The primary series of Ashtanga yoga consists of four sequences; Standing sequence, Seated sequence, Finishing sequence and the final three postures. Before the series begins, five rounds of Sun Salutation A and Sun Salutation B are practised. The series begins with 13 standing postures. Then comes vinyasas of 20 seated postures.

The primary series is a challenging and dynamic practice that focuses on building strength, flexibility, and stamina. It begins with sun salutations (Surya Namaskara A and B) to warm up the body and establish a steady breath. Following the sun salutations, there are a series of standing, seated, and finishing postures.

The first series is called the primary series or yoga chikitsa, and the second series is called the intermediate series. Following these are four advanced series. Each of these sequences has a set of ordered postures performed the same every time. They will begin with a series of poses called Sun Salutations, also known as Surya Namaskar.

The first series is also called the Ashtanga Primary Series. These classes could be conducted at a more moderate pace or provide a more balanced selection of poses than a traditional first series Ashtanga practice; but this depends upon the teacher. The entire series of poses here have to pass through the Power Yoga and Vinyasa classes.
