Professor Lucas Lepri shows how to get an arm triangle choke, after attempting to counter a single leg. The opponent shoots for the single leg and Lucas immediately slides his near side arm under the neck to the opposite side armpit and grips his hands together. Lucas attempts to kick his foot to the ground and sprawl over the opponent to counter the single leg, but is not able to and the opponent takes Lucas down. Lucas falls with the opponent and maintains his grips. He uses his top leg to trap the opponent’s top arm and slides his palm to his bicep to get the arm triangle submission.
