2 1/2 [plus] hours + 100 degree room + 84 poses = determined, strong, and flexible individuals. i am in awe of the yogis that do this type of practice. i myself am a bikram addict and had the pleasure of working with boiler house yoga studio to help them document their 84 asana class progression. i think for now i personally will stick with bikram's 26!
