yoga

Ok so I have decided that in my down time at work I want to try to pick up some exercise. I know I'm going to sound like a bimbo but I'm trying to keep the sweat to a minimum in this particular case just because I will be at work....basically save the cardio and such for home.

I had asked for a good website yesterday for crunches and ab work outs and have found some awesome exercises to do. But I would like to pair it with some yoga stretches as well. I did this in college and it was awesome and I think it would be perfect for when I am trying to do it. Hopefully.

But my question is do you do better creating your own yoga routine (checking out different poses, writing them down then doing them) or do you do better being guided (classes, dvds, etc)? I can't decide if it's worth trying youtube videos or not since there are some big chances of being interupted. I was thinking if I created my own routine then I wouldn't have to worry about the pause button etc. although I am still curious to what other opinions are.
