Movement is simply moving weight in space. When sitting down, your head (which is the heaviest body part) often times is in front of the rest of your body—which causes the strain in your neck. Take notice of where your head is in relation to the rest of your body. Now, bend your head forward– which will allow the muscles to stop overworking. Feel the chain reaction through your whole body! When lifting your head back up, lift from your head not your neck. Notice if your breathing improves. Listen to your body–do this as often as you feel you need it.
