Picture a gym that sells two plans: a month-to-month membership you can cancel whenever you like, and a cheaper 12-month agreement with an early-cancellation fee. Both are on the pricing page. Both are honest.
Now picture an ad for the 12-month plan with the headline "Cancel Anytime." Nobody at the gym wrote it. Google did, by lifting two words from the month-to-month block on the same page. That's the risk this chapter is about. The culprit is AI Max. It composes headlines out of your own site's copy, and gym sites are crowded with sentences that hold for one plan and not the next.
AI Max Is the Last Switch in a Gym Account, and It Stays Out of the Exact-Match Campaign
AI Max does two jobs. It widens the searches your ads can show on, much as broad match does, and it writes extra headlines and descriptions from your landing pages. Chapter 9 had you switch it off when you built the first campaign, because Isolation exists to spend only on exact searches you chose, bid by hand. AI Max doesn't belong there at any point.
It comes last. By the time it's worth turning on, the account has already done the work in this guide's order: Isolation proved which searches bring in members, Exploration took the best of them to broad match once there were about 30 quality conversions a month, then Performance Max, then Demand Gen, and the conversion tracking from Chapter 1 has months of clean joins behind it. Then AI Max can be tried in the broad-match side of the account, where widening reach is already the point.
Like every later step, the gate is conversion volume, not a date. A gym with a bigger budget gets there sooner. The fence in the rest of this chapter goes up before the switch is flipped, not after the first bad ad.
Four of Twelve Gym Sites Sell "No Commitment" and a 12-Month Contract Side by Side
We looked closely at 12 gym and studio websites in our example market, Austin. Seven used contract language somewhere: "no long-term contract," "no commitment" or month to month. Four sold a 12-month commitment alongside a plan with no commitment at all.
The clearest example is a national chain's club page. It lists a plan headed "No Commitment! ... Cancel Online, Anytime!" directly beside two plans that each say "12 Month Commitment." A boutique studio chain's page lists 12-month and 6-month plans next to a feature list that says "Month-to-Month Contract," and advertises a "30-Day Risk-Free Guarantee" whose fine print requires 12 sessions in the first month. A Pilates studio sells 12-month commitment tiers above a month-to-month block that says "Cancel anytime with notice." An independent gym offers month-to-month memberships beside commitment memberships with early-cancellation fees of $150 or $300.
None of these pages is wrong. Each promise is attached to the right plan. The problem is that an ad isn't attached to anything. A headline that says "Cancel Online, Anytime" shown next to a description about the 12-month price is a promise the gym didn't make, and Chapter 15 covers why several states take contract and cancellation claims in gym ads seriously.
AI Max Writes From Whatever Is on the Page, Including the Holiday Banner From Months Ago
Google is candid about where the words come from. Its help page on text customization, the AI Max setting that writes ad text, says it takes snippets from your landing page titles, descriptions and meta tags, and rewrites from there. Edit the page and the ads follow within two days; Google rechecks the generated text on that cycle. And it puts the burden on you: make sure your website content is accurate and not misleading.
That's a real ask for gym websites. Across our 12 example sites, seven stated some fact two different ways: the founding year, the number of locations, the open-gym hours, the joining fee's "regular" price, or a six-month minimum on one page and a seven-day cancellation notice on another. Three had stale copy still live, including a holiday closure banner for a date months past and an about page saying a location "should open in 2022."
A person reading those pages makes sense of them. AI Max doesn't guarantee it will. So before the switch goes on, fix the pages the ads point to: one price per plan, one set of terms per plan, nothing out of date. It's the cheapest protection in this chapter, and Google's own help page asks for it.
Google Lets You Ban 25 Terms From AI Max. "Cancel Anytime" and "No Contract" Belong at the Top.
Google's fence is called text guidelines, and it has two parts. It's still labeled a beta, so treat it as a help, not a guarantee.
The first part is term exclusions: up to 25 exact words or phrases per campaign that the generated text must never contain. Capital letters don't matter. Language does, so a gym that also advertises in Spanish needs "cancela cuando quieras" on the list as well. For a gym, the list starts with the contract words, then the words that promise results:
- cancel anytime
- no contract
- no commitment
- month to month
- risk-free
- guaranteed
- free trial
- no enrollment fee
If your gym really is month to month with no fees, you can still say so. Put it in a headline you wrote yourself, in the ads from Chapter 8. The exclusion only stops Google from saying it on your behalf, next to a plan where it may not be true.
Part two holds sentences rather than single words. Google calls them messaging restrictions, caps them at 40 a campaign, and advises tucking a sample phrase into each one. Google also notes that term exclusions can't stop generated text that includes prices, and that a messaging restriction is the way to handle those. For a gym, three restrictions cover most of the risk:
- "Don't mention contract length, commitment or cancellation terms, e.g. cancel anytime, no contract, 12-month agreement."
- "Don't mention prices, fees or discounts, e.g. $0 enrollment, $1 down, $24.99 a month."
- "Don't promise results or guarantees, e.g. lose 20 pounds, see results in 30 days, risk-free."
The results rule matters for Chapter 16, where Google's and the FTC's limits on transformation claims come in.
Google's 10 Sample Headlines Show Whether AI Max Will Write "Cancel Anytime" Before It Spends a Dollar
You don't have to switch AI Max on blind. When you enter a landing page, Google generates a sample of up to 10 example headlines and descriptions, and the preview filters them through the text guidelines you've set. Read every one against the page it came from. If a sample attaches a promise to the wrong plan, or repeats something stale, fix the page or add a guideline before launch.
Then keep reading after launch. Because the text is refreshed at least every 48 hours, what AI Max wrote last week isn't necessarily what it's writing today. Check the generated assets on a schedule, the same way Chapter 6 had you read the search terms report. When one says something you wouldn't have written, remove it where Google allows, and add a guideline so it doesn't come back.
If the checks keep turning up problems, turn it off. AI Max is the last expansion in this rollout because it's the one that gives Google the most freedom. A gym account that's already profitable across its other campaigns loses nothing by waiting until the fence holds.
Next: Personal Training Gets Its Own Campaign
Chapter 14 takes personal training out of the membership account entirely. Training clients are worth more, cost more to reach and search differently, so they get a campaign built just for them. If you're weighing pay-per-lead listings for that program, Chapter 12's four conditions come first. The Google Ads for Gyms guide home shows the three chapters left.
For gyms on our Google Ads management plans, AI Max stays off until the rest of the account is profitable, and the text guidelines are written before it's ever switched on.
