Shiva Rea is such an inspirational yoga teacher. This flow is not too rigorous. It flows with beauty and feels lovely in the hips and heart. My recommendations: make sure you take the time to enjoy the spinal articulation as you roll down to the earth. Be aware of the length of the spine and head/tail connection. Also, when you come up in cobra, it is probably best to keep your elbows slightly bent. She straightens hers at the peak of cobra, be safe. Listen to your body. 🙂 Breathe and enjoy!
