Doing yoga in the sauna sounds pretty silly, but you'll be amazed at how much calories it burns and how rejuvenating it is!
I started Bikram Yoga recently. It's a series of 26 yoga poses done in a heated room (40C/104F). The first half hour, we are not allowed to drink water; we're allowed to take sips of water there after. Then, we move on to the standing series and the floor series- where we spend half of our time lying down on the floor, relaxing.
Bikram Yoga, with it's slow poses and relaxation, surprisingly makes me sweat like I've never sweat before. Every article of my clothing are soaked in sweat and my whole body is drenched after each sessions. It burns anywhere between 350- 1000 calories each 90 minute session.
More surprisingly, it's really rejuvenating. I couldn't sleep last weekend so I stayed up all night and went to the 8am yoga class on Sunday. Instead of not having the energy to follow every move, I had more energy than ever before. I guess my body realizes I really need yoga.
My goal for this year is to do yoga at least once a week! You should try it too! :)
