For 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.

Flat diagrams. Dense text. Forgotten by Friday.
Most anatomy books and courses are built for people studying to become doctors — not for the yoga teacher who needs to understand 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.
Step one
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.
Step two
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.
Step three
Look, listen, read
Each muscle gets its own 3D image with audio narration. Look at the model, listen, read simultaneously. Three input channels at once — retention goes up significantly.
Step four
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.

Taught by someone who gets your world.
David Keil has spent over 25 years teaching anatomy to yoga teachers, massage therapists, and movement professionals worldwide. He is a Licensed Massage Therapist, Neuromuscular Therapist, and the author of Functional Anatomy of Yoga — one of the most widely used anatomy texts in yoga teacher training programs globally.
"I kept meeting brilliant practitioners who were being 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."
