Today’s episode is a deconstruction of a brand that has done something extremely rare: It has scaled to $35 million in revenue by building creative systems for a specific audience that most brands ignore. This is JustFit, a fitness app focused on at-home workouts for plus-size women. That’s incredibly specific, as you can see.

In this episode, I break down 381 of their ad scripts, analyze their creative loops, unpack their hooks, and lay out the system behind their success. We also talk about what they could do better and how you can build on their learnings, even if you’re in a completely different genre altogether.

JustFit’s Differentiating Positioning

What makes JustFit different? In a word, it’s positioning. It’s not just about home workouts or fitness made easy. It’s built for women who feel left out of traditional fitness culture. The scripts repeatedly call out women over 160 lbs, women over 200 lbs, and women over 300 lbs. You can see some examples here, like “plus-size girls” and “chubby girls.” There’s also a focus on laziness and ease of use.

These aren’t one-off mentions. These are distinct personas with their own emotional arcs, body pain points, and motivational loops. You can see other examples of personas like women who focus on scripts based on challenge, love handles, age-specific concerns, or “revenge body.” There are a lot of very different angles here. Interestingly, they also do a great job of selling the emotional context for someone who hates gyms, feels overlooked, and needs something that can be done in their PJs. You can see that when you look at some of their script examples.

That’s the big emotional unlock. As we like to say on our team, you have to build ads not just for algorithms, but for humans. Algorithms can perhaps get you the first couple of views, but speaking to real human emotions is what drives long-term engagement and success.

Their Deeper Messaging System

Let’s look at their deeper messaging system. You can see phrases like “see the difference in one month,” “see the difference in two weeks,” or “see the difference in three weeks.” This chronology makes a huge difference; it gives people the hope of progress and success. You can see some of these here as well: “Day one, day two, day three, day four, morning, afternoon, evening.” Really having that progression makes a huge difference.

There’s also messaging like, “My roommate is lazy,” “Caught my wife doing this,” or “My sister has lost a lot of weight.” You can see some of this, and that builds social validation without necessarily sounding like an ad. It builds proof; it’s implied testimonial.

If you look at their top hooks based on the number of days these ads have been running, you’ll find phrases like “Lost 10 pounds by being lazy” or “Wanted to lose 10 pounds, didn’t know where to start.” Again, these are speaking to objections. “Mommy pooch is real” calls out a real audience segment. And again, this objection handling, like “I know this looks weird” or “I know that this looks crazy.” There’s also third-party storytelling: “My little sister does XYZ,” or “My little sister is so weird,” which is kind of self-deprecating.

A lot of this is disarming, informal, and fun, and it’s clearly inspired by user-generated content. Interestingly, these aren’t real testimonials, but they’re scripted to feel real, which again underscores the fact that what’s important is manufacturing the feeling of authenticity through your ads.

What you can also learn from this is how a lot of this can be modular. For instance, let’s use personas and combine this with angles and outcomes:

• Women over 200 pounds, angle: Lazy butt workout, outcome: Friends will ask your secret.
• Women over 30, angle: Confidence, outcome: Start seeing change in two weeks.
• Postpartum moms, angle: Belly fat, outcome: Feel different in a week.

This grid, this mix of permutations and combinations, can be mixed and matched to give a ton of possibilities to test and try, which you can basically do with AI very, very quickly if they wanted to really scale this.

Opportunities for Improvement and Expansion

Now, what are some things they could do better and differently? Right now, a lot of the focus is on “lazy” and “ease of use.” I see that makes sense because you want to call out ease of use, and “lazy” is a bit of a power word – it’s a charged word that can elicit a click. But I wonder what if we shifted that to power?

What if we shifted that messaging to talk about how people could be empowered? Phrases like, “I stopped hiding and started owning my body, now I feel unstoppable,” or “They said I couldn’t do X, I proved them wrong.” Similarly, more aspirational language around lifestyle and how fitness bleeds into lifestyle. For instance, “My ex hit me up, I just said no.” What are their broader emotional lifestyle goals, not just fitness goals? I think those could be great ways to expand for them.

There is quite a lot of UGC here, but I think it would be interesting for them to do more infographics, split-screen “noob versus pro” visuals, and skit-style ads. I think those would be interesting for them to try and test. Given that they have a huge collection of modular scripts, this is a great place for them to lean into AIGC to amplify their testing as well.

Key Takeaways for Your Marketing Strategy

In summary, here are a couple of things you can apply right now from this playbook:

• Lean on progression: Day one, week one, week three.
• Talk about how the user’s state changes.
• Use third-party storytelling for implied social proof: “My roommate thought I was nuts.”
• Target specific identities: Women over 170 pounds, new moms.
• Create story frameworks that you can AI-generate.
• Test disarming hooks that feel informal.

Closing Thoughts

JustFit is a great study in niche identity-based marketing. They’ve built a great modular creative system that runs on specific personas, repeatable story arcs, and social proof as narrative. They have a ton of opportunities with aspirational identity building, generative AI workflows, and more variety in visual storytelling.

If you’re building your own creative systems, I hope you can take inspiration from what JustFit has done, add your voice, add your audience, and your AI muscle.
