Welcome to the Library
May 22, 2026 · Shade
Why we're building a free, evergreen home for performance knowledge, and what to expect from this blog.
The Library is where we explain how to train from first principles: training theory, programming, physiology, and discipline-specific guides. It's free to read, evergreen, and updates when the science does.
This blog is the other half: timely pieces, deeper dives, and the occasional opinion. Where the Library is reference, the blog is conversation.
What you'll find here
- Deep dives that go further than a reference page should.
- Practical breakdowns of how a principle plays out in a real program.
- Notes from the field: what we're learning as people train with the app.
If you're brand new, start with Basics of Training in the Library, then come back here when you want to go deeper.
