Rib expansion

The ribs lifting and swinging outward on the in-breath. Each rib pivots at its joints with the spine, raising the breastbone forward and widening the ribcage sideways, so the chest grows in both directions rather than just puffing up. Good looks like: even widening on both sides low in the ribcage, the breastbone rising gently, and no bracing of the neck to help. Stiffness here forces the neck and shoulders to do the breathing instead.
