"I have worked with Mariah for many years, beginning when she was with another organization in the Chicago area. While Mariah's expertise and knowledge are truly world-class, it’s her passion and dedication to her clients that set her apart. At over 40 years old, I’ve been able to achieve personal bests in my lifts and lose over 30 pounds this year, all thanks to her guidance and unwavering support. Both personally and professionally, I cannot recommend BodyByMariah highly enough." - John M.

"I started working with Mariah in 2017 while she was training at another gym.  I was solely a runner, and desperately needed to build muscle in the off-season.  Fast forward to 2021, and I had more muscle than ever (but weighed the same, and my size went down).  By adding 3 days of power lifting to my schedule, which already included 4-5 days of running, I was able to get faster and finally beat my marathon PR, a time that I achieved in my first marathon in 2009.  The benefits go beyond aesthetics.  I'm stronger, which means my body feels better in day to day life.  I recover from my lifts and runs much faster than I did before.  And my running form isn't suffering by mile 20 because my back is strong enough to keep me right where I need to be.  When other runners ask what my secret is, I tell them they need to lift heavy shit." - Julie D.

"I first trained with Mariah in September of 2017. She holds a strong presence as a powerful, motivating, educated and badass trainer. Mariah takes time to get to know and understand her clients - their goals in and outside the gym, because the goals you work on in the gym often translate outside of it: confidence, consistency, persistence, motivation, and dedication. I had the confidence to go in the weight room for a workout but Mariah has helped me to more strategically approach the weight room for my lifts. I’ve also built up more confidence to tackle heavy barbell lifts, with proper form, that I might have only approached when working out in a session with her by my side. Mariah has built deliberate programs that have helped my performance over the last 6 years: finishing multiple marathons while maintaining strength, getting my first chin up (and now multiple sets of them), and even to compete in my first powerlifting competition. She is well versed in strong performance for her clients.Mariah is reliable, driven, trustworthy, well educated and celebrates every victory and milestone of her clients. It’s clear to see that this is her passion and she has brought that same passion out in her clients." - Charlotte C.

"I started working with Mariah a few months after having my second child. I had always taken workout classes, but I was nervous to start doing them again for fear of injury, especially since my pregnancy had made my chronic back pain worse. Working with Mariah was a game changer. It is clear she has years of experience, and is trained in how to work with someone who gave birth and who has back pain - she is the real deal. She always listens to my body, never causes pain, and all the while is able to make me stronger and stronger. If an exercise isn't working for me, she knows how to tweak it. She is very engaging, easy to work with and motivating. Time always flies when we are working together." - Kathy C.
