📖 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.

Scapular Downward Rotation Control (Arm Lowering)

Draftmotor-control75%beginner⬤ limited evidence
View FHIR resourceFHIR R4 ActivityDefinition — the interoperable form of this exercise

Positions & Range of Motion

Start
standing with the arm elevated overhead, long spine and quiet shoulder, free hand on the shoulder blade
End
arm slowly lowered along an arc down to the back hip pocket over ~4 seconds, scapula eccentrically downwardly rotating and gliding smoothly
Range of Motion
controlled eccentric arm lowering from overhead to hip with scapular downward rotation through available range

How to Perform

Controlled arm lowering from overhead emphasizing eccentric scapular downward rotation. Rhomboid major 25-45% MVIC, levator scapulae 25-58% MVIC. Clinically relevant for hand-behind-back movements. Downward rotation is primarily addressed through controlled mobility rather than strengthening.

Coaching Cues

  1. 1

    Quiet shoulder, long spine — eccentric lives in rhomboids

  2. 2

    Lower the hand along an arc to the back hip pocket

    (verbal)
  3. 3

    Take 4 slow seconds to bring the arm down

    (verbal)
  4. 4

Evidence-Based Dosing & EMG Data

Recommended Dosing

3×10 reps slow arm lowering (3-5 second eccentric), 2-3x/week

Muscles Involved (3)

Primary Movers

Rhomboid Major— 25-45% MVIC — primary downward rotator [Berckmans 2021]
Levator Scapulae— 25-58% MVIC — assists downward rotation [Berckmans 2021]

Stabilizers

Lower Trapezius— Eccentric control during lowering

Easier Variations ↓

1

Wall Slide Down

Perform against a wall for tactile feedback during the lowering phase.

Harder Variations ↑

1

Weighted Arm Lowering

Hold a light dumbbell. Eccentric control with external load.

Research Notes

Downward rotation is less commonly trained. Addressed through controlled mobility and eccentric control [Berckmans 2021].
