Mariah Treadwell

 Growing up as an athlete in Maine, I’ve always had a passion for movement. When I began Pharmacy school in 2014, I shifted my focus from sports to strength training. I fell in love with the process of building muscle, teaching myself about nutrition, and seeing results. 

I recently moved to Utah for a Pharmacist opportunity and to explore the west. Fitness has been such a huge part of my own life that I want to directly help people make sustainable progress and experience the same fire that I feel. I strive to empower people to physically and mentally push themselves to be stronger. To teach them to not fear food and diet culture, but to understand nutrients and how the body uses them. I work with clients both in-person and online, helping them reach their goals through nutrition and workouts. Fitness is a lifestyle for me and I’m motivated to be a healthcare professional who preaches the importance of it. I enjoy all types of training and consider the gym a playground for your body and mind. I incorporate bodybuilding, CrossFit, and high-intensity workouts with my clients. 
Outside of the gym, my fiancée and I enjoy all of what Utah has to offer; hiking, skiing, good food, and many midwest adventures

Real People. Real Results

Xcel fitness is honestly the best gym I have ever been to. I have tried other gyms in the past but I always came back to Xcel! The trainers and coaches always push me hard and are concerned about my growth and progress. All of the classes are great and every class I’ve been to has been amazing! I really recommend becoming a member here!”


The gym is always very clean and well maintained. They have also implemented great cleaning tools and tactics with COVID, ensuring that all of the equipment gets wiped down before and after each use. It has all of the equipment that you’d ever need. By far the best gym in Utah!”
