Postural Practice Pointer 9 – Back bends are Pūrvatāna Āsana or Front Stretches
Prone Backbends as front stretches are wall to wall Āsana
in terms of Bhāvana, rather than floor to ceiling.
Thus in Sālamba Bhujaṅgāsana the focus is on
the sternum stretching forwards and
the big toes stretching backwards.
