I love to use pedometers to measure how far I walk each day. Since I do not go to the gym I aim to walk at least six miles on my daily walks. If you are not used to walking you should start out walking a quarter of a mile. Also, always ask your doctor before starting a new exercise routine. Walking is a very good form of low impact exercise though, so I highly recommend it. I always have fun seeing how far I walk each day, and keeping track of my results.
