Interactive Anatomy Platform
Understand your body.Train smarter.Recover better.
Explore the human body in 3D. Understand where your pain comes from, and what actually helps.
Free for everyone. No account required.
Exercise Library
Every movement, explained.
22 exercises so far, each written with coaching cues and linked back to the anatomy it works on: the muscles it targets and the problems it's used for. Free to read, no account.
Who it's for
Built for the people who explain the body for a living.
Momentum is made for professionals who need anatomy to be both accurate enough to trust and clear enough to show someone else, and for anyone curious about how their own body works.
Physical therapists
Outpatient, ortho and sports PTs explaining an injury a dozen times a day.
Turn the body to the structure you're treating and show it. Then read the same record's attachments, innervation, movement tests and exercises, each carrying its source and its review status.
Chiropractors
Practitioners whose whole model is showing patients how the spine, joints and nerves work.
Isolate a region and drop into the skeletal or nervous layer live in front of a patient, with the written anatomy behind it rather than a poster on the wall.
Athletic trainers
ATs handling evaluation, rehab and return-to-play conversations on the spot.
Pull up the muscle, joint or nerve involved in a strain or sprain and explain it to an athlete in seconds, with the condition and rehab detail on the same page.
Strength coaches & personal trainers
S&C coaches and trainers who have to answer "what does this actually work?"
Show a client the muscles a lift loads and what the joint is doing, and check your own understanding against a cited record instead of a forum thread.
Massage therapists
Clinical, sports and treatment-focused therapists working by feel and by map.
Origins, insertions, fascial relationships and trigger points (the details this work runs on), as a reference you can hold open between clients.
And anyone with a body.
Students, patients, athletes and the plainly curious. The interactive 3D atlas is free for everyone: no account, no trial. A membership starts at $9.99/month and unlocks the written library behind every structure.

Questions
What to know
Straight answers about the atlas, membership, and how Momentum handles what it does and doesn't have yet.
What is Momentum?
Momentum is an interactive anatomy education platform. At its heart is a 3D human body you can rotate, zoom, search and explore (free for everyone). A membership unlocks the full educational library behind each structure.
Can I explore the body without paying?
Yes. Rotating and zooming the body, panning, searching anatomy, switching between muscular, skeletal and nervous systems, and highlighting any structure are all free, always. When you select a structure you'll see its name and a short description at no cost. The in-depth educational content is what a membership unlocks.
Why is Premium required for the detailed content?
Building and maintaining an evidence-based anatomy library (writing it, reviewing it, and keeping it accurate) is ongoing work. Memberships fund that work and let us keep the interactive atlas free for everyone.
What does Premium unlock?
The full article for every structure: origin and insertion, function, innervation, blood supply, clinical significance, pain patterns, exercises, related anatomy and associated conditions. Educational videos and AI-guided answers are planned and will be included as they're released.
How much does membership cost?
Two plans. Personal is $9.99/month for individuals: an individual account with the complete educational library and basic wellness content. Professional is $29.99/month, built for trainers, physical therapists, chiropractors, physicians, athletic trainers, coaches and wellness providers, and the plan under which the team features are being built: multiple staff logins, organization workspace, shared collections, presentation mode and priority support. Every one is labelled “Coming Soon” and none is available yet, so today Professional unlocks the same library as Personal. The interactive 3D atlas is free for everyone, and you can cancel anytime.
How accurate is the anatomy?
Content is written against established anatomical references and carries an honest review status on every record. Everything is currently authored and awaiting clinical review. No record is marked 'verified' until it has final sign-off, and the badge on each structure tells you exactly where it stands. We would rather show our working than overstate it.
Who is Momentum built for?
Students, patients, athletes, movement and healthcare professionals, and anyone curious about how their body works. It's designed to be understood without a medical background.
Will more anatomy be added?
Yes. The library grows continuously as structures are authored and reviewed. Momentum is early: the interactive body already covers the whole figure, and the written depth behind it expands over time.
How often is new content released?
Momentum is pre-launch, so content is added continuously rather than on a fixed schedule. We'd rather ship reviewed content when it's ready than promise a cadence we can't keep.
Are educational videos included?
Not yet. Videos are in production and will be part of Premium as they're released. We don't list content that doesn't exist; when videos are live, you'll see them here.
Can I cancel my membership anytime?
Yes. Any membership (Personal or Professional) can be canceled at any time from your account's billing portal. Your access continues to the end of the current billing period, and it does not renew after that.
Will AI features be added later?
That's on the roadmap: guided answers grounded in the same cited evidence behind the library, so you can ask a question and get an explanation that points back to real sources. It isn't available today, and we'll keep saying so until it is.
Our standards
We'd rather show our working.
Momentum is coming soon, built for athletes, coaches, clinicians and active people. We have no adoption numbers to boast about and no reviews to quote, so here is what we can actually show you instead.
852
anatomical records
Muscles, bones, nerves, joints, conditions and movements: each one a page you can open and read.
7
reference works
Clinical claims cite one of them, or the field is left empty. We don't fill gaps with plausible-sounding text.
0
marked verified
No record is yet marked verified (our highest bar, requiring final sign-off). Every page tells you exactly where it stands.
We've also answered 471 of the questions people actually ask about their bodies. When we don't know, the page says so, and it grows as the evidence and the review do, not as marketing needs it to.
