The students of modern ashtanga yoga practice in two styles. Guided class and Mysuru (Mysore) style class.
The Mysuru style of practising yoga has become popular all over the world. This name became handy to the practitioners of yoga to tell others about their style of practice.
Both the guided and Mysuru style names have become convenient for the students to ask for what they want to do in the class to practice and for the teacher too who understands what the students like to do in his class.
