  • 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.

Pelvic Clock Mobilization

Why Include This

The pelvic clock teaches conscious, graded control over the anterior/posterior and lateral pelvic tilts that underlie neutral-spine positioning, hip-hinge mechanics, and load transfer through the lumbopelvic region. Many people move the pelvis and lumbar spine as a single rigid block; segmenting the motion into small, isolated tilts builds proprioceptive awareness and the ability to find and hold a neutral pelvis on demand — a prerequisite skill for bracing, hinging, and most corrective programs. Honest evidence note: the drill originates from Feldenkrais/motor-control traditions and is widely used clinically, but high-quality trials isolating the pelvic clock itself are lacking. The supporting evidence is largely mechanistic and expert-opinion, extrapolated from the broader (still mixed) literature on lumbopelvic motor-control exercise for low back pain. It is best framed as a low-risk awareness and mobility primer rather than a treatment with proven specific effects.

Evidence basis: expert-opinion

Positions & Range of Motion

Start
Supine (hooklying): lying on the back with knees bent, feet flat on the mat about hip-width apart, arms resting at the sides, and the pelvis in a relaxed neutral position.
End
Returns to the same neutral supine hooklying position after completing the circles; the pelvis settles midway between the 12 and 6 o'clock tilts.
Range of Motion
Small, sub-maximal pelvic tilt in all directions — roughly a few degrees of anterior/posterior and lateral tilt (typically well under 10-15 degrees each way). The lumbar spine moves through only a small portion of its available flexion/extension and lateral flexion; deliberately kept minimal to emphasize control over range.

Coaching Cues

  1. 1

    Picture a clock face resting flat on your lower belly, 12 toward your ribs and 6 toward your pubic bone. Roll the pelvis to point at each number.

    (external)
  2. 2

    At 12, gently flatten your low back into the mat; at 6, let a small arch appear under your low back. Keep both motions tiny and painless.

    (internal)
  3. 3

    Move slowly and continuously — imagine the second hand sweeping the circle rather than clicking between numbers.

    (tempo)
  4. 4

    Keep your ribs, shoulders, and legs quiet; only the pelvis should move. If your whole trunk rocks, make the motion smaller.

Evidence-Based Dosing & EMG Data

Recommended Dosing

1-2 sets of 5-8 slow circles in each direction (or 8-10 controlled tilts per direction for the two-point version), once daily or as a warm-up/awareness primer before core and hip-hinge work. Motion should be small, smooth, and pain-free; quality over quantity.

EMG Activation Data

No specific surface-EMG validation exists for this drill; muscle roles listed are mechanistic/anatomical inferences rather than EMG-confirmed activation levels.

Muscles Involved (9)

Primary Movers

IliopsoasProduces the anterior tilt (6 o'clock) as the pelvis rolls forward and the low back arches.
Rectus AbdominisDrives the posterior tilt (12 o'clock), flattening the low back into the mat.

Stabilizers

Transversus AbdominisProvides low-level deep core support so the tilts stay small and controlled rather than gross trunk movement.
MultifidusSegmental lumbar stabilizer that helps grade the fine anterior/posterior motion.

Synergists & Assistors

Quadratus LumborumSynergistInvolved in the lateral (3/9 o'clock) hiking component of the pelvic tilt.
Gluteus MaximusSynergistLightly assists the posterior tilt; kept relaxed so the drill stays a control task, not a squeeze.
Erector Spinae GroupSynergistAssists the anterior tilt and lumbar extension component; lengthens during the posterior tilt.
External ObliqueSynergistContributes to the 3 and 9 o'clock lateral tilts and to smoothing the circular tracing.
Internal ObliqueSynergistPairs with the external oblique to control lateral pelvic tilt side to side.

Easier Variations ↓

1

Two-point rock (12 and 6 only)

Work only the anterior/posterior tilt between 12 and 6 o'clock, skipping the sides, until the front-to-back motion feels smooth and isolated.

2

Assisted awareness with hands

Rest your hands on the front of the pelvis (on the two hip bones) to feel the tilt directly, using the tactile feedback to sense direction before removing the hands.

Harder Variations ↑

1

Full circle both directions

Trace the complete clock smoothly clockwise, then counterclockwise, aiming for an even circle with no flat spots or skipped hours.

2

Upright pelvic clock (seated or standing)

Perform the same clock pattern seated on a stool or standing against gravity, carrying the control skill into functional, weight-bearing positions.
