Professor Lucas Lepri teaches how get a toe hold submission using the one leg X. Lucas starts with the de la riva and uses it to unbalance the opponent. He pushes and pulls the opponent so he can lift him up with his legs. Lucas uses the grip on the pants to slide the leg over and transitions to the one leg x. He uses the legs to push the opponent back to get a reaction. The opponent starts to turn the knee in, Lucas maintains the grip on the pants and squeezes his knees together. Lucas now pushes the opponent in the direction of the knee to raise the same side foot off the mat. Lucas now reaches for the foot and locks in the toe hold submission. If the opponent rolls to defend, then Lucas just rolls and follows the opponent.
