We read every creative that twelve AI workout planner apps ran on Meta from 1 September to 4 October 2026, more than 2,200 of them, and sorted them by message, hook and idea.

What this means if you advertise in this category

  • What everyone says: the app tells you what to lift. 32% of the creatives make their case by showing the app at work, and 51% are creator content.

  • What almost nobody says: why to believe it. Only 3% argue with user reviews, and 2% compare the app with an alternative.

  • A test worth running: compare the app with the alternatives. Only 2% of creatives do; Gravl is the outlier at 21% of its own.

Twelve apps chase one buyer: someone who trains in a gym

28 distinct markets

The promise is the right sets, reps and weight, often in the same words

Most open on a pain point (28%) or an open question (26%), then show the app.

  • Fitbod and Planfit share one line in their ad text, word for word: "will guide you through the right sets, reps, and weight to reach your fitness goals."

Fitbod, Planfit and FitnessAI creatives side by side

The feeling splits them: the body you want, or calm at the gym

Aspiration is the main feeling in 62% of creatives; four smaller apps lead with relief.

  • Muscle Monster plays on aspiration in 88% of its creatives, Gravl in 68% and Fitbod in 66%.

  • Aitofit, Gymverse, FitnessAI and Planfit play on relief in 36% to 52% of theirs, against 13% overall, more than on aspiration. Planfit: "Random workouts. Gym anxiety. The same routine every week."

Two break the pattern: Freeletics opens on a price, Muscle Monster on a chart

Where most open on a problem or a question, these two lead with something else.

Freeletics and Muscle Monster creatives side by side
  • Freeletics hooks with an offer in 59% of its creatives (7% overall) and shows a discount in 93% (11% overall).

  • Muscle Monster runs infographics in 65% (18% overall) and opens on a big promise in 36% (15% overall), as in "28-day chair tai chi weight loss program".

Nine apps put most of their creatives into one idea

Creatives that share one concept count as one idea, even when each is shot differently. The biggest, Muscle Monster's exercise charts, holds 21% of all creatives.

  • The most shared: a creator opens on a question, then shows a result. Six apps run it, Fitbod in 37% of its creatives.

  • The relief side has its own: the newcomer lost at the gym (Aitofit 94%, Planfit 57%). Tsemppi: "Let Tsemppi help you stop guessing at the gym."

All of this is what Meta shows publicly, with no spend or results

It shows what these apps run, not what works.

  • Every creative running from 1 September to 4 October 2026 in 28 markets worldwide.

  • A market counts when a creative reached it, which is not the same as being targeted at it.
