Professor Edson Oliveira demonstrates a cross collar choke technique. He begins by emphasizing the importance of proper head positioning to control the opponent. He details how to expose the opponent's collar and secure a deep grip with the fingers. Edson stresses the importance of hip placement to prevent the opponent from controlling the hand. He then shows how to finish the submission with the cross collar choke. He explains the hand positioning for the final grip and how to use body movement to increase the choke's effectiveness. Finally, he gives advice on the timing and application of the choke, emphasizing a gradual increase in pressure rather than a fast, forceful attempt.
