Bikram yoga is tough but good if you can stick it. One word of warning - I didn't know it was not recommended for people with dry skin. I did it for a month and part of the problem was that there was a queue for the showers. After a week I got fed up and just towel dried myself and went home and showered at home. Big mistake. You sweat buckets in Bikram yoga, during and afterwards, and all the salt took its toll. I came out in a bad rash and it took a good while to get my skin back to normal.
