Is the exercise API reliable and how is the media delivered?
WorkoutDB is a first-party hosted API, so there is no aggregator in the request path, and all media is delivered over a CDN — meaning fast, geographically consistent video, GIF, and photo loads for your users.
Why first-party + CDN matters
When an exercise API is resold through a marketplace, you inherit an extra hop, extra latency, and a second point of failure. WorkoutDB is the source: you call the API directly, which keeps the contract stable and the path short.
Media is the heavy part of any fitness app, so every video, GIF, and photo is served from a CDN with stable URLs you can cache. Combined with caching exercise data on your side — it changes rarely — you get a fast experience without hammering the API.
- First-party API — no marketplace middleman in the request path.
- Video, GIF, and photos served over a CDN with stable URLs.
- Near-static data caches well, reducing load and latency.
- Predictable { data, meta, requestId } responses for easy retries.
