I have found a great secret to having fun while working out - music. I put together 30 minutes of music to workout on the treadmill. Six songs that keep me almost dancing on the treadmill and two songs to cool down with. The music sure did make a long boring workout go fast.
A friend at the gym noticed my MP3 hanging around my neck and asked me what it was. I mentioned the music and she said she didn't have an MP3 but did have an old cell phone that would hold music. She couldn't find a cell phone signal booster for it so she got another phone. A few days later she was using that old phone as an MP3 player and was enjoying her workouts too.
