I can not say enough wonderful things about SunstoneFit and its abilities to teach yoga with a foundational perspective. A pose like down dog is not a resting station or just an easy place to start a sequence. It's quite complex and rather hard work, especially if you're activating your body. Their instructors will help you to push, pull, and feel it in all the right places, while maintaining ease and breath. Sunstone taught me down dog, the real one. The tail bone lifting, shoulder and hamstring opening, arm and core activating, neck releasing, spine extending, capital double D, Down Dog.
