I have been getting questions about the purpose of a plank pose in yoga. Also known as Kumbhakasana, Phalakasana, or Adho Mukha Dandasana, plank has a place in a vinyasa sun salutation flow, and it can also stand alone. Looking within the purpose of yoga to align, strengthen, and add mobility to the spine, a plank pose packs in a full session within breaths.
