In this video, Katie St. Clair talks about a key concept that I've recently started coaching all of our clients on who are learning how to diaphragmatically breathe more effectively to improve their mobility during their training, core strength, and bracing ability. To achieve the "wave pattern" that I talk about in my Diaphragmatic Breathing video in the Movement Foundations Course: if you inhale deeply into your ribcage to fill it and then maintain that fullness as you start your exhale from the bottom up, you will achieve much more diaphragm movement, a better stack, and therefore much faster progress.
