As a repertoire of postures were promoted to exercise the body-mind over the centuries, to the present day when yoga is sought as a primarily physical exercise form, modern usage has come to include variations from lying on the back and standing on the head, to a variety of other positions. However, in the Yoga sutras, Patanjali mentions the execution of sitting with a steadfast mind for extended periods as the third of the eight limbs of Classical or Raja yoga, but does not reference standing postures or kriyās. Yoga practitioners (even those who are adepts at various complex postures) who seek the "simple" practice of chair-less sitting generally find it impossible or surprisingly grueling to sit still for the traditional minimum of one hour (as still practiced in eastern Vipassana), some of them then dedicating their practice to sitting asana and the sensations and mind-states that arise and evaporate in extended sits.

Asana later became a term for various postures useful for restoring and maintaining a practitioner's well-being and improving the body's flexibility and vitality, with the goal of cultivating the ability to remain in seated meditation for extended periods. Asanas are widely known as "Yoga postures" or "Yoga positions".
Yoga in the West is commonly practised as physical exercise or alternative medicine, rather than as the spiritual self-mastery meditation skill it is more associated with in the East.
