The fitness industry is quietly turning into a measurement industry

The fitness industry spent 30 years selling effort. The next 30 will be spent selling evidence.

That is not a slogan. It is what the spending data shows, and what the biggest names in the business have already repriced around. The sector that used to be gyms and classes is being absorbed into something much larger and much closer to medicine, and the numbers behind that shift change what you should expect from anyone you pay to look after your health.

What the numbers actually say

The global wellness economy reached 6.8 trillion US dollars in 2024 and is forecast to reach 9.8 trillion by 2029, according to the Global Wellness Institute. It grew 7.9 percent between 2023 and 2024 and is projected to grow 7.6 percent a year through 2029.

For scale, it is now close to 4 times the size of the pharmaceutical industry at 1.8 trillion, and about 60 percent as large as all global health expenditure combined. Asia Pacific alone accounted for 2.03 trillion dollars in 2024, growing 9.3 percent year on year, faster than the global average.

The money is moving from exercise to measurement

Inside that total the sectors are not growing evenly, and the pattern tells you where the industry is heading.

Physical activity, which is gyms, studios, equipment and coaching, is the second largest sector at 1.14 trillion dollars, but it grew at 4.6 percent a year between 2019 and 2024. That is below the overall market.

Public health, prevention and personalised medicine sits at 675.9 billion and grew at 8.6 percent a year over the same period, nearly double the rate of physical activity. Mental wellness, at 268.3 billion, grew fastest of the large sectors at 12.4 percent a year.

So the category growing slowest is the one selling the workout. The categories growing fastest are the ones selling the diagnosis, the measurement and the management.

Equinox did the maths before anyone else

The clearest signal did not come from a hospital. It came from a gym chain.

At the end of May 2024, Equinox launched Optimize by Equinox. It costs 36,000 US dollars a year on top of a required 6,000 dollar membership, so 42,000 dollars all in. The programme includes around 16 hours of practitioner time a month across personal training, nutrition counselling, sleep coaching and massage therapy, and it is built on a blood panel of more than 100 biomarkers run with Function Health. It launched in New York only, to a waitlist.

Note what Equinox did not do. It did not add a longevity class or a recovery lounge. It partnered with a diagnostics company, put blood work at the front of the programme, and priced the whole thing at roughly 30 times a normal premium membership. Julia Klim, Equinox’s VP of strategic partnerships, framed it as a health and quality of life plan rather than a shortcut, and said plainly that you cannot hack your way out of bad habits.

That is a fitness company saying the quiet part out loud. The training is not the product. The reading of the numbers, and the hand on the plan when a number does not move, is the product.

The measuring companies are growing faster than the gyms

Function Health, the partner behind that panel, is the second signal.

In November 2025 it raised 298 million US dollars at a 2.5 billion dollar valuation, taking total capital raised to 350 million. By that point it had run more than 50 million lab tests since 2023, offered testing through 2,000 Quest locations and was expanding whole body MRI to 200 sites.

Hold those two numbers next to each other. Physical activity, a 1.14 trillion dollar sector with a century of history, is compounding at 4.6 percent a year. A blood testing company that did not exist in 2022 is worth 2.5 billion dollars. The capital is not confused about where this is going.

Why the loudest voices in health are no longer trainers

Ten years ago the most influential people in fitness were trainers and athletes. Today they are doctors and quantifiers, and the audience numbers are not close.

Andrew Huberman, a Stanford neuroscientist, runs a podcast with 7.5 million YouTube subscribers. The content is mechanism and protocol, not motivation.

Peter Attia, a physician, published Outlive in March 2023 and it became a New York Times bestseller. The book’s central argument is that you should measure and act decades before anything is wrong, which is a clinical argument sold to a general audience at scale.

Bryan Johnson is the extreme end and the most useful data point. Bloomberg reported in January 2023 that he was spending roughly 2 million dollars a year on his protocol. He then packaged it. Blueprint raised 60 million dollars in October 2024 and now sells a consumer subscription at 333 dollars a month. Whatever you make of the man, 60 million dollars of institutional money went into the idea that ordinary people will pay monthly to have their own numbers managed.

