work out

Somehow my apartment has a small gym. Actully I had almost never used there befre because I am not interesting in working out. However, I am using there with my roommate nowadays. It takes 20-30 min a day. As I am running on a machine, I listening to music with ipod. Even if I try to make work out fun, it is very tough anyway. Every one minute I really want to give up, but I do not, because my roommate is still running. I feel it is like a competition. I do not want to be a looser so that I am always exhausted evey time when we work out.
