There’s a lot you can do to tone your body from the comfort of your own home. For example you could use your couch to get 6-pack abs in 6 minutes, or use a quarter to tighten your stomach. Since you'll likely have to do more than that for overall health, why not use your iPod to plan your workout and set goals?

"With TrailRunner you can plan workout routes on a geographical map, export the route directions as small NanoMaps onto an iPod and import working data from the Nike + iPod sports kit back into the workout diary. Other features are an exercise plan, .Mac weblog publishing, a GPS, GPX, and KML Import/Export and an integrated map and elevation data download from global mapping services like USGS togo maps."
