Tense the front of your neck and than the left side and the back and than the right side creating a circle of tension and relax in the opposite directions. Do this on the inhale and than on the exhale. Now bend your neck in some way and repeat the drill. Do this several times to get to know how one tense spot affects the tension in others and than have a partner push your head using his fingertips first and you breathe and let the lightest movement move the head as you mind to let it move the least. For example if you have pressure on the side of the temple avoid moving from the neck and let the head move in more than one direction at once so the chin moves toward the tension and the forehead forward or backwards and the given result is much less discomforting and a lot swifter due to your awareness rather than speed. Repeat the drill as you tense one part of the neck and see how you can work around this tension and than as your partner strangles you in some hold and hits you with the other arm.

Nothing works better than brething so focus on it.
