📖 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.
Active Hallux Extension (Big Toe Lifts)
Positions & Range of Motion
- Start
- seated (or standing) with the foot flat on the floor, all five toes resting down
- End
- big toe (hallux) lifted/extended to end range while the lesser four toes stay pressed firmly into the floor, held 3 s at the top
- Range of Motion
- isolated first-MTP extension from 0° to comfortable end range (~50–70°); lesser toes held at 0° (no motion)
How to Perform
Sitting or standing with feet flat. Lift ONLY the big toe (hallux) while keeping the lesser four toes pressed firmly into the floor. Hold 3 s at top. Distinct from toe yoga's alternating drill — this is hallux-isolated extension training for first-MTP function.

Research Notes
Targets functional hallux limitus. Strong correlation between active weight-bearing hallux dorsiflexion and gait first-MTP motion (r = 0.80). Standard prerequisite for plantar fascia, hallux valgus, and gait-mechanics rehab.
