Neck Tension
People commonly state to me in my clinic that they hold tension in their neck from stress. I regularly state to clients that stretching the neck sideways, front and back is a great way to release muscles in the neck.
As a therapist I assist by passively helping clients stretch their necks by holding their shoulder down and instructing the client to stretch the other way slowly stretching more each time. Thus the stretch enables the muscle to be stretched without much pressure and help release the muscle.
