Input: Consider Input: Question: What year was Bikram Choudhury's bodybuilder teacher born? Passage:Yet another of Krishnamacharya's pupils, K. Pattabhi Jois, came to the United States in 1975, starting a long-lasting craze in the country for Ashtanga Vinyasa Yoga. A vinyasa is a movement that connects yoga poses together; the result is a continuously flowing sequence that can be learnt and practised as a whole, making yoga into an energetic aerobic exercise. Ashtanga Yoga gave rise to various spinoff styles including Power Yoga in the 1990s, with one form created in 1995 by Beryl Bender Birch and others by Bryan Kest, a student of K. Pattabhi Jois, and Baron Baptiste, trained in the hot style of Bikram Yoga. Bikram Choudhury arrived in the United States in 1971, and by 1974 had created his own style of yoga, with the studios heated to . He was strongly charismatic, had been taught yoga by the bodybuilder B. C. Ghosh, Yogananda's youngest brother, and like Jois saw hatha yoga as a religion. The two men made yoga serious, hard work, with an intensity that demanded a lifestyle arranged around yoga; up to that point, it had been seen as a slow, gentle, feminine form of exercise, and classes had consisted mainly of women. Practice was so hot and sweaty, and required such mobility, that clothing was reduced to a new minimum: men often wore nothing but long shorts, while women wore footless leggings, sports bras, and small tank tops.
