Professor Lucas Lepri demonstrates escapes from a side headlock. When caught in a side headlock, the initial defense involves grabbing the opponent's hand that is pulling the head down. Creating space is key, often by stepping a leg between the opponent's legs. Controlling the opponent's wrist limits their ability to maintain the headlock and strike. By using leverage and stepping, the trapped person can prevent their head from being forced down. Pushing the opponent away can create further distance and safety.
