I’ve trained with Mariah for 9 months now and am really happy with my results so far. She’s so knowledgeable and you can tell she really puts work in to make effective training programs! I’m so happy with how my features like my butt and legs have toned up since working with her!
I’ve been working with Mariah for more than 2 years and really appreciate how she is improving my overall strength, an important issue, as I am in my sixties. She pushes me to succeed, but in a careful way. She articulates what’s right and wrong and gives good direction on corrections.
As someone who has worked out alone the majority of their adult life I was nervous to be coached and assisted by a trainer, while also starting a workout program with my wife. Not only did Mariah make us feel incredibly comfortable and welcomed into her program but also has challenged and pushed us both physically and mentally. We always leave feeling elated, strong, and a little hungry — all necessary for personal growth.
I met Mariah in 2019 when she was training at Gold’s Gym in Hollywood. I immediately appreciated her calm energy and lack of intimidation in lifting. Mariah is fantastic—reliable and organized. She meets clients where they are and pushes them just past their goals without being oppressive. She made lifting something I looked forward to—self-care that built my strength.
It has been a goal of mine to train with Mariah ever since I saw my friends working with her, and now I can see why they love her! Her energy, expertise, and encouragement make every session something I look forward to. Each session leaves me feeling stronger—both mentally and physically.
Since I started training, with Mariah, 3 years ago, I have lost about 80 lbs. My A1c was 9.5. Now it is consistently less than 6. My lipids are normal. My blood pressure is normal. I am 73 years old. I used to take 9 different prescription meds. Now, I take 5 and my doctor is thinking of cutting back more. Mariah is fun, knowledgeable, organized, creative and easy to talk to. I consider her a friend. My son has schizophrenia and I am his caregiver. He takes classes with Mariah, with me. She is so patient with him. And I have seen how working out has helped him. I feel so fortunate to have found Mariah. She literally saved our lives.
