Learn anatomy, movement, and personal training — the evidence-based way.
A structured path from the absolute basics to certification-ready understanding. Built for careful learners who want to know why, not just what.
Browse every lesson, muscle, and exercise. Accounts, saved progress, and quizzes live in the full app — see the GitHub link above.
Evidence-based
Every lesson, muscle, and quiz answer links to authoritative sources — OpenStax, MedlinePlus, CDC, and official guidelines.
Understand, don't memorize
Concepts are taught through reasoning and connections, in clear simple English, with pronunciation help for technical terms.
Quizzes & mastery
Original questions with full explanations. Spaced repetition resurfaces what you get wrong until you truly master it.
Personal progress
Your own account, learning path, and private history. Track completion, accuracy, and certification-domain readiness.
Anatomy & exercises
Muscle detail pages and an exercise library that shows primary, secondary, and stabilizing muscles — never oversimplified.
Safety-first
Clear guidance on a trainer's scope of practice and when to refer to a healthcare professional.
How it works
Follow the path
Start with anatomical language and movement, then a complete body region — the shoulder.
See the evidence
Read clear explanations with citations and original diagrams, plus a vocabulary helper.
Prove it
Take quizzes, review what you miss, and watch your mastery and readiness grow.
Educational, careful, and honest
This is a learning tool, not medical advice. Content is labelled by review status, disagreements between sources are shown rather than hidden, and no proprietary certification questions are ever used.
