Why GymCoach? It is the only workout tracker you self-host that brings your own LLM. Log your training, see your progress, and get a coach that actually knows your data: weekly debriefs, a streaming chat, and full programs generated from a sentence. Your data stays in your database; the AI runs on your Anthropic or OpenRouter key.

Status: actively developed. Multi-user, provider-agnostic (Anthropic or OpenRouter), with a unit / integration / E2E test suite and deep AI integration.

This repo largely maintains itself

GymCoach is also an experiment in autonomous software maintenance: most of its ongoing changes are made by Claude
