Your gym, your trainer, your physio and your dietitian don’t talk to each other.
Here they do.
Everything you do with your body in one place, and everyone who helps you inside it. From the first squat to coming back from an injury, without changing application.
The problem is not that you lack an app. It is that you have four.
Your trainer sends a PDF
Written once, never updated by what you actually lifted.
Your physio hands you a sheet of paper
Which nobody at the gym will ever see, least of all the plan that loads your shoulder.
Your gym has an app that opens the door
And knows nothing about the training that happens on the other side of it.
We checked, product by product, against 41 competitors. Gym apps carry nothing on rehabilitation, posture, water or adapted work. Clinical platforms never leave the clinic. Older-adult apps do no strength. Nobody occupies the middle — and the middle is where a real person lives.
Pick the one that is you
You will be able to come here to use the service and to offer it. Both sides will start free.
You say whether you managed it. It decides the rest.
Weight and reps come from your own history, not a template. It works with no signal, because a gym is usually a basement. And what you write about your body, your pain and why you missed a week cannot be read by anyone — not your gym, not us.
Coming with the first release. What lands first
Six people, six private accounts. Not one shared login.
Each person keeps their own history and their own privacy. A minor is under guardianship, and on reaching the age of consent their key rotates and the guardian’s access closes by itself — nobody has to remember to revoke it.
Specified. Not built yet.
The first centres on the list are the ones that will form the map.
The gym account will be free, and will consist of your gyms and your machines — nothing else. It will train nobody, hold no members and never be told who chose it. A member who says “I train here” will get that gym’s exact equipment. Paying will be a separate decision that gives you your own instance for your own members.
Specified in full. Building. What a gym gets
Your clients grant you access. You never request it from the system.
You see and adjust exactly what they have handed you, and they can withdraw it in one move. A public listing if you want one, behind two switches — yours and ours — both off by default, and never turned on by an upgrade or a migration.
Specified in full. Building.
Verified against your registration, with a record of who checked it.
Verification is the mechanism, not a badge: it is what decides whether a plan reaches a person whose own health questionnaire has already flagged something. Spain first, because a register has to be read for real before a country can be added.
Specified. Not built yet.
Enrol your patients and build the actual table: days, exercises, intensities.
A verified registration is the only thing that reaches the prescription-only part of the catalogue — the material nobody can prescribe to themselves. What the patient writes stays the patient’s; what you write is on the record.
Specified. Not built yet.
The same as a physiotherapist, at the scale of a centre.
The clinic is the place of work; your named, verified professionals do the prescribing. A clinic prescribes nothing on its own, and that boundary is written into the account rather than into a policy page.
Early access, by request.
Programme your residents without paper.
And a resident who can lift weight goes on lifting weight. The category filters what is offered; it never cuts down what a person is allowed to do. That rule is the whole reason the capacity ladder exists as a ladder.
Early access, by request.
GymAI opens with 10,244 exercises. Eight worlds. One catalogue.
The largest gym app that publishes a figure claims 1,600 — and contradicts itself on its own site.
Strength & conditioning
Barbell, dumbbell, cable and machine work, calisthenics by progression rung rather than by kilos, and cardiovascular work with its protocols.
Mind-body
Yoga style by style, tai chi form by form, qigong, pilates, breathing and meditation. So that when you arrive wrecked by stress, what follows the strength work is calm.
Sport & movement
Agility, speed, sport-specific work, combat, dance, joint mobility, and the traditions no catalogue bothers to list.
Rehabilitation & clinical
160 named conditions: Parkinson’s, stroke, multiple sclerosis, cardiac, respiratory, oncology, hand, TMJ, vestibular, lymphoedema, amputation.
Postural correction
Ordered by the fault you actually notice — forward neck, rounded shoulders, one shoulder higher — not by the name of a muscle.
Pregnancy, postpartum & pelvic floor
By trimester and by stage, hypopressives included. A whole stage of life that fitness software simply skips.
Older adults & capacity
A four-rung ladder with its own field tests, for people starting from nothing. And it goes upward: it ends in loaded work.
Water
Swimming by distance, stroke and pool length, plus aquatic work for people who cannot yet load a joint on land.
A person is not eight markets. The same body squats, swims, gets injured, gets pregnant, gets older — and the plan should follow them across all of it without a second subscription.
rows are seated, supported or adapted
Spread across all eight worlds, not gathered into a section. Adapted is not a separate app and not a separate market — it is the same catalogue, and that is exactly the difference.
carry a Spanish name of their own
Not an automatic translation of the interface: each exercise carries the name it is actually called by, written for the place it is used.
We went through 41 competing products, one by one. Not one covers more than two of these eight.
Things the other forty-one do not do
Equipment types, and the makers of them
Say you have the Technogym Selection line and your machines are ticked for you. Zero of the 41 competitors let you filter by brand at all.
The session runs in a basement
Logging, rest timing and the plan all work offline and reconcile later. Where gyms actually are, connectivity is not a given.
