Professor Lucas Lepri demonstrates escape techniques from the north-south position. He explains that this position often occurs when an opponent blocks hip escapes from side control. He emphasizes avoiding common mistakes like pushing straight into the opponent or grabbing them, which wastes energy and exposes the arm. The key is to insert a hand inside, grip the opponent's gi, and rock to create space. He stresses the importance of keeping the knuckles pointed inward to prevent armbars. Lucas demonstrates rocking to the opposite side while bringing a leg across and lifting the hips to create space for an elbow escape. He highlights lifting the hips before placing the elbow to avoid getting stuck under the opponent's weight. He also shows how to regain guard after escaping, emphasizing the importance of getting the belt in front and maintaining control. He reinforces the escape by demonstrating the "pendulum" motion, using shoulder movement and hip lifts to create space and escape.
