# Exercise taxonomy crosswalk: exercise databases to HealthKit and Health Connect

> Almost none of it maps. Of the 149 category, equipment, muscle and body-part terms that free-exercise-db, wger and ExerciseDB v1 publish (read 2026-11-05), only one has the same name as a HealthKit or Health Connect workout type: free-exercise-db's "stretching". Their categories are body regions and training styles (Arms, Legs, strength, plyometrics), while HealthKit and Health Connect name activities, so a name-only crosswalk leaves "strength" unmapped rather than guessing STRENGTH_TRAINING. Exercise names do slightly better: 6 of free-exercise-db's 876 match a Health Connect exercise or segment type exactly. CC BY 4.0, JSON and CSV.

## The three databases and their licenses

- [free-exercise-db](https://github.com/yuhonas/free-exercise-db): Unlicense (public domain). Its license file or README says: “This is free and unencumbered software released into the public domain.” The category, equipment and primaryMuscles enums of its JSON Schema, and the name of every exercise in dist/exercises.json.
- [wger](https://wger.de): Exercise data under Creative Commons licenses set per entry; code AGPL-3.0-or-later. Its license file or README says: “Exercise/Ingredient Data: Creative Commons (see individual entries)” The exercise categories, equipment and muscles its REST API v2 lists. Its exercises are not read here.
- [ExerciseDB v1](https://oss.exercisedb.dev): Repository LICENSE is AGPL-3.0; no separate data license found. Its license file or README says: “GNU AFFERO GENERAL PUBLIC LICENSE” The body parts, equipment and muscles of the free ExerciseDB V1 API at oss.exercisedb.dev, whose home page now carries the AscendAPI name ("Previously ExerciseDB") and says it needs no sign-up and no API key. Its exercises, and ExerciseDB v2, are not read here.

## How the crosswalk is built, and its limits

- A term is mapped only when it is a database category or an exercise name and its key equals a constant's key; key = the name lowercased with a leading EXERCISE_TYPE_ or EXERCISE_SEGMENT_TYPE_ removed and every character outside a-z0-9 removed. Equipment, muscle and body-part terms name no activity and are never mapped. nameContains lists constants whose words contain the term's words in order: a text coincidence shown for browsing, not a mapping.
- Names are matched, not meanings. A category such as "strength" or "cardio" describes many activities, so it is left unmapped even where a constant's name contains it; those constants are listed under "name contains it" for browsing, and that column is a text coincidence, never a mapping.
- Equipment, muscle and body-part terms are never mapped, because they describe how or where an exercise works, not which activity a workout session records.
- wger's and ExerciseDB's exercise lists are not read, only their category, equipment, muscle and body-part lists; ExerciseDB v2, which its documentation says is accessed through RapidAPI, is not read either.
- wger and ExerciseDB v1 were read through this site's source-snapshot workflow, because their hosts are blocked from where the site is built; each term's quote is kept in ops/sources/evidence/tools-exercise-taxonomy-crosswalk.json and re-checked against the live API.
- The generator declares how many terms each list must have and refuses to write a shorter or longer one.
