Sounds interesting. Right now, I'm still trying to find a proper plan to work with. I have a few excercises which seem to be alright, but I've only tried them three times so far. I found that it's actually fun, and it really helps you put your mind off things for half an hour. In fact, I even found myself looking forward to the work-out today. And although I'm quite exhausted right now, I feel really good.
The tougher thing for me is to find a proper diet. I don't have much cash to invest in proper food, or so it seems. I heard lots of nutrition gurus telling me it's not all that much about what you eat, but more about the regularity. Having a very irregular lifestyle as a student doesn't help, of course.
