'Mastysa (मत्स्य)' in sanskrit is Fish and 'asana (आसन)' is posture. This asana resembles the fish. Traditionally, it is done in padmasana. But variations are there for practitioners of different levels. In beginning it can be done with straight legs on the mat. It is a reclining back bend posture. So all the variations are designed focussing on this. Lets see how to perform the Fish Pose.
