//01—About this position

What it is

Compact defensive posture where you pull your arms tight to protect your neck and face when escape is not immediately possible. Your elbows stay close to your body while you maintain breathing room and wait for chances to recover guard. This position reduces damage and preserves energy while you look for escape opportunities.
