description: >-
  Every enumerated value in the Free Exercise DB record schema. These are the exact
  enum members published in the provider's own schema.json (JSON Schema draft-04) and
  are the only legal values for the corresponding fields. Counts are observed across
  the 873 records in dist/exercises.json.
notes: >-
  force, mechanic and equipment additionally permit null — the provider's README states
  these three fields are incomplete in some records, which is why null was admitted to
  the enum rather than the field being made optional.
