I want to buy a gym bag, and it got me to thinking what others bring with them to the gym on a regular basis. I just got an ipod and love it (with the armstrap thingy.) I also have my heart rate monitor. I usually bring a book, my water bottle, but I didn't have a comb today. I'm thinking a small makeup bag would be good too, though I often come straight home (though I went food shopping today.) I don't plan out my days well. I'm thinking some form of food would be good, and chapstick and lotion, etc.
So, do you have any interesting stuff in your gym bag?
