Whew… Don’t be intimated. Upward Facing Dog is part of the Vinyasa flow and Yin to the Yang of Downward Facing Dog (Adho mukha svanasana). Upward facing down is a backward-bending arm pose with the goal of elongation through the entire spine. Upward Facing Dog is really an extension pose, that is part of the process for deeper backbends. Your arms, back, legs, and feet are extending while in the pose. While transition into Upward Facing Dog you will inhale to deepen the extension in your thoracic spine. The exhale will happen when you transition to the “Yang” of Upward Facing Dog.
Upward Facing Dog is a key part of your Sun Salutation and also essential in transitioning to Downward Facing Dog. Remember, what goes up must come down!
