I did hot Bikram yoga this past weekend for the first time. My friend that invited me told me how it would last 90 minutes and that I didn't need to worry about doing all the poses but instead just try to stay in the room the whole time. The temperature in the room was 92 or 93 degrees, the instructor would walk around and open the windows and doors of the room to cool it off about two or three times over the length of the course. Yes, it was hot, and yes I was surprised that the class would last for so long but was it 'hard', no. Yes, I was sweaty but I felt as though the sweat dripping from all parts of my body was merely related to the fact that it was hot temperature wise, and it wasn't that I was working so hard at this 'workout' to cause my body to perspire.
So I did all the poses except those that I felt might hurt my knees, which are not so great due to all the running I've been doing. I have an Ironman coming up so I don't need to do anything to screw up my body or potentially cause me to be injured. They do all the poses twice and it seems like in between each of the poses you just lay on the ground and rest. Lots of resting. Apparently, they do the same set of poses every time in the same order so you always know what to expect when you go. I can certainly understand how people would enjoy going continually and watching their progress and they become more flexible and balanced. I would go again, but I don't think I will because it just wasn't hard enough. I kind of thought it wouldn't be hard enough for me but I didn't want to knock it until I tried it. Granted, the fact that I am training for an Ironman probably lent to the fact that it wasn't hard and if I had attempted to do this class pre-Ironman training I likely would have found it challenging so I can understand how it is for most people. And I will certainly fall back into the category of 'most people' after I finish this Ironman and get back on a normal workout schedule rather than a part time job type workout dedication (15-20 hours per week).
So, in a nutshell, it was fun and it was a new experience and I am glad I got to see what it was all about. But for me, I want to earn my sweat through effort.
