Neck Flexor And Rotational Stretch

  • Beginner
  • Isolation
  • Timed hold
  • Neck
  • Shoulders

This stretch targets the sternocleidomastoid and upper trapezius to improve cervical mobility and alleviate tension caused by forward-head posture. By combining lateral flexion with rotation, it effectively releases the deep flexors and lateral muscles of the neck.

Setup

  1. Sit or stand tall with your spine neutral and shoulders pulled down and back.
  2. Place your right hand behind your lower back or hold onto the bottom of your chair to anchor the right shoulder.
  3. Look straight ahead with your chin slightly tucked.

How to do it

  1. Gently tilt your left ear toward your left shoulder until you feel a light stretch on the right side of your neck.
  2. Slowly rotate your chin upward and toward the right, looking toward the ceiling to engage the neck flexors.
  3. Hold this position for 20-30 seconds while taking slow, deep breaths.
  4. Slowly return to the starting position and repeat on the opposite side.

Form checklist

  • Keep your shoulders level; do not let the anchored shoulder shrug upward.
  • Move slowly and smoothly to avoid triggering a stretch reflex or muscle guarding.
  • Maintain an upright torso without leaning your entire body to the side.
  • Stop immediately if you feel any sharp pain, dizziness, or tingling down the arm.

Pro tips

  • To increase the stretch in the sternocleidomastoid, focus on 'reaching' your chin away from the anchored collarbone.
  • Exhale deeply as you rotate your head to encourage the muscles to relax into the new range of motion.

Make it harder

  • Apply very light overpressure by placing your non-anchored hand on the side of your head, pulling gently in the direction of the stretch.
  • Perform the stretch while actively depressing the scapula (shoulder blade) of the side being stretched.
