Every gym has the photo. A member who lost a lot of weight, standing next to a picture of themselves from a year earlier. It's real, it's earned, and the member is proud of it. It's also the single riskiest thing a gym can put in a Google ad.
Two sets of rules meet here. Google's ad policies decide whether the ad runs at all. The Federal Trade Commission's rules decide what a results claim has to say when it does. They don't draw the line in the same place, and the stricter one is the one to follow.
Google's Clickbait Policy Bars Before-and-After Body Photos in Image Ads
Google files the problem under clickbait. Among the ads that policy refuses: "before and after" pictures used to sell a big change to someone's body. Read it next to a gym's Instagram feed and it's hard to miss who it describes. The same policy also rules out clearly altered, zoomed-in body parts.
That reaches every format with images: Performance Max, Demand Gen, Display and YouTube, which are exactly the campaigns from Chapters 10 and 11. A side-by-side transformation photo uploaded as an image asset is an easy way to get that asset disapproved.
Member stories are still usable. A member talking about how the gym changed their routine, their confidence or their strength, filmed in the gym, isn't a before-and-after body comparison. Chapter 10's video shot list works here: coaches, classes and people training, not two photos side by side.
"Eat Whatever You Want and Lose 10 Pounds" Is Google's Own Example of an Unreliable Claim
Google's unreliable claims policy bars claims that lure people with an improbable result as the likely outcome, even if the result is possible. For weight, the trigger is a big number on a short clock, or a result that sounds effortless. Google even writes out the kind of ad it means, one promising a 10-pound drop in a month with no change to what you eat.
Gym ads say versions of this constantly: "Lose 20 Pounds in 30 Days," "Shred 15 Pounds Before Summer," "Beach Body in 8 Weeks." Each one ties a number to a deadline, which is exactly the shape Google flags. Chapter 13 put "Don't promise results or guarantees" into AI Max's messaging restrictions for the same reason. The headlines you write yourself need the same rule.
The FTC's guide for spotting false weight loss claims adds a useful reality check. It says that even for the most effective programs, losing more than a pound a week over a long period is unusual.
"Results Not Typical" Doesn't Fix a Testimonial. The FTC Wants the Typical Result Stated.
Many gyms think a small "results not typical" line makes a testimonial safe. The FTC tested exactly that. In its Endorsement Guides, it reports that neither "Results not typical" nor a stronger version saying most people won't get similar results stopped consumers from reading the testimonial as the normal outcome.
What the FTC wants instead is the generally expected result, stated clearly. Its own example is almost a gym ad: before-and-after pictures of a woman saying "I lost 50 pounds in 6 months." Unless that's what customers generally achieve, the ad should say what they can typically expect to lose in the same circumstances. The FTC's weight loss guide sets a practical trigger: testimonials claiming two pounds or more a week for a month, or more than 15 pounds overall, should come with a disclosure of typical results close to the claim.
Two details catch gyms out. The typical result has to count everyone who started, not just the members who stuck with the program. And if a member received free training, a discount or anything else for their testimonial, that connection has to be disclosed.
Google and the FTC ask for different things here, and you need both. Google requires testimonials that claim specific results to carry a visible note that results aren't guaranteed and can vary. The FTC's research says that note alone doesn't fix a misleading impression. So use Google's note and state the typical result.
In July 2025 the FTC settled with NextMed, a company selling weight loss membership programs, over what it called deceptive cost and weight loss claims, fake reviews and testimonials, and hidden terms. It wasn't a gym, but the pieces are familiar: a membership, a commitment, a weight loss promise and customer stories.
"Stop Hiding Your Belly" Makes a Gym Ad a Sensitive Category and Shuts Off Remarketing
Fitness itself isn't sensitive to Google. Its list of sensitive interest categories doesn't include gyms, fitness or weight loss, so a gym can use remarketing, customer lists and lookalike audiences under the normal rules.
The copy can change that. Google has a sensitive category called imposing negativity, and its examples include body shaming and suggesting negative outcomes for people who don't take a specific action. "Embarrassed at the Beach?", "Stop Hiding Your Belly" and "Summer Is Coming. Is Your Body?" all lean that way. When an ad falls into that category, Google limits it to its own predefined audiences, which means the member list from Chapter 10 and any remarketing quietly stop working for it.
Google also restricts weight loss ads for users under 18 across Search, YouTube and Display. A gym running teen programs should keep weight loss language out of those ads entirely.
A Sports Bra or a Hip-Thrust Shot Can Keep an Image Ad Off YouTube
This one is our reading, not a rule Google has written about gyms. No Google page we found names fitness photos. But Google's sexual content policy limits where ads can run when images show partial nudity or poses that read as sexually suggestive, and gym photography can drift into both: sports bras, shirtless lifters, glute-focused exercises photographed from behind.
On Search, the risk is small. In the image and video formats where Performance Max and Demand Gen spend much of their budget, a limited ad may not serve widely. The fix is cheap: for image assets, choose people fully clothed in ordinary training gear, photographed mid-exercise from angles you'd use in a brochure.
Coaches, Classes and Members Mid-Workout Clear Both Google's Ad Policy and the FTC's
Everything in this chapter points to the same creative. Show the coaches by name. Show a class in the middle of a set. Show members training, laughing, being helped. Use testimonials about the experience, like how the coach explained things and how the member finally felt comfortable coming three times a week, not about pounds lost. Chapter 8 found that members write about the staff, the classes and the coaches more often than the equipment, so that material is already waiting in your reviews.
If you do make a results claim, say what a typical member gets, counted across everyone who started, and put that next to the claim on the page.
A Gym Account Gets Built in Five Stages, and Each One Waits on Conversions
That's the last rule in the guide. Sixteen chapters, one account. This is the build order, stage by stage:
Measure
- Chapter 1: Count new members, not class bookings
- Chapter 2: Start with the searches where people pick a gym
- Chapter 3: Price the click on what a member who stays is worth
Build
- Chapter 4: One ad group, ad and page per program
- Chapter 5: Keep chain names out as negatives
- Chapter 6: Exact match first, then the long tail
- Chapter 7: Bid by program and pick the auctions worth staying in
- Chapter 8: Write headlines from members' own reviews
Launch
Scale
- Chapter 10: Performance Max with the member list and new customers only
- Chapter 11: Demand Gen for people who just moved
- Chapter 12: Local Services Ads as a test, never instead of Search
- Chapter 13: AI Max last, fenced in
Gyms
- Chapter 14: Personal training in its own campaign
- Chapter 15: Offers that state law allows
- Chapter 16: Results claims Google and the FTC allow (this chapter)
Each later stage waits on conversion volume, not the calendar, so a bigger account moves through it faster. The Google Ads for Gyms guide home keeps the rollout table and every chapter in one place.
If you'd rather have it built for you, this is the order we follow for every gym on our Google Ads management plans.
