I love spin classes. I'm also very big on music, so I make a mix on my iPod that's 45 minutes to an hour long of music that pumps me up so I know how much time I've been at the gym without looking at the clock. Put your favorite songs towards the end of the mix, so this way you keep going until you hear your favorite song.
