📖 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.

Gluteus Medius

Fan-shaped muscle on the lateral pelvis. Comprises four anatomical compartments with differential functions. Primary hip abductor and pelvic stabilizer during initial gait phase.

Draft95%

Anatomy

Origin: Gluteal fossa (between anterior and posterior gluteal lines), gluteal aponeurosis, posteroinferior edge of iliac crest
Insertion: Lateral and superoposterior facets of greater trochanter via lateral and posterior tendon parts
Action: Anterior fibers: abduction and internal rotation; middle fibers: abduction; posterior fibers: abduction and external rotation; primary hip stabilizer during initial gait phase and pelvic rotation
Innervation: Superior gluteal nerve (L4-S1) with 3-4 branches supplying different muscle regions
Blood Supply: Superior gluteal artery
