Here’s a quick morning stretching exercise. Actually you can do it anywhere, while waiting for a bus, standing in line for lunch or cooking over the stove.
Stand up straight and imagine a string attached to the top of your head. The string slowly tightens and lifts up your head and extends your neck. You are getting taller and taller as your neck and spine extend. Keep your eyes level and shoulders and jaw relaxed.
At the same time plant your feet firmly on the ground and apply pressure to your heels rooting them to the floor. Wriggle your toes and feel the ground.
You now have your head and neck extending like an ostrich and are anchored to the ground like an oak tree.
As you grow taller, every joint opens up from your knees, hips, spine, chest and neck.
Take 3 deep inhales and exhales while in this posture.
