Ashtanga Vinyasa Yoga — the traditional sequence, at a pace that meets your body.

Ashtanga Vinyasa Yoga is a structured and dynamic style of yoga that links breath with a fixed sequence of postures.
It all began in Mysore. Krishnamacharya, often called the father of modern yoga, is said to have healed the Maharaja through yoga, and in gratitude the king gave him a yoga shala at the palace. His schoolroom was the old gymnasium, ropes still hanging from the ceiling. Among his students were B.K.S. Iyengar and Pattabhi Jois. 
Tradition tells that the sequences come from the Yoga Kurunta, an ancient text Krishnamacharya is said to have studied, of which no copy has survived. What we know for sure is that Pattabhi Jois shaped what he learned into the practice we know today: movement, breath and gaze, in a fixed order, the same every time. In the 1960s the first Westerners found their way to Mysore, and slowly Ashtanga travelled out into the world.
The practice is built around set series of postures (asanas), performed in the same order each time. Traditionally there are six series, starting with the Primary Series — Yoga Chikitsa, “therapy” — which is designed to detoxify and align the body. Each movement is synchronized with an inhalation or exhalation, in a flowing style called vinyasa.
