Mary's Journey<br>Mary wanted to start a walking plan but did not know how to begin. She went online and researched walking for exercise. She spoke with a trainer at the YMCA who helped her write a plan. Mary started out walking one block per day, for one week. By the end of the month, she was walking four blocks.
Mary was over 60 years
