📖 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.

Pursed-Lip Diaphragmatic Breathing

View FHIR resourceFHIR R4 ActivityDefinition — the interoperable form of this exercise

Positions & Range of Motion

Start
Seated upright, shoulders relaxed, one hand may rest on the belly, neutral spine
End
Slow nasal inhale with the belly rising, then a quiet pursed-lip exhale (lips as if cooling soup) for twice the inhale duration, belly falling
Range of Motion
Isometric posture — minimal joint excursion; movement limited to diaphragmatic belly rise/fall and rib expansion

How to Perform

Inhale slowly through the nose, then exhale through pursed lips (as if cooling soup) for twice the inhale duration. Combine with diaphragmatic mechanics — belly rises on inhale, falls on exhale.

Coaching Cues

  1. 1

    The exhale should be quiet — purse just enough to slow airflow, not strain

    (verbal)
  2. 2

    Shoulders stay relaxed; no upper-chest lift

Research Notes

Standard COPD breathing retraining technique. Useful for wind players to develop sustained breath control and reduce accessory muscle dependence.
