Caio Terra is a four-time world champion in No-Gi Jiu-Jitsu, and he trains with some of the biggest MMA names around. Here, the Cesar Gracie student teaches how to get an opponent out of side-control, with the help of training partner Gilbert Melendez, who will soon be showing his stuff in the UFC. The MMA fighter counters by demonstrating how not to lose the position, and snag an armlock to boot.
