Hanging out in the heat isn't just for beachgoers or furnace installers. It's also for Bikram yoga practitioners, who boost their flexibility and elongate their muscles thanks to heated yoga classes. During sessions at Bikram Yoga Astoria Queens, members move through 26 asanas, or postures, as the temperature climbs to 105 degrees. They also incorporate breathing exercises into their poses, which help to alleviate stress. In addition to increased flexibility, the practice detoxifies the body, strengthens the midsection, and builds discipline—benefits each of the instructors continue to experience and share with their students.
