The Planka is not a classical asana. However, most yoga asanas require a sufficiently high level of fitness and a good awareness of the cortex, i.e. the muscle group that forms the central muscular corset that protects the vital organs. Because the plank position is good for endurance training and strengthening the cortex, it was included in the Surya Namaskar complex at the beginning of the 20th century and is often used as an element of the linking sequence of asanas, vinyasa.
