Setup
- Position a flat bench facing away from a cable column with the pulley set to approximately head height while seated.
- Secure the head harness comfortably, ensuring the cable attachment point is centered on your forehead.
- Sit upright on the bench with your feet planted firmly for stability and grasp the edges of the bench for support.
- Adjust your distance from the machine so there is slight tension on the cable when your head is in a neutral position.
How to do it
- Start by allowing your head to tilt back slightly into a controlled stretch, keeping your torso completely stationary.
- Exhale as you flex your neck forward, tucking your chin toward your upper chest in a smooth, nodding motion.
- Hold the peak contraction at the bottom for one second, focusing on the tension in the front of your neck.
- Inhale as you slowly return your head to the starting position using a controlled 3-second eccentric tempo.
Form checklist
- Keep your shoulders depressed and pinned back; do not let them shrug toward your ears.
- Ensure the movement occurs only at the neck; avoid leaning your torso forward to move the weight.
- Maintain a slow and controlled tempo to avoid jarring the cervical spine.
- Keep your jaw relaxed and avoid clenching your teeth during the exertion phase.
Pro tips
- Focus on a 'rolling' motion of the chin toward the sternum rather than just pushing your head forward.
- Use a light weight to start; the neck muscles respond better to high-quality contractions and higher repetitions than heavy, ego-driven loads.
Make it harder
- Add a 2-3 second isometric hold at the point of maximum flexion (chin to chest).
- Perform '1.5 reps' by flexing fully, returning halfway, flexing again, and then returning to the start.
Frequently asked
- What muscles does the cable seated neck flexion with head harness work?
- The cable seated neck flexion with head harness primarily targets the trapezius, and also works the abs and obliques as secondary muscles.
- What equipment do you need for the cable seated neck flexion with head harness?
- The cable seated neck flexion with head harness uses cable.
- Is the cable seated neck flexion with head harness good for beginners?
