Seated Chin Tuck

  • Beginner
  • Isolation
  • Rep-based
  • Back
  • Neck

The seated chin tuck is a foundational corrective exercise that strengthens the deep cervical flexors to improve posture and alleviate neck strain. It specifically targets the muscles responsible for stabilizing the neck and counteracting 'forward head' posture.

Setup

  1. Sit upright on the edge of a flat bench with your feet flat on the floor and your spine in a neutral position.
  2. Rest your hands comfortably on your lap and roll your shoulders back and down.
  3. Look straight ahead at eye level, ensuring your head is in a neutral starting position.

How to do it

  1. Inhale deeply, then exhale as you slowly draw your chin straight back toward your neck as if making a 'double chin'.
  2. Maintain a level gaze, ensuring your head does not tilt upward or downward during the movement.
  3. Hold the retracted position for 2-3 seconds while maintaining tension in the front of the neck.
  4. Inhale as you slowly return your head to the neutral starting position.

Form checklist

  • Keep your eyes fixed on a point at eye level to avoid tilting the head.
  • Ensure your shoulders remain still and do not shrug toward your ears.
  • Focus on horizontal movement rather than vertical nodding.
  • Keep your jaw relaxed and teeth slightly apart to avoid clenching.

Pro tips

  • Imagine a string pulling the crown of your head toward the ceiling to maintain spinal length throughout the tuck.
  • Focus on feeling a gentle stretch at the base of your skull and engagement in the deep muscles at the front of your throat.

Make it harder

  • Perform the movement while lying supine (on your back) on the bench to work against gravity.
  • Apply light manual resistance by placing two fingers on your chin and pushing gently as you tuck back.
