📖 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.

Side Plank with Hip Abduction

Draftmotor-control80%intermediate⬤ moderate evidence
View FHIR resourceFHIR R4 ActivityDefinition — the interoperable form of this exercise

Positions & Range of Motion

Start
established side-plank position on the down forearm, hips lifted into a straight head-to-heel line, top leg stacked on the bottom leg
End
top leg lifted into hip abduction with the heel reaching toward the ceiling while the side-plank line is maintained, then lowered under control
Range of Motion
hip abduction ~0–30° of the top leg superimposed on a sustained isometric side-plank hold

How to Perform

Side plank with top leg performing hip abduction. Standard side plank produces highest lumbar ES among plank variations. Adding abduction increases glute med demand (54.9-81.9% MVIC range). Distinct from Copenhagen plank (which is adduction). May not be tolerated in acute LBP.

Evidence-Based Dosing & EMG Data

Recommended Dosing

3×8-12 reps per side, or isometric 3×15-30s holds

EMG Activation Data

Side plank: highest lumbar ES [Calatayud 2017]. Glute med 54.9-81.9% MVIC unilateral exercises [Mausehund 2019]

Muscles Involved (6)

Primary Movers

Gluteus Medius— Hip abduction against gravity
Quadratus Lumborum— Lateral trunk stability

Secondary Movers

External Oblique
Internal Oblique

Stabilizers

Erector Spinae Group— Highest among plank variations [Calatayud 2017]

Lengthened / Stretched

Adductor Group (Longus/Brevis/Magnus)— AUDIT: Top-leg abduction lengthens that leg's adductors as passive antagonist.

Easier Variations ↓

1

Knee Side Plank

Bottom knee on ground, no abduction.

2

Sidelying Hip Abduction

Remove plank — isolate glute med.

3

Regress to hip-abduction-strengthening

AUDIT: Drop the plank and regress to floor-based side-lying abduction if the bridged position is not tolerated.

Harder Variations ↑

1

Side Plank with Band

Band above knees for increased resistance.

2

Side Plank with Rotation

Add trunk rotation between abduction reps.
