📖 Static demo — read-only snapshot
You’re browsing a static build of the Body IQ knowledge graph, so everything loads with no backend. A few things that need the live server are turned off here:
- Global search (sidebar) is disabled — it queries the API.
- The JSON API and the API “Try it” playgroundaren’t included.
- The data is a snapshot — it refreshes only when the demo is rebuilt, not live from the database.
Everything else — the body map, progression ladders, coverage heatmap, exercise finder, and all anatomy/exercise/source pages — works fully. The full app (live search + API + database) runs from the source on GitHub.
Supinator
Deep forearm muscle. Supinates the forearm, especially during slow movements.

Anatomy
- Origin
- Lateral epicondyle of humerus, supinator crest of ulna
- Insertion
- Lateral surface of proximal radius
- Action
- Forearm supination
- Innervation
- Deep branch of radial nerve (C5, C6)
- Blood Supply
- Radial recurrent artery
Movements (2)
| Movement | Joint | Role | Notes |
|---|---|---|---|
| Forearm Supination | Proximal Radioulnar Joint | Primary | Primary when elbow is extended |
| Elbow Flexion | Humeroulnar Joint | Stabilizer | Maintains supination during flexion |
Exercises (5)
| Exercise | Role |
|---|---|
| Forearm Pronation/Supination with Hammer | Primary |
