📖 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.
Adductor Magnus
Largest adductor with two functionally distinct portions: adductor portion (anterior) and hamstring portion (posterior). Dual innervation in >90% of cases.
Draft95%
Anatomy
- Origin
- Adductor portion: inferior pubic ramus and ischial ramus; Hamstring portion: ischial tuberosity
- Insertion
- Adductor portion: linea aspera; Hamstring portion: adductor tubercle of femur
- Action
- Adduction; adductor portion also flexes and internally rotates; hamstring portion extends and externally rotates
- Innervation
- Dual innervation: adductor portion receives both posterior branch of obturator nerve (L2-L4) and tibial portion of sciatic nerve (L4-S1) in >90% of cases; hamstring portion receives tibial nerve
- Blood Supply
- Medial circumflex femoral artery, perforating branches of profunda femoris
