ChatGPT meets HIIT Science: Athletica’s New AI Coach | Athlete’s Compass

In this episode of The Athlete’s Compass, the team introduces Athletica’s newly launched AI coach—an intelligent training assistant that combines large language models (LLMs) with athlete-specific data like HRV, sleep, and training load. Unlike generic AI tools, this coach taps into the HIIT Science textbook and contextualizes advice based on six weeks of an athlete’s training history. Paul Laursen, Marjaana Rakai, and Paul Warloski walk through how it works, what sets it apart, and demonstrate its capabilities in real-time. The conversation highlights not only the tech’s sophistication but its potential to empower athletes and coaches alike through contextual, science-backed decision-making.

Key Takeaways
AI + Personal Data = Precision Coaching: The AI coach analyzes training data like HRV, heart rate, and sleep to give context-aware, real-time advice.
HIIT Science Textbook is Embedded: It doesn’t guess—its responses are backed by content from The Science and Application of High-Intensity Interval Training.
Real-Time Scenarios: Whether you're sick, tapering, or targeting a hilly Ironman, the AI provides personalized strategies.
Built-In Guardrails: It won’t override your training plan but will suggest appropriate tweaks based on your context.
For Coaches Too: While not yet multi-athlete enabled, future updates will allow coaches to use it across their roster.
Customization: Users can adjust the coach’s personality (casual/professional) and depth (plain language to sports science level).
AI Agent Architecture: It uses Retrieval-Augmented Generation and purpose-built agents (e.g., for recovery or training load optimization).
More Than a Chatbot: Unlike ChatGPT, this coach knows your actual training history and adjusts accordingly.
