Hot yoga refers to yoga exercises performed under hot and humid conditions. Often associated with the style devised by Bikram Choudhury, hot yoga is now used to describe any number of yoga styles that use heat to increase an individual's flexibility in the poses. In colder climates, hot yoga often seeks to replicate the heat and humidity of India where yoga originated. Some forms of hot yoga include:
Bikram Yoga was brought to the U.S. in the early 70s and became the most widely known form of hot yoga.
TriBalance Yoga another form of hot yoga, performed in slightly warmer but less humid conditions than Bikram Yoga.
Moksha Yoga founded in 2004 by Jessica Robertson, Ted Grand, and Natalia Brajak in Canada. This style of yoga is performed in a room heated to approximately 100 degrees and follows a series of 40 asanas, though teachers are free and encouraged to bring their own unique knowledge and experience to their class.
