If you are debating missing a workout session then take a look at this amazing woman for motivation. Ernestine Shepherd, of Maryland, started weight training at 71 and has not stopped since. Now she is 75. She is the Guinness Book of World Record holder for the oldest bodybuilder and attributes consistent physical activity, including a daily 10-mile early morning run, and a healthy diet to her success. When she was 56 her sister and her attended a picnic where they wore bathing suits, but after seeing how badly she looked in her outfit she decided to begin exercising. Take a look. Enjoy.
