How to do the Cable Seated Neck Flexion (With Head Harness)
NeckCableBeginner
A strong neck is the foundation of head stability, injury resilience, and a complete physique that most lifters neglect entirely. The cable seated neck flexion with a head harness lets you apply consistent, scalable resistance through the full range of motion that bodyweight work simply cannot match.

Step-by-step
- Sit upright on a bench facing away from the cable stack, secure the head harness snugly around your skull, and attach it to a low cable pulley with light resistance.
- Begin with your head in a neutral or slightly extended position, keeping your spine tall and hands resting on your thighs for stability.
- Slowly flex your chin toward your chest in a controlled arc, fully shortening the neck flexors at the bottom without yanking or jerking.
- Reverse the movement under tension, returning your head to the start position over two to three seconds before initiating the next rep.
Common mistakes
- Using too much weight and turning the movement into a jerky pull — drop the load until you can control every inch of the range of motion smoothly.
- Rounding the upper back and letting the torso pitch forward — brace your core and sit tall so the neck does the work, not momentum from the spine.
- Shortening the range of motion by only nodding slightly — ensure you reach full chin-to-chest flexion and full controlled extension on every single rep.
Pro tip — Focus on the eccentric: resist the cable on the way back with a three-second count, because the neck flexors develop thickness and control fastest under slow, deliberate lengthening tension.
