Walking

I walked to work yesterday. Just about two miles. In the heat. I really think an ipod will help me keep it up. I love to listen to my music and it distracts me as I walk. I don't have one yet so I just played music in my head the entire walk to work. I've been researching what type of music playing device to get. I thought I'd try a music subscription service, but I found out they were not ipod compatible. Any suggestions anyone??? I've been diligent about my circuit training at the gym three days a week. Now I need to add in my yoga. I've been chicken about taking a class and just doing it here at home with a video. Who knew it took such courage to be fit?
