Which yoga style consists of a sequence of 26 postures performed twice in a heated room?

Bikram Yoga is characterized by its specific format of 26 postures that are performed in a consistent sequence. The practice takes place in a room heated to around 105°F (40°C) with high humidity, which is intended to promote flexibility, detoxification, and increased heart rate. This style emphasizes the same series of postures in every class, allowing practitioners to deepen their understanding and mastery of the poses over time. The heat facilitates the stretching and can help prevent injury, making it a distinctive feature of Bikram Yoga compared to other styles that may not have a set structure or heated environment.

Power Yoga, Vinyasa Yoga, and Ashtanga Yoga incorporate moving through postures in a flowing manner but do not specifically adhere to the unique sequence and temperature regulation that defines Bikram Yoga. This clear differentiation underscores why Bikram Yoga is the correct choice for this question.
