Ryan Dart's passion for sports started when he was five years old and continued through his college rugby career and beyond. After trying his first CrossFit class, the positive experience had Ryan hooked. Now this dually-certified CrossFit and weightlifting coach shares his knowledge with clients at his own gym, CrossFit Appleton. Ryan adapts CrossFit's scalable approach—which is used to train military personnel—to people of all fitness levels, from cage fighters to the elderly. Both he and his fellow trainer, Marie McCarthy, often encourage their students to go on a Paleolithic nutritional plan to achieve maximum results. This no-nonsense approach to eating cuts out carbohydrates such as sweets, sodas, and delicious looking wax fruit.
