Bikram Yoga consists of a sequence of 26 postures (asanas) and two breathing exercises (pranayama), typically practiced in a room heated to around 40c (105°F ) with a humidity of 40%. This practice is designed to systematically work every part of the body, promoting flexibility, strength, and balance, while also aiding in detoxification through sweating. Each class lasts 90 minutes, and the sequence is always the same, allowing practitioners to focus on improving their form and depth in each posture over time. The class time can be reduced to 60 minutes for a shorter 'power-hour' class, with less posture repetition.
