Ujjayi (ooo-ji-eee) Breath is a very ancient and traditional form of pranayama (or breath control) which you will very often hear cued in our classes. 

Our Founder Amy Leonard-King dives a little deeper on this breath sometimes affectionally known as "Darth Vader"  or "oceanic" breath which can help you to distribute prana through your body + garner control over the mind.
