API reference

Rich exercise data

Every exercise carries muscles, equipment, category, difficulty, movement pattern, mechanics, plane of motion, laterality, media, aliases, and tags — not just a name and a picture.

Built for local caching

Sync endpoints return only what changed since your last sync, with tombstones for deleted and deprecated records. Your app stays fast offline.

Relationships that matter

Variations, progressions, and regressions are first-class. Build a programme that scales up or down with one request.

Honest rate limits

Quotas are per API key and reset daily. Every response tells you what is left, and a 429 tells you exactly when to retry.
