The couple's goal was to create a fun, unique, and effective fitness experience that would help people of all ages and fitness levels get in shape and reach their goals. The Hudsons have done just that. 9Round has become one of the most popular and fastest-growing fitness franchises in the US, and today it has locations in more than 30 countries around the world. It's all thanks to Shannon and Heather's commitment to creating a unique and convenient workout experience that anyone can enjoy.
