Two Approaches to Arm Lock Entries
There are two primary methods for securing an armlock from the north-south position: a quick explosive entry where the aggressor immediately commits their weight, and a slow methodical approach where sustained pressure and positioning prevent escape. The slow method is particularly effective because it maintains top control while restricting the opponent's options.
Deep Armpit Positioning and Elbow Control
The foundational positioning requires the aggressor to place their thumb toward their own head while achieving deep penetration into the opponent's armpit. This depth is critical because it prevents the opponent's elbow from escaping to the mat, which is the primary defensive mechanism, especially in no-gi grappling where friction is reduced.
Rolling and Body Weight Application
From the deep armpit position, the aggressor rolls their hand toward the mat while lowering their head and using body weight to pin the opponent's arm. The aggressor then maintains base on their toes and walks forward to create maximum friction and control, preventing the opponent from extracting their elbow.
Transition to Submission
Once the opponent's leg is positioned in front of their face, the aggressor is ready to finish by pinching their knees together and falling back into the armlock. This method maintains top position throughout the attack, so even if the opponent escapes, the aggressor retains positional control.
Calf Slice Transition
Using the identical entry and slow roll, the aggressor can transition to a calf slice submission by trapping the opponent's head between the calf and thigh. As the opponent's head naturally lifts off the mat during the slow entry, the aggressor simply slides their calf underneath and sits down with controlled pressure.
Calf Slice to Neck Choke
In competition settings, the aggressor can intensify the calf slice by positioning their calf on the opponent's neck rather than their jaw, which can result in unconsciousness through compression. In training, practitioners should avoid full weight distribution to the neck to maintain safety.
Paper Cutter Choke Setup
The paper cutter choke shares the identical initial setup and can be accessed by shifting sideways during the entry sequence. The aggressor maintains a steady frame by not collapsing the distance between shoulder and wrist, then applies angled pressure against the opponent's jawline rather than straight downward force.
Paper Cutter Pressure Application
The paper cutter choke requires minimal pressure when executed correctly, as the aggressor applies force at an angle toward the jawline rather than directly vertical. This angled frame uses the opponent's own structure against them, making it highly efficient despite appearing gentle.
