Vinyasa is a style of yoga characterized by sequencing postures together so that you move from one to another, seamlessly, using the breath. Commonly referred to as “flow” yoga if done well you move into a flow state – a zen like movement of breath and body.
Vinyasa classes offer a variety of postures and no two classes are alike. The opposite would be “fixed forms” such as Ashtanga which has the same sequence every time.
The variable nature of Vinyasa Yoga helps to develop a more balanced body as well as prevent repetitive motion injuries that can happen if you are always doing the same thing every day.