Posture is a first-class reason to train
Not a stretching add-on. You pick the fault you see in the mirror and the work is built from there.
Pregnancy, postpartum and hypopressives
By trimester and by stage, in the same catalogue as the barbell work — a stage of life the industry leaves to a separate app, if it covers it at all.
Clinics and care homes are not an afterthought
They are account types with their own boundaries, written before a line of their code — not an enterprise page bolted onto a consumer app.
Every change says why it happened
A weight moves because of a set you logged, and the sentence naming that set travels with the change into your history.
The loop, at the size you will hold it
Interfaces as specified, down to the plate maths and the wording of the reasons. The engine that drives them is built and tested; the exercise imagery is not in yet.
One picture per movement, shot the same way, whatever the discipline
Same angle, same neutral ground, whole body in frame. A warrior pose and a barbell press are treated as the same kind of thing, because in this catalogue they are.
What you write about your pain, your measurements and why you missed a week never leaves your key.
No recovery copy. No operator key. Nobody at GymAI can read it, and neither can your gym, because there is no mechanism by which they could — not a policy saying they will not. Of the 41 competitors we examined, not one declares end-to-end encryption. The sector leader’s policy does not contain the word.
No advertising
There is no ad product, so there is nothing to profile you for.
No telemetry
The product does not report your behaviour back to us.
No third-party calls
No outside scripts, no pixels, no cookies that are not ours — on this page either.
Access you grant, and withdraw
A trainer or physio sees what you handed them, for as long as you leave it handed over.
Put your gym on the map before we open.
The map of where people train, and of what is actually on each floor, will be built out of the centres that are on the list when it opens. The first centres in are the ones that form it. A chain describes each gym separately, because the equipment differs between them and an inventory averaged across sites is wrong everywhere.
- The account will be free, and will hold your gyms and your machines. One gym or twenty: there is no fourth thing in it.
- It will train nobody, hold no members and never be told who chose it. A member who says “I train here” will get that gym’s exact equipment, and their plan will stop offering machines you do not own.
- Paying will be a separate decision, not an expiring trial: it provisions your own instance so you can serve your own members.
Joining the list creates no account, publishes nothing and claims nothing. We write to you when we open, and your gym is already described. We never ask how many members you have.
You can come here to offer the service, not only to use it
Where a profession is regulated, the account will be verified against a real register, and the check recorded with who made it. Joining the list asks for none of that: we will never take a registration number we cannot yet check.
Personal trainer
Client-granted access and an optional public listing behind two switches.
Dietitian
Verified registration, Spain first. Nutrition plans delivered through the same permissions.
Physiotherapist
The only account that reaches prescription-only material, because the register says so.
Clinic, care home, day centre
The centre is the place of work; the verified people inside it do the prescribing.
Join as a professional
Pick the one that describes your work and we will write to you when your account type opens — not before, and not about anything else.
The leading trainer platform exists in English only, and says so in its own help centre. Draw your own conclusion about who it was built for.
What is ready, what lands first, what we are still building
No launch date, no prices and no promises we cannot keep. This section is updated as the build moves, and it is the honest version of every claim above it.

Working today
The engine, the screens and this list
The progression engine is built and tested, thirty-five screens are drawn and specified, and the waiting list works from today. The waiting list is the only thing on this page you can use right now.
-
Finished, waiting to land
The full catalogue and the equipment map
10,244 exercises across the eight worlds, 794 equipment types and 139 manufacturers — researched, verified and ready to import. This is the next thing you will see.
-
Building
Accounts, the map, languages and the plan generator
Personal and family instances, Spanish and Catalan, the trainer and dietitian accounts, the gym account and the map it draws, and the routine generator that turns your history into next week. All specified in full; none of them shipped.
-
Specified, decisions open
Physiotherapists, clinics and care centres
Written in full before any code, and deliberately held until one question about patient keys is answered properly. We would rather be late than answer it by accident.
There will also be a simpler build you can download and run yourself.
The six things people ask before they join
What is GymAI?
One place for the whole chain around one person: the gym, the personal trainer, the physiotherapist and the dietitian. It reads what you did, decides the next weight and the next reps, and asks you only whether you managed it.
Can I use it today?
No. The waiting list is open and the product is not. There is no date, and this page will not invent one — joining the list is how you hear first.
Is it open source?
No. The licence is our own, and GymAI should never be described as open source. Being able to run it yourself and being open source are different things.
Who can read my training data?
It is encrypted on your device before anything is sent, and the server never holds a key. There are no analytics, no telemetry and no third-party calls — including on this page.
Do I need a gym or a professional?
No. It works for somebody training alone. Where other people are involved, each of the six has a private account of their own, and access is something you grant rather than something they request.
What happens when I join the list?
You give an address and say which of you it is. We send one email; you are on the list only once you follow the link in it. One list, never a list per role, and you can leave from any message we send.
