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. The movement practice of Vinyasa is said to begin with T Krishnamacharya who has had the largest influence on how yoga, in general, is practiced today.
Put all this together and Vinyasa, is a breath initiated practice, that connects every action of our life with the intention of moving towards what is sacred, or most important to us. Vinyasa Yoga connects one posture to the next using the breath. This can be thought of as linking or flowing into postures which is sometimes why it’s called “Flow Yoga”. The opposite of this would be an alignment based class where students engage with a posture, explore it for a period of time and then “break the posture” by coming out.
