📖 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.

Supine Chin Tuck with Liftoff

Draftmotor-control85%beginner-intermediatestrong evidence
View FHIR resourceFHIR R4 ActivityDefinition — the interoperable form of this exercise

Positions & Range of Motion

Start
supine, head resting on the surface, throat soft, preparing a gentle chin tuck
End
craniocervical flexion maintained while the head floats a card's thickness off the floor, held ~10 s without sternocleidomastoid dominance
Range of Motion
small upper-cervical flexion plus minimal head liftoff; sustained endurance hold (~29–39 s norms)

How to Perform

Deep cervical flexor endurance exercise. Patient lies supine, performs a chin tuck (craniocervical flexion), then lifts the head slightly off the surface maintaining the tucked position. Targets longus colli/capitis endurance with minimal sternocleidomastoid activation. Normative hold times: men 38.9±20.1s, women 29.4±13.7s.

Evidence-Based Dosing & EMG Data

Recommended Dosing

5-10 reps × 10s holds, progress hold duration toward normative values, 2-3x/week

EMG Activation Data

CCF pattern activates deep cervical flexors (longus colli/capitis) with significantly less SCM activation than head-lift alone [O'Leary 2007]. Target hold: men ~39s, women ~29s [Domenech 2011].

Muscles Involved (4)

Primary Movers

Deep Cervical FlexorsLongus colli and capitis — CCF pattern targets these preferentially [O'Leary 2007]

Stabilizers

Scalene MusclesCervical stabilization during hold

Lengthened / Stretched

Semispinalis CapitisAUDIT: CCF plus added lower-cervical flexion during liftoff clearly elongates the posterior cervical extensors on the stretched/antagonist side.

Synergists & Assistors

SternocleidomastoidSynergistShould show MINIMAL activation — CCF reduces SCM contribution [O'Leary 2007]

Easier Variations ↓

1

Chin Tuck Without Liftoff

Perform the chin tuck only, pressing the back of the head into the surface. No liftoff. Builds CCF activation pattern.

2

Chin Tuck with Towel Support

Place a small folded towel under the head. Perform chin tuck with gentle head press into towel. Reduces demand.

3

Regress to deep-neck-flexor-training

AUDIT: If the patient cannot maintain the tuck during liftoff or substitutes SCM, drop to the pure CCF pattern; the liftoff's named 'Chin Tuck Without Liftoff' regression IS the deep-neck-flexor-training CCF node. Distinct roster nodes.

Harder Variations ↑

1

Extended Duration Holds

Progressively increase hold time toward normative values: men ~39s, women ~29s [Domenech 2011].

2

Chin Tuck Liftoff with Rotation

Maintain the tuck and liftoff, then add gentle rotation left and right. Adds rotational endurance demand.

Research Notes

DCF endurance norms: men 38.9±20.1s, women 29.4±13.7s [Domenech 2011]. Craniocervical flexion (CCF) component ensures preferential deep cervical flexor activation with less SCM activation compared to head-lift alone [O'Leary 2007]. AUDIT[medium]: Normative endurance hold times (men 38.9+/-20.1s, women 29.4+/-13.7s) and the CCF-vs-head-lift EMG claim are attributed to Domenech 2011 and O'Leary 2007, but the linked sources contain only Kisner and ACSM. → Add Domenech 2011 and O'Leary 2007 to linked sources. AUDIT[low]: Sternocleidomastoid is assigned role 'synergist' yet its note states it 'should show MINIMAL activation' — internally contradictory, and inconsistent with sibling CCF exercises (deep-neck-flexor-training, suboccipital-exercise, sitting-ccf-oblique-band) which correctly label SCM a 'stabilizer' to be minimized. → Relabel SCM as 'stabilizer' (muscle to keep quiet) consistent with the other CCF exercises, or if the liftoff genuinely recruits SCM, remove the 'minimal activation' note.
