OpenGym.
A plan for the next session.
A self-hosted workout and body-weight tracker, extended with saved workout plans and weekly meal planning.
Make room
for movement.
What it makes possible.
Build on OpenGym’s workout tracking with reusable training plans and weekly menus that can be reviewed and adjusted before use.
- Upstream: workout and body-weight tracking, guided sessions, an exercise catalogue and sync across devices.
- I added six curated workout families, saved plans and preview-before-activation.
- Meal preferences and dietary exclusions guide a weekly menu, with ingredient details and estimated nutrition.
- Seven-day plans, exclusions, meal swaps and grocery lists using 96 ingredients, 40 meals and 12 snacks.
Under the surface.
- 01
React and Zustand manage the interface and application state.
- 02
A native Node.js HTTP service and JSON storage support authenticated use; guest use works offline.
- 03
A PWA and Capacitor shell support installation. Meal plans are generated in the browser from curated rules and attributed nutrient data, so this feature also works offline.
The deliberate choices.
- Use deterministic local planning without adding an AI server dependency.
- Show a plan before activation and allow meal substitutions.
- Treat nutrient values as estimates with provenance.
Where it stands.
Implemented workout and nutrition planning extensions in a fork. Release review is ongoing, so outbound promotion links are withheld. No upstream exercise media is copied into this portfolio.
