Chin Tucks

Deep cervical flexor activation, forward head posture correction

Minimum Effective Dose
40s
The shortest time that still creates real, measurable change. Hit the dose and the benefit starts. Everything after is bonus.

Why it works

Chin tucks activate the deep cervical flexors, which are the muscles that counteract forward head posture. The Jull protocol (10 reps x 5s hold) is the research-backed standard for cervical stabilisation.

How to do it

Double chin. Hold gently.
Draw the chin straight back, not down. Feel the back of the neck lengthen. Hold 5 seconds, release.
