I like to think of the ribs as a bell and you can ding or dong your ribcage. This can be a very challenging movement to do. We don’t want your ribcage bell donged back creating a roundness in your upper back nor do we want it dinged forward creating a rib thrust and an arch in your lower back. We want the rib in a neutral position between the bell ding and dong. This means that your chest will not slump forward, collapsed by your shoulders and pulling forward nor will it arch back in a military style pulled up and stiff. The upper body will be long and straight, yet free and flexible.
