Setup
- Secure the head harness comfortably around your head and attach a light weight plate to the chain.
- Lie sideways on a flat bench so that your shoulder is aligned with the edge, allowing your head and neck to hang off the side.
- Support your body by gripping the side of the bench with your bottom arm and stacking your legs for stability.
- Start with your head in a neutral position, parallel to the floor, with the weight hanging straight down.
How to do it
- Inhale and slowly lower your ear toward the shoulder closest to the floor in a controlled manner.
- Exhale as you contract the side of your neck to lift your head upward toward the ceiling, moving past the neutral starting point.
- Hold the peak contraction at the top for one second, ensuring you don't rotate your head.
- Lower the weight back to the starting position using a slow 3-second eccentric tempo.
Form checklist
- Keep your torso and shoulders completely still; only the neck should move.
- Maintain a slight chin tuck throughout the movement to protect the cervical spine.
- Ensure the harness is centered so the weight pulls straight down without twisting your neck.
- Move through a pain-free range of motion; do not force the stretch at the bottom.
Pro tips
- Focus on the mind-muscle connection by imagining your ear moving toward your shoulder to maximize lateral flexor recruitment.
- Perform the movement in front of a mirror if possible to ensure your head stays in a strictly lateral plane without tilting forward or backward.
Make it harder
- Add a 3-second isometric hold at the top of each repetition to increase time under tension.
- Slow the eccentric (lowering) phase to 5 seconds to challenge the stability of the neck muscles.
