Fitness this week: August 10

This is the first edition of a brief we'll publish every week: what happened in the fitness industry, written for coaches, no filler. The idea is simple. If you read this, you already know what the week was about and what it means for your business.

Three headlines defined the days. Smart Fit, Latin America's largest chain, posted its best quarter ever on August 6 and now runs 1,759 gyms across 15 countries. That same day Planet Fitness reported $365 million in revenue in the United States and a number that works as your own thermometer: 3.5% monthly attrition. And venture money came roaring back to fitness, $3.6 billion in the first half of the year, almost all of it betting on artificial intelligence and data, not machines.

As The Rio Times reported on August 6, Smart Fit closed the second quarter of 2026 with a record EBITDA of 712 million reais and a net profit of about $40 million. The chain added 290 gyms in a year to reach 1,759 locations across 15 countries, with 5.3 million members and especially fast growth in Mexico and the rest of Spanish-speaking Latin America. Its TotalPass aggregator, the corporate pass that unlocks multiple gyms, already has 2.2 million users. The stock still fell 8% on margin pressure.

Why it matters: the mass, low-cost gym model is expanding across your markets, and you won't beat it on price or on machine count. There Smart Fit is unbeatable. Your ground is what a budget club can't give: personalized programming, follow-up, and a person who remembers the client. Watch the aggregators like TotalPass or Gympass too: they change where the client feels they "belong," and if you're not in that conversation, the generic membership walks off with that relationship.

Planet Fitness reported on August 6, per StockTitan: $365.2 million in revenue, up 7.1% year over year, with 2,930 clubs after opening 23 new ones in the quarter. Two figures matter more than the top line: penetration of its premium Black Card membership hit 68%, and average monthly attrition held at 3.5%.

Why it matters: that 3.5% monthly is the thermometer of a high-volume gym with almost no coaching, and it works out to losing roughly 40% of the book in a year. That's your baseline. If your retention as a coach looks like a chain that talks to no one, the relationship isn't doing its job, because that closeness is your one edge over them. On the bright side: 23 new clubs are thousands of people starting to train who, in a few months, will want someone to tell them what to do.

Athletech News picked up this week's report from Mark Gurman (Bloomberg) that Apple has spent about a year evaluating a redesign of its wearable line, including the option of a device with no screen at all, in the vein of Whoop and Oura. Gurman notes it's unlikely to arrive in 2026 and is one of several ideas on the table, but the signal is clear: the category is moving toward discreet bands that measure recovery and use AI as an always-on health companion. Google and Garmin already launched their own screenless bands this year.

Why it matters: more and more clients will show up with a recovery, sleep, or strain score on their wrist. The coach who can read that data and adjust the load, pull back after a bad night, push when the body is ready, looks modern and useful. The one who ignores it looks dated. The opposite trap is just as real: a recovery score is not a program, and your judgment still beats a ring. Use the data, don't let the data use you.

Athletech News reported on August 14, citing Crunchbase, that fitness and wellness startups raised $3.6 billion in the first half of 2026, about a third more than all of 2025, which had been the sector's worst funding year in at least six. The key detail isn't the amount but where it goes: investors are fleeing pure hardware and betting on AI wearables and platforms that collect data continuously. The year's biggest round was Whoop's, at $575 million.

Why it matters: the "AI coaching" products competing for your client's attention will be better funded, cheaper, and more polished every quarter. Don't fight that on its own field. Your moat is what no funding round buys: judgment about what to do with a real person, and the accountability to make them do it. AI replaces the spreadsheet, not the coach.

ScienceDaily covered on August 8 a study built on three US cohorts that followed nearly 150,000 health professionals for up to 30 years, with about 36,000 deaths recorded. People who did between 90 and 120 minutes of strength training per week had roughly 13% lower risk of dying from any cause, 19% lower from cardiovascular disease, and 27% lower from neurological disease, mainly dementia.

Why it matters: this is a sales and retention argument backed by hard evidence, not an aesthetic promise. For the 40- or 50-something client who trains not to look better but to live better, you have a concrete figure and a programmable dose: 90 to 120 minutes of strength a week, which fits in two or three sessions. Keep the number and the source; it persuades better than any motivational line.

Second-quarter earnings season continues: more platforms and chains report in the coming days, and that's where you'll see whether the sector's growth is broad or only the low-cost giants. It's also worth watching whether Apple's screenless-wearable rumor hardens, because it would set the pace for the whole category.

And keep an eye on funding rounds: with $3.6 billion already moved, the next big AI-coaching app round is only a matter of time. We're back next Monday with whatever happened.
