While 360° lateral costal breathing might seem like a new concept, it’s deeply rooted in ancient practices. The idea of expanding the ribcage laterally during inhalation is intrinsic to many traditional breathwork modalities, such as pranayama in yoga. The lateral costal focus—where the ribs move outward like an accordion—was a subtle but crucial aspect of these teachings, designed to optimize diaphragm movement, create a sense of calm, and improve energy flow.
