Final answer:
The primary series in Ashtanga Yoga primarily focuses on forward bends, which is a form of flexion involving movements of the body in the sagittal plane.
Step-by-step explanation:
The primary series in Ashtanga Yoga, also referred to as Yoga Chikitsa, which means yoga therapy, primarily focuses on forward bends. These are physical movements in which the body is bending forward. This movement is a form of flexion which happens along the sagittal plane and involves anterior movements of the body. Forward bends are a significant part of the primary series, helping to stretch the back muscles and increase flexibility in the hamstrings and hips. Flexion and extension are essential movements of the vertebral column that are used frequently throughout the traditional Ashtanga yoga practice.
The primary series in yoga is primarily focused on forward bends. Forward bends involve flexion movements where the body or limbs move anteriorly or towards the front. These movements are commonly practiced in yoga to stretch the back and hamstrings and improve flexibility and balance.
