Core strength is simply essential. Not only does a strong core help you maintain good posture and support your overall health and vitality, there is power in moving from your physical core center. When you feel strong on the inside, you can start to lean on and trust your inner wisdom—your body’s inherent intelligence. When you feel good in your body, your confidence will soar both on and off the mat, and stress and discomfort will start to melt away, igniting your personal power.
In this sequence, we’ll focus on working from the center of your body and developing your core strength. Amplify the benefits by linking your movements with your breath and using its pathway to step into more energy and ease. Hold all poses for 5–10 breaths the first time through. Once you feel confident with the flow, try moving through it again at a pace of 1 breath per movement. I suggest starting with 3 rounds each of Sun Salutation A and B as a warm-up. Note: Have a yoga block handy.
