Free Exercise DB

Free Exercise DB is an open, public-domain exercise dataset published by yuhonas on GitHub: 873 individual JSON documents describing strength, stretching, plyometric, powerlifting, olympic-weightlifting, strongman and cardio exercises, each with a stable id, name, difficulty level, force and mechanic classification, required equipment, primary and secondary muscle groups, step-by-step instructions and demonstration images. Every record validates against a published JSON Schema (draft-04) that also acts as the project's controlled vocabulary for muscles, equipment and categories. There is no REST API and no OpenAPI: consumption is by unauthenticated HTTPS GET of the combined dist/exercises.json array (or of a single exercise document) from raw.githubusercontent.com, with images served from the same host. A Vue.js browsable/searchable frontend is published to GitHub Pages. The whole dataset is released under the Unlicense.

Free Exercise DB publishes 1 API on the APIs.io network. Tagged areas include Company, Open Data, Fitness, Exercise, and Health.

Free Exercise DB’s developer surface includes documentation, API reference, getting-started guide, support, authentication, and 12 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Health regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/.
