openGym Launches as Open-Source Routine and Workout Tracker

Introducing openGym

openGym is a newly released, open-source workout and body-weight tracking platform designed for users who want to manage their fitness data locally or self-hosted. Available via mobile app stores and direct downloads, the project aims to provide modern routine planning without relying on third-party cloud servers, mandatory subscriptions, or telemetry.

Key Features and Capabilities

• Self-Hosted or Standalone: Users can run the platform via Docker on their own infrastructure or use standalone mobile apps locally without creating an external account.
• Comprehensive Exercise Library: Includes thousands of searchable exercises categorized by muscle groups, complete with animated demonstrations and equipment filters.
• Routine Planning: Offers starter plans such as Push/Pull/Legs and 5x5, supports flexible weekly schedules or open rotations, and accommodates advanced training styles like supersets, drop sets, and timed holds.
• Data Import and Export: Allows imports from popular trackers like Strong, Hevy, and FitNotes, alongside Apple Health weight exports, with complete data export options to CSV or JSON formats.

Smart Tools and Integrations

• Live Progression Tracking: Calculates estimated 1RM, tracks volume dynamically, and applies customizable progression rules.
• Optional AI Features: An opt-in AI coach and Model Context Protocol (MCP) server can be configured using a personal provider key (such as Anthropic, OpenAI, or Ollama) to assist with routine drafting.
• Wearable Support: Includes dedicated companion tools for smartwatches and lock-screen widgets for quick set logging.
