Bikram Yoga is also known as ‘Hot Yoga’ because it is practiced in a hot room between the temperatures of 36-37 degrees Celsius/ 95-100 degrees Fahrenheit. The heat produced is said to encourage purification of toxins through perspiration and loosens up the muscles. Hot Yoga comprises a set of 26 poses done repeatedly. The various styles of yoga consequently present various challenges. Whichever form of Yoga you opt for, it depends on how much you wish to confront yourself.
