Lateral Neck Flexor Stretch (Side Tilt)

How to do it

1. Sit (or stand) and place the right hand on the left shoulder to hold it down (or grasp the chair seat to hold shoulders level).
2. Tilt the head directly sideways toward the right to stretch the left lateral neck flexors.
3. For added stretch, give assistance with the opposite hand by pulling the forearm gently downward.
4. Reverse hands and head position to stretch the right side.

Form cues

• Hold the down-side shoulder down so the stretch is at the neck
• Tilt directly sideways - do not rotate

Why this exercise helps

The upper trapezius, scalenes, and neighboring lateral neck muscles contribute to side-bending and control of the head and shoulder area. Anchoring the opposite shoulder while tilting the head directly sideways reduces the tendency to shrug and can create a clearer stretch along the side of the neck. The assisting arm adds only light guidance; it should not force the neck farther. Practicing both sides through a comfortable range can support neck-mobility work, but the exercise does not diagnose which muscle is responsible for a head or shoulder asymmetry.

Stop or modify if

• Allowing the opposite shoulder to shrug upward, which redirects the stretch away from the neck.
• Rotating or jutting the chin forward instead of tilting the head directly sideways in a pure lateral direction.
• Pulling the head with the assisting hand rather than providing a gentle guided pull on the forearm.

Modifications and progressions

• Omit the assisting arm pull and hold only the passive side-tilt if the neck is sensitive or the added force feels excessive.
• Grasp the seat edge with the down-side hand to anchor the shoulder without needing a separate hand-on-shoulder technique.
• Stop for dizziness, headache, visual change, numbness, tingling, or symptoms travelling into an arm.
