Mary Frith enters another year as a Personal Trainer at the University of Chicago in the 2025-26 academic year.
After hitting burnout from years of competitive cross country running, Mary Frith found her way back to enjoying exercise once she became licensed as a Zumba instructor. From there, she became certified as a Group Fitness Instructor and Personal Trainer. Mary has trained clients with a broad range of goals, including general fitness, weight management, muscular development, and sports performance. When she is not training clients or teaching fitness classes, she is an MD/PhD student studying metabolism and gut health. In designing her training programs for clients, she takes an integrative approach, working on balance, core strength, cardiovascular fitness, and full-body strength. All in all, Mary is dedicated to helping clients enjoy exercise, build confidence in their own strength, and guide them to reach their fitness goals and more, both safely and sustainably.
