John Scott explains Ashtanga Vinyasa Yoga. This is a system of yoga popularized by K. Pattabhi Jois and is often promoted as a modern-day form of classical Indian yoga. The term vinyasa refers to the alignment of movement and breath, a method which turns static yoga postures into a dynamic flow. The length of one inhale or one exhale dictates the length of time spent transitioning between postures. Poses are then held for a predefined number of breaths. In effect, attention is placed on the breath and the journey between the postures rather than solely on achieving perfect body alignment in a pose, as is emphasized in Hatha yoga.
