Harry Potter goes to the gym?

I went to work out with Bong and Tsavos today, trying to take my mind off of things. In fact, I think that's what I like most about it because it really is a place that I can just get away from it all. Well it's that and the fact that some hot chicks work out there as well.
Anyway, about halfway through our workout I noticed something that seemed really out of place. There was a girl on an elliptical machine reading Harry Potter and the Half Blood Prince! Just when I thought I had seen it all, I noticed a few minutes later that she was with 2 other guys and one of them also had the book with him!
Don't get me wrong, I'm a certifiable Potter head. I mean I can't wait to get J.K Rowling's latest from my Tito Boy later this week (he works at the Amazon warehouse in NJ). But not bad enough that I'm goin to take it with me to the gym! That really threw me for a loop. Then again I shouldn't be surprised considering how many copies that have been sold already.
