A two people drill with a chain: Start with one person standing against a wall and the other with a chain held tight (no sagging) between two hands works to wrap it around him and you have to escape using just your body, shoulders, neck and head. Progress to having a little slack in the chain so you can be more free and projectile in your movement and allow the use of the arms to the elbow point and slowly add more freedom to the chain until you can throw it around with control. Avoid getting to exited and throwing it wildly. Your partner will correct you very decisively. After this work in pairs or threes and have one or two working to wrap and take down or choke (work to control the other) and this teaches to control your fear through relaxation and movement and by using your body and shoulders/arms you learn to move efficiently and leave your forearms and fists/ hands to do other work. Think about the purpose of your work and you will get somewhere with it.
two tips: One is to have a chain around your shoulders as you work and this will teach you to move without rushing or jerking and to avoid getting too exited. The second is not to focus on the chain. It is the person that matters. A chain to the face will teach you to respect it of course but it is not the chain you are working with.
