Neck Crank Defence
SubFamilyネッククランクディフェンス(Nekku Kuranku Difensu)
TransliterationTranslation: neck crank defence
Overview
The Neck Crank Defence subfamily covers defences against submissions that apply rotational or lateral bending force to the cervical spine, including can openers, neck crank variations, and face locks. [1] Neck crank defence prioritises aligning the spine and preventing the opponent from creating the angle needed to apply twisting or bending force to the neck. [1],[2] The defender works to tuck the chin, align the spine with the torso, and strip the opponent's grip before the cranking force can build to dangerous levels. [2],[3]
History & Origin
Neck crank defences have been taught in grappling arts since the earliest development of cervical spine submissions, with particular emphasis in catch wrestling where neck cranks are common finishing techniques. [1] Modern BJJ and MMA training includes specific neck crank defence as part of the submission defence curriculum. [2],[3]

Biomechanical Mechanism
Primary Action — Using foot positioning to control range and angles — maintaining optimal distance relative to the opponent
Joints Involved — Ankles (pivot and directional changes), knees (level maintenance), hips (balance and weight distribution)
Force Vector — Multi-directional — lateral steps, pivots, and retreats adjust distance and angle simultaneously
Distance Principle — Managing the distance between fighters is the most fundamental defensive skill — controlling range dictates which techniques are available
Position & Entry
From clinch or ground — When the opponent secures a controlling grip, use two-on-one, stripping, or peeling motions to break their hold
As preemptive defence — Break the opponent's grip before they can execute their intended technique

✓Neck crank defence addresses can openers, neck-crank guillotines, and other attacks that force the cervical spine into flexion, extension, or lateral bending (Danaher, Front Headlock System, 2019)
✓Tuck the chin firmly and shrug the shoulders — this closes the space around the neck and limits the range of cranking
✓Turn your body toward the cranking force to reduce the rotational load on the cervical spine
✓Frame on the opponent's hips or chest to create distance — cranks require close proximity to generate force
✓The can opener (pulling the head from closed guard) is the most common neck crank — open the guard and posture to relieve pressure
✓Against neck-crank guillotines, focus on posture recovery first: head up, back straight, circle to the choking side
✓Strengthen the neck with isometric holds, bridges, and resistance exercises — neck strength buys critical seconds for escape
✓In competition, neck cranks may be illegal at certain levels — know the rules but train the defence regardless
Common Mistakes
!Fighting the crank by pulling the head in the opposite direction — this doubles the force on the cervical spine
!Keeping the guard closed during a can opener — open the guard to relieve the cranking pressure
!Not tucking the chin — an exposed neck allows full range of cranking motion
!Relying on neck strength alone — technique (turning the body, framing) must accompany strength
!Ignoring the position that allowed the crank — if you escape the crank but remain in the same position, it will be re-applied
!Not training neck crank defence because 'they're illegal in my division' — accidents happen; know the defence
!Staying calm but not actively working to escape — calmness is the baseline; you must combine it with technical defence

Frequently Asked Questions
How do I prevent someone from breaking my posture when they have a neck crank?
Vladimir Trubin teaches that you should hug their far hip and hit inward—the harder they try to pull down, the harder you drive your hip in toward them to maintain your posture and prevent them from breaking you down.
What's the key to escaping a neck crank once it's locked in?
Trubin emphasizes pinching the attacking arm down to your body, then stepping out to create distance and disengage from the position.
Where should I keep my neck to defend against a neck crank?
Keep your back and neck straight and drop your posture rather than letting your head get pulled forward—this protects you from the worst of the crank pressure.
Why should I keep my opponent's arm glued to my body during neck crank defense?
By gluing their arm to your body, any movement you make will move their arm as well, giving you more control and preventing them from adjusting their grip as you step out to escape.
