Why 90 Minutes
The Bikram yoga series was created by Bikram Choudhury as a 90 minute yoga routine, consisting of twenty six Hatha yoga postures each done twice and two Pranayama breathing exercises. Conducted in a heated room to 40 Deg C and 40% humidity. An authentic Bikram Yoga class is and has always been this and nothing else.
The series is a therapeutic style of Yoga. In other words it is a series that has been devised to heal the body. Each posture has been chosen for its very specific benefits and its relationship with other postures to work deeply into every single part of your being. In fact, every single cell.
The nature of the stretch and then subsequent compress that occurs as you do each posture twice is what is causing the healing benefits. The first set prepares the body while the second set ensures maximum delivery of medical benefits. Your body will always go deeper in the second set and this is where the yoga is working its magic. Stretch, compress, stretch, compress, stretch, compress for 90 minutes.
The wisdom of the ancients knew that you could use your body to heal your body. Bikram is drawing upon his 65 years experience as a yoga healer to present a 90 minute class.
