Ashtanga yoga is a dynamic and exciting form of Hatha yoga. It is an ancient Indian yoga system that, through a set of sequences and postures, allows the body to progressively open and strengthen. The sequence of postures is combined with a specific breathing technique and internal "locks", which are the key to a deeper practice and bring energy to the core of the body, so tightness in the outer muscles can release. Listening to the mantra-like sound of their breath, the practitioner flows through the sequence in a form of moving mediation that is both energising and deeply calming.
