Setup
- Stand or sit tall with your feet shoulder-width apart and shoulders retracted.
- Interlace your fingers and place your palms firmly against the back of your head.
- Tuck your chin slightly to ensure your cervical spine is in a neutral, elongated position.
How to do it
- Press the back of your head into your palms while using your hands to provide equal resistance so the head does not move.
- Exhale as you gradually increase the pressure, holding the contraction for 5 to 10 seconds.
- Inhale as you slowly release the tension before starting the next repetition.
- Maintain a steady, controlled effort throughout the hold without any jerking movements.
Form checklist
- Keep your chin tucked; do not allow your head to tilt upward.
- Keep your shoulders depressed and away from your ears.
- Ensure your torso remains upright and does not lean forward or backward.
- Apply pressure progressively rather than snapping into the contraction.
Pro tips
- Focus on 'lengthening' the back of your neck as you push to engage the deep cervical stabilizers.
- Visualize pushing your head straight back (retraction) rather than just tilting it back (extension) to maximize engagement.
Make it harder
- Increase the duration of each hold to 15-20 seconds.
- Perform the exercise while lying supine on a bench with your head unsupported, resisting both gravity and hand pressure.
