📖 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.

Pelvic Floor Sustained Contraction (Kegel — Endurance)

Draftmotor-control90%beginner⬤ strong evidence
View FHIR resourceFHIR R4 ActivityDefinition — the interoperable form of this exercise

Positions & Range of Motion

Start
supine, knees bent, feet flat, pelvic floor relaxed, breathing normally (progresses to sitting then standing)
End
pelvic floor contracted and lifted upward toward the head, held 6–10 s, then fully relaxed for an equal interval
Range of Motion
isometric pelvic floor lift held sub-maximally; no external joint motion — internal muscle excursion only

How to Perform

Contract the pelvic floor muscles as if stopping urine flow AND lifting the perineum upward toward the head. Hold 6–10 seconds, then fully relax for equal time. Progress hold time and positions over 12 weeks (supine → sitting → standing).

Coaching Cues

  1. 1

    Breathe normally throughout the hold — breath-holding signals you're substituting

    (verbal)
  2. 2

    If glutes or inner thighs squeeze, the contraction is wrong — relax everything else

    (tactile)
  3. 3

    Imagine drawing a blueberry up into the body, not just clenching

    (verbal)

Evidence-Based Dosing & EMG Data

Recommended Dosing

8–12 reps × 3 sets/day. Progress hold to 10 s over 12 wk.

Muscles Involved (4)

Stabilizers

Multifidus— Posterior wall of the deep-core canister; co-contracts to stabilize the lumbopelvic region during the sustained hold. Stabilizer role appropriate; not a mover here.

Synergists & Assistors

Transversus AbdominisSynergist— Deep abdominal that reflexively co-activates with the pelvic floor as part of the deep-core canister during the perineal lift. Accessory synergist — the pelvic floor (levator ani) is the true prime mover but has no slug in the roster, so it cannot be listed.
DiaphragmSynergist— Top of the canister with reciprocal timing to the pelvic floor; the 'breathe normally throughout the hold' cue targets diaphragm/pelvic-floor coordination and prevents breath-holding substitution. Synergist role appropriate.
Internal ObliqueSynergist— Lower fibers co-activate with TrA and the pelvic floor to maintain intra-abdominal/pelvic tension during the isometric hold. Reasonable accessory synergist.

Easier Variations ↓

1

Shorter Hold (3-5 s)

Build endurance from 3 s holds before progressing to 10 s.

Harder Variations ↑

1

Standing PFM Holds

Same drill in standing — adds gravity load.

2

Functional Integration

Hold during sit-to-stand, light lifting, walking.

Research Notes

Audience: postpartum, perimenopausal, general conditioning. Cochrane evidence: minimum 8 contractions × 2–10 s holds × 3×/day × 3–6 months; supervised programs outperform unsupervised. Common substitution errors: visible gluteal clenching, abdominal bracing, breath-holding (Valsalva).
