Ashtanga is power yoga at its best! An Ashtanga class begins with five repetitions of Surya Namaskara A and five repetitions of Surya Namaskara B, followed by a standing sequence, the series, and the closing sequence. So you are always practicing the same set of asana, gradually but steadily building strength and gauging your progress. This type of class is perfect for those who want to challenge their bodies and sit with their breath. All levels welcome!.