None of these three sells a gym. All three sell measurement. And all three built their audiences in under 5 years.

Why measurement is not a marketing angle

Two large studies explain why this shift is rational rather than fashionable.

A Cleveland Clinic analysis of 122,007 patients who underwent treadmill testing, published in JAMA Network Open, followed them for a median of 8.4 years. After adjustment, the people in the lowest fitness group had more than 5 times the all cause mortality of those in the highest, a hazard ratio of 5.04. In the same study coronary artery disease carried a hazard ratio of 1.29, smoking 1.41 and diabetes 1.40. Low cardiorespiratory fitness was associated with a larger increase in risk than any of them, and the authors found no upper limit to the benefit of being fitter.

The PURE study, published in The Lancet, followed 139,691 people across 17 countries for a median of 4.0 years. Every 5 kilogram reduction in grip strength was associated with a 16 percent higher risk of death from any cause. Grip strength predicted all cause and cardiovascular death more strongly than systolic blood pressure did.

Both of those are measurements. Neither is a workout. You cannot tell where someone sits on either scale by looking at them, by asking how their training feels, or by counting sessions attended. That is the whole reason the industry is repricing around testing, and it is why a programme that never measures you is selling you a feeling.

Thailand’s version came out of the hospitals

Thailand is not behind on any of this. It is ahead of most of the region, and it got there from the opposite direction.

Bangkok has had integrated medical prevention for years. BDMS Wellness Clinic, part of Bangkok Dusit Medical Services, runs blood analysis, genetic and epigenetic testing and hormone profiling, alongside musculoskeletal assessment and rehabilitation. VitalLife at Bumrungrad, RAKxa and Chiva Som all sit in the same space. They are serious operations and they are good at what they do.

But look at the shape of them. Every one is a medical business that added exercise. The doctor is the centre of the model and the training is a service around it, often delivered in a week long stay or a quarterly review.

Equinox went the other way, and that difference is the whole argument. A coaching business that adds measurement ends up with something a clinic structurally cannot produce, which is somebody in the room with you 3 times a week who has read your numbers and can change the plan on Tuesday. A panel of 100 biomarkers is a photograph. Coaching is the film. The reason Equinox could charge 42,000 dollars a year is that it sold both, and the reason most testing gets wasted is that almost nobody sells both.

Aspire has been built from the gym floor up, in Asok, since 2002. The coaches and the physiotherapists work in the same building on the same client file. The Healthspan programme adds blood work, VO2 testing and DNA testing read with our medical partner, so the training, the rehabilitation and the food are written off one set of numbers rather than three people guessing separately.

That is the same direction of travel Equinox took in New York in 2024. The difference is that in Bangkok it is 24 years of coaching with medical measurement added, rather than a hospital adding a gym.

What this means if you are buying coaching

The practical consequence is that the questions worth asking a coach, a gym or a clinic have changed.

The old questions were about the programme. How many sessions, what equipment, which method. Those no longer separate anyone, because the answers are broadly the same everywhere.

The questions that separate providers now are these. What do you measure at the start. How often do you measure it again. Who reads the result. And what happens to the plan when a number does not move.

At Aspire that is the structure rather than an add on. A client starts with a full baseline, which is body composition on InBody, a movement screen, grip strength, a one leg stand, a sit to stand and strength testing. Body composition is read again every 2 weeks. Strength, capacity and cardio threshold are retested across a full cycle each quarter.

That is also why the physiotherapy team sits on the same floor as the coaching. The merge the industry data describes at a market level has to happen at the level of one person’s file, or it is just 2 invoices.

How to start

You do not need a longevity clinic to act on any of this. You need a baseline you can repeat.

Get your cardiorespiratory fitness measured rather than estimated. Get your body composition measured rather than weighed. Get your grip strength recorded, which takes under a minute. Write the numbers down with the date. Repeat them on a fixed schedule, not when you feel like it.
