📖 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.

Wrist Deviation Exercise (Radial/Ulnar)

Draftstrength80%beginner⬤ limited evidence
View FHIR resourceFHIR R4 ActivityDefinition — the interoperable form of this exercise

Positions & Range of Motion

Start
seated, forearm resting along the thigh in thumb-up (neutral) rotation, wrist and hand hanging just off the knee/edge holding a light dumbbell, wrist in neutral alignment
End
hand swept up into radial deviation (thumb side toward the ceiling), then reversed down into ulnar deviation (pinky side toward the floor), forearm unmoving
Range of Motion
radial deviation ~0–20° and ulnar deviation ~0–30° from neutral; motion isolated to the wrist with the forearm and elbow held still

How to Perform

Seated with forearm on thigh, wrist hanging off edge. Move wrist side to side with light weight. Targets wrist deviators used in gripping and tool use.

Evidence-Based Dosing & EMG Data

Recommended Dosing

3×10-15 reps each direction with light weight

Muscles Involved (4)

Primary Movers

Flexor Carpi Radialis— Radial deviation
Extensor Carpi Radialis Longus— Radial deviation
Flexor Carpi Ulnaris— Ulnar deviation
Extensor Carpi Ulnaris— Co-primary for ulnar deviation with FCU

Easier Variations ↓

1

No Weight

Perform without weight, focusing on range of motion.

Harder Variations ↑

1

Hammer Deviation

Hold a hammer by the end — the offset weight increases resistance through deviation range.

2

Progress to wrist-resistance-6-direction

AUDIT: The 6-direction node's notes state it consolidates isolated wrist-deviation exercises; expanding from 2-direction deviation to the full 6-direction protocol is a genuine harder variant.
