In a seated or standing position, elongate your spine for a tall, straight back. Moving your jaws up and down like you are chewing and keeping your lips together, inhale deeply through your nose then slowly exhale while humming. When you finish the exhale, open your mouth as wide as possible with the tip of your tongue gently pressed against the back of your bottom teeth. Holding this position, inhale then exhale with an audible “ahhh” sound. The entire move should take 90 seconds. That’s one rep. Complete two.
