Weighted Lying Neck Flexion With Head Harness
- Intermediate
- Isolation
- Rep-based
- Neck
- Shoulders
- Waist
This isolation exercise targets the anterior neck flexors, specifically the sternocleidomastoid and scalenes, to build thickness and improve cervical stability. Using a harness allows for safe progressive overload while maintaining a consistent line of pull throughout the range of motion.

Setup
- Secure the head harness comfortably around your head and attach the desired weight plate to the chain.
- Lie supine (on your back) on the bench with your head and neck hanging completely off the edge.
- Position your body so your shoulders are flush with the edge of the bench and plant your feet firmly on the floor for stability.
How to do it
- Inhale as you slowly lower your head toward the floor in a controlled manner until you feel a deep stretch in the front of your neck.
- Exhale and flex your neck to bring your chin toward your chest, moving in a smooth arc-like motion.
- Pause for a split second at the peak of the contraction before slowly returning to the starting position.
- Maintain a controlled 2-1-2-0 tempo (2 seconds down, 1 second pause, 2 seconds up).
Form checklist
- Keep your upper back and shoulders pinned to the bench; do not use your torso to help lift the weight.
- Ensure the harness is centered on your head to avoid uneven strain on the cervical spine.
- Avoid any rapid or jerking movements; the neck is a sensitive area that requires strict control.
- Keep your jaw relaxed and avoid clenching your teeth during the exertion phase.
Pro tips
- Focus on the 'chin-to-chest' cue to maximize the recruitment of the sternocleidomastoid muscles.
- Use a light touch with your hands on the bench or your sides to ensure all force is generated by the neck flexors.
- Start with a very light weight to establish a mind-muscle connection before attempting to increase resistance.
Make it harder
- Add a 3-second isometric hold at the peak of the flexion to increase time under tension.
- Incorporate '1.5 reps' by performing a full repetition followed by a half-repetition from the bottom to the midpoint.
Frequently asked
- What muscles does the weighted lying neck flexion with head harness work?
- The weighted lying neck flexion with head harness primarily targets the abs and obliques, and also works the deltoids, erector spinae, and trapezius as secondary muscles.
- What equipment do you need for the weighted lying neck flexion with head harness?
- The weighted lying neck flexion with head harness uses weight plate.
- Is the weighted lying neck flexion with head harness good for beginners?
- The weighted lying neck flexion with head harness is rated intermediate. Build a base with simpler variations first, then progress to it with light load and strict form.
