GUYS and girls remember it is very important to follow proper technique and breathing procedure. Knowledge of right postures and inhaling and exhaling is extremely critical and important or you can damage your body.
Kindly pay attention to moves and teacher's instructions . infact I suggest if you are new to this first just watch it a few times and carefully listen to instructions and rhythm of movements and breathing pattern and understand. Then only physically practice.
