In an Ashtanga Yoga class the movement is continuous. As we move and flow through the practice we connect the postures to the ebb and flow of the breath. This makes for a moving meditation. Ashtanga Yoga is popular with those looking for a rigorous practice and who like a set sequence of postures. In a Primary Series class the postures will be the same each time. Expect continual movement and to sweat a lot, not because the room is heated, but the heat is created within the body due to the movement and the breath.
