One-arm Contact Flow Training

The importance of one-arm Contact Flow training: you should develop the ability to attack and defend with one arm to the extent that you can deal with both of your opponent's arms with one arm. In motion he thinks he's in contact with both of yours when in reality you've got a spare. This training affords so many points of sensitive contact (elbow, hand, forearm, bicep, triceps, shoulder, etc.) that eventually when you mix it all together the opponent will feel like he's fighting an octopus with sledge hammers
