Vinyasa flow classes are active and dynamic.
Vinyasa Yoga is characterized by a focus on vinyasa, or a dynamic connecting posture, that creates a flow between the more static traditional yoga postures. Vinyasa translates as linking and the system also implies the linking of the movement to the breath. Essentially the breath dictates the movement and the length of time held in the postures. Unlike some Hatha yoga styles, attention is also placed on the journey between the postures not just the postures themselves.
The vinyasa ‘flow’ is a variant of Surya namaskara, the Sun Salutation. The whole practice is defined by six specific series of postures, always done in the same order, combined with specific breathing patterns (Free breathing with the ujjayi sound).
A standard vinyasa consists (for example) of the flow from Caturanga, or plank, to Caturanga Dandasana, or low plank, to Ardhva Mukha Svanasana or upward-facing dog, to Adho Mukha Svanasana, or downward-facing dog.
The purpose of vinyasa is to create heat in the body, which leads to purification of the body through increased circulation and sweating. Ashtanga Vinyasa brings in the principles of Agni and inversion to purify the entire body. It also improves flexibility, as well as tendon and hard tissue strength, allowing the student to practice advanced postures with reduced risk of injury.
