For Pilates teachers, yoga teachers, massage therapists & trainers
Learn your muscles. Actually remember them.
Every anatomy course you've tried felt like it was written for a medical student. This one wasn't. 79 lessons. 65 muscles. Taught in 3D.
See it move. Understand it. Keep it.

Anatomy you can actually use in the room.
Every other resource
Flat diagrams. Dense text. Forgotten by Friday.
Most anatomy books and courses are built for people studying to become doctors — not for the Pilates teacher who needs to cue a client's hip flexors precisely, the yoga teacher working out why a student's hamstring keeps pulling, or the massage therapist who needs to know exactly where the psoas attaches.
The information is there. But it never sticks.
3D Muscle Lab
See it move. Understand it. Keep it.
Every muscle is taught in 3D — you see exactly where it sits, where it attaches, and what happens when it contracts. Then the quiz system reinforces it until it's genuinely in long-term memory.
Not memorized for a test. Actually known.
How each lesson works
Four steps. One muscle. Locked in.
- 01
Bony landmarks
Before the video, you preview the attachment points on the skeleton. Try to recall where the muscle attaches before opening each toggle. That retrieval attempt is the first layer of memory work.

- 02
Watch the lecture
David walks through origin, insertion, action, and clinical relevance — with the 3D model on screen the whole time. Plain language. No unnecessary jargon.

- 03
Look, listen, read
Each muscle gets its own 3D image with audio narration. Look at the model, listen, and read at the same time. Three input channels at once — retention goes up significantly.

- 04
Test yourself
Multiple quiz styles — recall, recognition, image-based — reinforce the material in different ways. This is what separates knowing a muscle from having read about one.

12 modules. 79 lessons. 15 hours.
The course works joint by joint through the whole body. Every muscle is covered twice — once for its bony landmarks, once for its attachments and actions — and every module ends with a quiz. Click any module to see what's inside.

David Keil — M.S. Exercise Physiology, LMT, NMT
Kinesiology was the first course I taught, back in 1999, at a massage school in Miami. I was immediately confronted with the real problem: taking a genuinely complex subject and making it land for students from every walk of life — dancers, athletes, career changers, people who hadn't opened a science textbook in twenty years.
I've spent the years since teaching functional anatomy to movement professionals around the world, and writing Functional Anatomy of Yoga to do the same thing in print: take the complexity out without dumbing the content down.
"I kept meeting brilliant practitioners who were held back by anatomy resources written for medical students. I built this course because seeing a muscle move in 3D is worth more than any diagram."
From practitioners like you
What happens when anatomy finally clicks.
"Before 3D Muscle Lab, I couldn’t make muscles, their attachments, and the related actions come alive in my mind’s eye. I could only find flat pictures with words, words, words. 3D Muscle Lab showed me the body moving and how the muscles are attached. It all comes alive and makes sense."
"I used to have headaches just trying to learn the names and terminology. David’s instruction is so clear. Even for someone like me who speaks Spanish and not much English — I could understand the whole program. Learning anatomy couldn’t be easier."
For teacher training programs
Running a Pilates teacher training? There’s a version of this for you.
If you run a Pilates or movement teacher training, you can license this course for your students instead of building an anatomy module yourself. Pre-recorded, self-paced, and quizzed at every stage — the format certifying bodies permit for anatomy. Programs in the US, Mexico, Germany, and Australia already run it.
