow lists any such phrase for you to remove.
For client spotlights, the FTC's Endorsement Guides Q&A says that if you don't have proof an endorser's experience is what people will generally achieve, the ad has to make clear the generally expected results (FTC Endorsement Guides Q&A). If the client got a free session or discount for sharing, say so in the post; the same goes for any brand that pays you or sends you gear (FTC Disclosures 101, FTC endorsements page). The FTC's reviews rule bars fake reviews and incentives tied to a positive review (FTC rule Q&A). Membership and cancellation terms are set by your agreement and your state's health club or gym contract rules; check yours.
What stays out of the chat
Whatever the workflow, don't paste Social Security numbers, ITINs, driver's license or passport numbers, or photos of IDs; bank, card or loan account numbers and routing numbers; health information about a named person: diagnoses, medications, allergies, disability details; passwords and door, lockbox, alarm or gate codes; signed contracts, leases or applications with personal details still on them; anything a client told you in confidence. Use first names or roles, type only the facts a draft needs, and set your AI tool's chat history and training options to the most private choice it offers. The FTC's guide for businesses puts it as take stock, scale down, lock it, pitch it and plan ahead (FTC). If staff use AI tools too, the Small Business AI Use Policy Kit puts these rules in a written policy. The free AI tool risk check shows how much business data is going into AI tools now.

Common questions
Can I say my class burns 600 calories or helps with back pain?
Only with competent and reliable scientific evidence, which is the FTC's standard for health-related claims. Most studios don't have it, so the class workflow describes format, intensity and length instead and flags any health or body promise for you to cut.
Can I post a client's before-and-after or weight loss?
Get written permission first and use their own words. If the post cites a specific result, the FTC's endorsement Q&A says to make clear what people generally achieve if you can't show the result is typical. Many studios skip numbers and celebrate strength or consistency instead.
Do I need to disclose free gear or a supplement deal?
Yes. The FTC's Disclosures 101 says to disclose any financial, employment, personal or family relationship with a brand, including free products, in the post itself with plain words like "ad" or "sponsored". Supplement posts also shouldn't make health claims you can't back up.
What client information stays out of AI tools?
Intake and PAR-Q answers, injuries, medications, pregnancy, weigh-ins, body measurements, progress photos, payment details and signed agreements. Session facts like exercises, sets and loads are fine with a first name or initials.
Can AI write my membership and cancellation terms?
It can rewrite your existing policy in plain English, keeping every price, notice period and fee exactly. It shouldn't invent terms. Your signed agreement controls, and many states have their own health club contract rules, so check yours.
