    Amy Jo, 55 years young

    In 2014, at the age of 48, Amy Jo joined CrossFit Roots after moving from Atlanta. An athlete at heart, CrossFit was new to her. She used multiple bands for pull-ups, could not kick up to a wall, and weightlifting was a new endeavor for her. Fast forward to 2024, and Amy Jo finished 14th in the world at the Masters CrossFit Games in the 55-59 year old age category. She completed bar muscle-ups, walked 80 feet on her hands, and front squatted 205 pounds. Learn more about Amy Jo, her work ethic, her career, and her family.
