Begin with the Right Sitting Posture

You can sit in any yogic posture like Padmasan, Siddhasan or simple Sukhasan. Sukhasan means crossing your legs normally comfortably and sitting down. You can use a carpet or a mat if you so wish.

If due to any medical problem you are unable to sit on the ground you can sit on a chair and also do Pranayam.

Kindly note that your spine has to be always erect while doing Pranayam in whichever position you are sitting unless you are suffering from any spinal problem.
