My fork of the JSON (800+) Exercise Dataset by yuhonas that I use in my training app LogOut.

What do they look like?

All exercises are stored as seperate JSON documents and conform to the following JSON Schema. Here’s an example :

{
  "id": "alternate_incline_dumbbell_curl",
  "name": "Alternate Incline Dumbbell Curl",
  "force": "pull",
  "level": "beginner",
  "mechanic": "isolation",
  "equipment": "dumbbell",
  "primaryMuscles": [
    "biceps"
  ],
  "secondaryMuscles": [
    "forearms"
  ],
  "instructions": [
    "Sit down on an incline bench with a dumbbell in each hand being held at arms length. Tip: Keep the elbows close to the torso.This will be your starting position."
  ],
  "category": "strength",
  "images": [
    "alternate_incline_dumbbell_curl/0.jpg",
    "alternate_incline_dumbbell_curl/1.jpg"
  ]
}

See Alternate Incline Dumbbell Curl JSON file.

To further explore the data, you can use datasette.

How do I use them?

Main combined DB exercises.json, translated name and instructions DBs exercises.<language>.json and translated enums DB i18n.json are available through GitHub Releases.

For images, you can leverage GitHub's hostinge prefixing image path's contained in JSON with https://raw.githubusercontent.com/gfauredev/free-exercise-db/main/exercises/, eg. air_bike/0.jpg.

Build tasks

There are a number of helpful justfile tasks that you can use.

Linting & Check

To lint all the JSON files against the schema.json use

just lint

To check for non-unique IDs, use

just check

Combining into a single JSON file

If you make changes to any of the exercises or add new ones, recombine all single JSON files into a single JSON containing an array of objects, using the build just task

just build

Importing into PostgreSQL

To combine all JSON files into Newline Delimeted JSON suitable for import into PostgreSQL use the following just task

just build-ndjson
