STOP AND NOTICE how you are using your laptop or mobile as you read this. We have habits which are out of our awareness.
If you are sitting are you sitting in a slump ? Are you sitting on your sitting bones? Are your shoulders hunched forward? Are your feet wrapped around the chair ?
If you are standing is your weight equal through both of your feet? Are your knees locked back? Notice if your shoulders are hunched and your neck is poked forward.
Notice how your head is balancing on top of your spine imagine it’s like a ping pong ball just floating.
Look straight at a mirror then put a finger in the hollow at the back of each ear and slowly nod your head. Notice where the movement is happening, this is your head neck joint. If this joint is tight it will affect your overall use, the way you move. Imagine space in the joint and fill it with oil. Doing this regularly will help you get more awareness of the atlanto occipital joint (head neck joint).
