Bhujangasana (Cobra Pose)

Cobra is most often done as part of a Sun Salutation. It's the alternative to Upward Facing Dog (Urdhva Mukha Shvanasana) in the Vinyasa sequence for beginners. Cobra Pose is a great way to counteract the effects of slouching and slumping your shoulders. It stretches the spine and can help strengthen the muscles that support your head and neck.

Place your palms flat on the ground directly under your shoulders. Bend your elbows straight back and hug them into your sides.
Pause for a moment looking straight down at your mat with your neck in a neutral position. Anchor your pubic bone to the floor.
Inhale to lift your chest off the floor. Roll your shoulders back and keep your low ribs on the floor. Make sure your elbows continue hugging your sides. Don't let them wing out to either side.
Keep your neck neutral. Your gaze should stay on the floor.
Exhale to release back to the floor (or push back to Downward Facing Dog, Adho Mukha Svanasana, if you are doing a Sun Salutation).
