📖 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.

Chin Tuck with Overpressure

Draftmobility80%beginnermoderate evidence
View FHIR resourceFHIR R4 ActivityDefinition — the interoperable form of this exercise

Positions & Range of Motion

Start
seated tall with a neutral spine, head in neutral, two fingers placed lightly on the chin
End
chin drawn straight back into craniocervical retraction/flexion until the back of the neck lengthens, held ~3 s with gentle finger overpressure
Range of Motion
cervical retraction (craniocervical flexion) from neutral to comfortable end range, no downward nod

How to Perform

Sitting tall, place 2 fingers on the chin and gently press the chin straight back (not down) until you feel the back of the neck lengthen. Hold 3 seconds.

Coaching Cues

  1. 1

    Chin moves straight back, not down — "double chin" cue

    (verbal)
  2. 2

    Stop pressure when the back of the neck lengthens; don't force

    (verbal)

Evidence-Based Dosing & EMG Data

Recommended Dosing

8 reps × 3-second hold, 1–2×/day.

Muscles Involved (6)

Primary Movers

Deep Cervical FlexorsLongus colli/capitis are the agonists driving craniocervical flexion and the 'chin straight back' retraction — the muscle being trained; overpressure assists rather than replaces the contraction.

Lengthened / Stretched

Suboccipital MusclesUpper-cervical extensors directly stretched as the base of the skull nods and the back of the neck lengthens under overpressure.
Semispinalis CapitisPosterior cervical extensor lengthened by retraction/upper-cervical flexion.
Splenius CapitisPosterior cervical extensor stretched as the head glides back and nods.
Levator ScapulaeUpper cervical (C1-C4) attachment placed on stretch with retraction/flexion — a secondary stretch target.
Upper TrapeziusPosterior neck extensor lengthened as the cervical spine straightens and the chin tucks back — a secondary stretch target.

Research Notes

Overpressure variant of basic chin tuck; deepens deep cervical flexor activation.
