Under-Jaw Finger Shelf Lift

Sit tall at an eye-level mirror. Soften the shoulders and unlock the jaw. Slide both hands under the jaw so the flat fingers meet at the chin center beneath the jawline — match the cover. Point thumbs upward along the mandible without digging into the throat. Give a light upward shelf intent about 2/10 while the chin stays level. Hold four seconds, then release two seconds. Complete eight holds. Never crank the neck back or press into the windpipe.

• Primary — Soft proprioceptive cue for the submental shelf and platysma under-jaw line via light upward finger feedback; not a deep digastric mash.
• Neighbors — Suprahyoid soft tissue may feel a gentle lift intent; masseter stays quiet with teeth lightly apart.
• Hand cue — Flat fingers meet under the chin center; thumbs up along the mandible like the cover.
• Contrast — Chin Fist Rest uses a fist under a level chin; Midline Chin Index uses one finger; Neck Tilt tips the head back with no hands.
• Keep quiet — Upper trapezius hike, corrugator frown, and hard teeth clench. Calm level gaze like the cover is the standard.

Mirror at eye level. Shoulders down. Set the flat finger shelf under the jaw with thumbs up before any hold — match the cover.

Inhale as the finger shelf settles under the jaw. Exhale during the four-second quiet upward intent. Keep the chin level — no neck crank.

• Eye-level mirror
• Clean hands

1. Cup both hands under the jaw so flat fingers meet at the chin center — match the cover.
2. Point thumbs upward along the mandible with pressure about 2/10.
3. Hold four seconds with a quiet upward shelf intent, then release two seconds.
4. Complete eight holds without pressing the windpipe or tipping the head back.

• Resting on a fist like Chin Fist Rest Press
• Using one index only like Midline Chin Index Cue
• Digging thumbs into the throat
• Tipping the head back to “help” the lift

• Beginner: 5 holds of 3 seconds, almost hovering
• Standard: 8 holds of 4 seconds as coached
• One-side focus: match pressure left and right under the jaw
• Cool-down: chin tuck to neutral for two breaths

• Rest the hands; stack the head over the spine for three breaths
• Optional gentle chin tuck to neutral
• Roll the shoulders back once
• Do not stack another hard jaw isometric next

• Builds clearer submental shelf awareness at a desk
• Offers a stable bilateral under-jaw landmark
• Pairs well after forward-head posture resets
• Helps interrupt a forgotten chin–neck line habit

• People who lose chin–jaw awareness at a desk
• Beginners wanting a clear bilateral under-jaw landmark
• Anyone pairing jaw work with better head stacking
• Men and women — jaw width varies; the finger-shelf cue stays

• Acute cervical strain or throat tenderness
• Early days after submental procedures until cleared
• Anyone advised against anterior neck pressure
• Positional dizziness when adding any head tilt

• Pressing into the windpipe or hyoid
• Tipping the head back hard like Neck Tilt Platysma Stretch
• Clenching the jaw while “helping” the lift
• Hiking the shoulders while framing the face

• Morning after waking when the chin–neck line feels soft
• Midday as a posture reset at a desk
• Evening before gentle neck work as a hand landmark
• Skip with acute neck pain or after fresh submental procedures until cleared

• During acute neck or throat pain
• Right after submental work while swollen
• When anterior neck skin is bruised or infected
