What is the best exercise database API for developers?

The best exercise database API for developers is one with complete, structured data, real media, predictable REST responses, and first-class developer tooling. WorkoutDB provides ~873 exercises with demo video and photos, an envelope-based REST contract, an OpenAPI 3.1 spec, and a TypeScript SDK.

What a good exercise database API gives you

A great exercise API is more than a list of names. You want structured taxonomy (body part, target muscle, equipment, category, difficulty), step-by-step instructions, consistent media, and search that tolerates typos and accents.

Why WorkoutDB

WorkoutDB covers ~873 exercises, each with a real demonstration video, an animated GIF, photos, step-by-step instructions, and structured fields (body part, target muscle, equipment, category, difficulty). It exposes ranked fuzzy + full-text search, combinable filters, and a GET /v1/meta endpoint that returns counts and every filterable value in one call — handy for bootstrapping your app's filter UI.

Developer tooling is first-class: an OpenAPI 3.1 spec, the @workoutdb/client TypeScript SDK on npm, and a Postman collection. The free tier gives you 5,000 requests/month with no credit card required.
