When in Yoga you hear talking about Yin and Yang styles and being Yang significative of a type of Yoga which warms the body up, Vinyasa is able to heat up your system very well producing a more aerobic type of training.
Vinyasa is the term commonly used to indicate a specific sequence of poses which kind of “links” different other sequences, sometimes it is placed between single poses (asanas). The sequence is usually a jump back from standing, plank, Chaturanga Dandasana (low plank), Urdhva Mukha Svanasana (Upward Dod), Adho Mukha Svanasana (Downward Dog). So when you hear “TAKE A VINYASA”, that’s what you have to do…
Then every Yoga Instructor will modulate this with its likes and dislikes, you might have light versions, tough ones, but the idea of them all is to produce heat in the body, make the body stronger so to achieve stability and balance.
It keeps the attention on the whole flow rather than on single poses, which might be kept for a single breath. In this way transitions become as important and crucial as every single pose. It is almost like a dance that is performed in accordance with the breath which becomes one of your “companions” during the time of the practice as it is “keeping the attention on the bandhas”.
Personally, my method of sharing this style with others is to use what I call “Yoga Malas”, that would be some short sequences of poses which you can perform more than once repeatedly, so you can learn better the poses and gain more strength. Every Yoga Mala is linked with Vinyasa.
