Building Your Athlete OS: The Advanced Series
Give your AI coach a brain, a 3D command center, its own website, and a way to text you back.
The 7-Day Challenge gets your Athlete OS running on your laptop. The Advanced Series takes it into your everyday life. Here's every lesson in one place.
Athlete Brain: Claude + Obsidian
The preview that started it all: giving your Athlete OS a living, changing brain you can draw real insights from, built with Claude and an Obsidian vault.
Lesson 1: Give Your Athlete OS a Brain
Your AI coach is only as good as how your data is organized. This lesson turns everything you've built into a connected wiki vault: your whole training history, structured, tagged and linked so your AI can remember all of it.
The result is far better answers. Instead of reacting to your last few runs, it reasons over years of your real data, and the more you feed it, the sharper it gets.
Lesson 2: Link Your Brain to Your Dashboard
Remember the dashboard from Day 7? This lesson brings it to life. Your whole Athlete OS becomes a glowing 3D brain in the browser: your brand at the center, every note orbiting it, all in your colors.
Your coach skills become buttons that actually run.
You can chat with your OS, and it answers with your whole training history.
It works on your phone.
Lesson 3: Launch Your First Website
Lesson 2 built your command center on your laptop. Lesson 3 gives it an address on the internet:
Put it online behind a login screen that matches your app.
Get your own URL to pull up training stats and workouts from anywhere.
GitHub and Vercel handle hosting, and Claude Code does the technical parts.
Lesson 4: Your Personal Fitness Agent
The final lesson: text your Athlete OS from your phone, anywhere in the world, and it texts back. The brain is alive.
