Foundation and Stance Requirements

The inside-to-outside block is performed from chunko jasa (front stance), requiring the same fundamental hip alignment and squaring principles as the low block. Practitioners unfamiliar with proper front stance mechanics should review foundational stance instruction before proceeding with this technique.

Block Mechanics and Motion

The block originates from across the body in a scraping motion, as if removing an obstruction from the tricep. The blocking arm travels in front of the face at approximately 30 degrees, creating a triangular gap between the body and arm that allows clear sight lines over the block.

Proper Arm Positioning and Alignment

The fists remain positioned with the block directly in front of the face—neither too high, too low, too narrow, nor too long. The wrist must remain in line with the forearm, and contact should be made with the outer edge of the arm using the hard striking surface, with the wrist pointing upward throughout execution.

Common Technical Errors

Three primary mistakes include: incorrect block angle that extends outside the body's protective square, using the inside arm rather than crossing on the outside with proper scraping motion, and bending the wrist forward, which compromises structural alignment and limits follow-up striking options.

Wrist Grab Application Drill

Partners execute the block by stepping back into front stance when their wrist is grabbed, effectively turning the opponent away and creating angles for striking. Practitioners should perform four to five repetitions on each side, gradually increasing speed and adding chaotic movement patterns.

Stance Integration and Power Development

The inside-to-outside block requires a strong stance foundation to execute correctly. Partners can practice simultaneous blocks in horse-riding stance, using either strength-based or flowing drill variations to develop proper positioning and discover the block's optimal power generation angle.

Close-Quarter Scenario and Lapel Defense

When a partner grabs the lapel, the defender strikes down on the opponent's arm while covering the head, executes the crossing motion, and uses the pulling hand to secure the opponent's wrist before stepping forward into front stance to deliver the block. This progression builds complete application from clinch range through proper block execution.
