My Favorite Arm Isolation Method

This has become my favorite way to isolate the limbs of a strong defensive opponent. Using the Overload Principle, the shin of my north leg drives the opponent’s arm to the ground in a direction where they have very little resistance/strength. With the inside arm anchored to the mat, I can begin attacking their outside arm with two hands to either a) catch the crucifix if they stay flat, or b) catch the D’Arce if they turn in, a perfect illustration of the Fork Principle. 🙏🏼
