📖 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.

Ankle Eversion/Inversion Strengthening

Draftstrength85%beginner⬤ moderate evidence
View FHIR resourceFHIR R4 ActivityDefinition — the interoperable form of this exercise

Positions & Range of Motion

Start
seated with the leg extended and the shin stabilized, resistance band anchored laterally for eversion or medially for inversion, foot in neutral
End
eversion — sole swept outward (little-toe side up) to end range; inversion — sole swept inward (big-toe side up) to end range, against the band
Range of Motion
subtalar/ankle eversion 0→~15–20° and inversion 0→~20–30°, isolated at the ankle

How to Perform

Targeted strengthening of ankle evertors (peroneus longus) and invertors (tibialis anterior/posterior) with resistance band. Band is anchored laterally for eversion, medially for inversion. Prevents recurrent ankle sprains and chronic instability by targeting lateral ankle stabilizers.

Coaching Cues

  1. 1

    Quiet shin — sole rolls inward, then outward

    (verbal)
  2. 2

    Sweep the outside of the foot toward the wall

    (verbal)
  3. 3

    Sweep the inside of the foot toward the opposite wall

    (verbal)
  4. 4

    Hand on the shin keeps the leg silent

Evidence-Based Dosing & EMG Data

Recommended Dosing

3×15 reps each direction, progress resistance weekly

Muscles Involved (3)

Primary Movers

Peroneus Longus (Fibularis Longus)— Eversion — key lateral ankle stabilizer
Tibialis Anterior— Inversion component
Tibialis Posterior— Inversion and medial arch support

Easier Variations ↓

1

Active Eversion/Inversion (No Band)

Perform the motions without resistance, focusing on full range and motor control.

Harder Variations ↑

1

Standing Single-Leg Balance on Foam

Stand on one foot on a foam pad. Challenges dynamic eversion/inversion reactively.

2

Lateral Band Walks

Walk sideways with a band around the ankles. Functional eversion/inversion with hip abduction.

3

Progress to single-leg-stance-unstable

AUDIT: Progress from seated open-chain resisted eversion/inversion to reactive single-leg balance on foam/unstable surface.

Research Notes

Evidence: strengthening evertors/invertors prevents recurrent ankle sprains and chronic instability [Wu 2025, AAFP 2025]. Targets lateral ankle stabilizers.
