Hi Rashmi,
Bikram yoga is also known as Hot yoga. It is performed in a room temperature of 105 degree F and humidity level 50% and it involves 26 postures and 2 breathing exercises in 90 minutes. Bikram yoga is considered good for fat loss and the rationale behind it is increase in metabolic rate which leads to burn fat thereby weight loss. I am not clear with the effectiveness of Bikram yoga, and I feel weight loss seen might be because of dehydration and not the fat loss. Thus, their is danger of dehydration and other related disorders.
