Bikram Yoga is a system of hot yoga, a type of yoga as exercise, devised by Bikram Choudhury and based on the teachings of B. C. Ghosh, that became popular in the early 1970s. Classes consist of a fixed sequence of 26 postures, practised in a room heated to with a humidity of 40%, intended to replicate the climate of India. The room is fitted with carpets and the walls are covered in mirrors. The instructor may adjust the students' yoga postures. Choudhury's teaching style was abrasive. Bikram Yoga spread rapidly across America and the Western world, reaching a peak of some 1,650 studios in at least 40 countries in 2006. Choudhury attempted to copyright the Bikram Yoga sequence from 2011, but was ultimately unsuccessful. In 2016, facing lawsuits and accusations of sexual assault, Choudhury fled to India, leaving Bikram Yoga, Inc. to be run by others. Origins Bikram Choudhury was born in Calcutta in 1944. He began studying yoga in 1969. He arrived in America in 1971, and soon began to teach yoga in health resorts in California. In 1974, two pupils, Shirley MacLaine and Anne Marie Bennstrom, helped him to open his own school at 9441 Wilshire Boulevard in Los Angeles. He attracted celebrity pupils including the Hollywood dancer Marge Champion and the actors Keir Dullea, Martin Sheen, Susan Sarandon, and Raquel Welch. Yoga classes were initially free, with a donation box. Maclaine told Choudhury he could not run an American yoga school like one in India, and he began to charge $5 for classes; attendance started to grow at once. Choudhury later devised the 26-posture sequence of Bikram Yoga, based on the teachings of B. C. Ghosh.
