Anaconda choke video
Info about "Anaconda choke video"
An anaconda choke is an arm triangle from the front headlock position. The performer threads his or her arm under the opponent’s neck and through the armpit, and grasps the biceps of the opposing arm. The performer then attempts to pin the opponent onto the trapped shoulder so as to better interrupt the flow of blood, all the while applying pressure with the grasped biceps.
The performer may accomplish this by rolling the opponent over the untrapped shoulder, (known as a gator roll) and use the momentum to turn the opponent onto his or her trapped shoulder. Antônio Rodrigo Nogueira was the first one to use it in MMA, although he and his twin brother learned this submission from Milton “Miltinho” Vieira.
