Pay close attention here as this technique is vitally important to improving your breathing. Rock and Roll is the basis for relearning how to breathe in an anatomically congruous way. We are training our diaphragm, breathing muscles, and our brain to breathe more efficiently. This exercise is so important that it appears in nearly every one of the 14 workouts. Make sure your shoulders aren’t coming up when you inhale. Focus on expanding your belly, ribs, and back on the inhale while rocking your pelvis forwards. On the exhale, roll your pelvis back and think of squeezing your belly all the way around and bringing your navel to your spine.
