Professor Lucas Lepri teaches how to escape from the double under when the opponent is able to get a cross collar grip. The opponent has the double under on Lucas and starts to lift the hips off the ground. Lucas immediately makes his legs heavy by pointing his heels to the mat. The opponent first lifts one knee up and when he goes to stand up, Lucas immediately grips the collar pulling it down. The opponent now reaches under the collar grip to grip Lucas’ collar. He starts to move to the side in an attempt to pass. Lucas defends by pushing on the collar and uses his leg to help him push. The opponent posts out and Lucas takes advantage of this to slide his leg over the shoulder. He pulls the opponent back in and gets the triangle submission.
