Inspiring transformations from women empowered by TrainerMonica. Your journey starts here!
Monica has been a great guide and motivator in my path to a strong healthy body. In the beginning I realized how deficient my diet was, I was shocked because I thought I was eating good! Thanks for all the advice and support!
After major back surgery and months of PT I just wasn't getting back to that person I want to be. I have been working with trainer Monica for a few months now and am making amazing progress without hurting myself in the process. I can do more and more things that I have not been able to do for years and my really bad posture continues to improve as a major bonus. This is no longer about "getting back" to an old version of myself but rather a moving forward. If you think that you are too old or have had too many injuries to get better, maybe you just need some help from a good trainer like Monica. What have you got to lose?
There's no better personal trainer than one that lives the life style of fitness. Monica is an excellent example of health and wellness. She's well versed in weight training, cardiovascular conditioning and most importantly....nutrition. She get's 5 stars from this Ms Olympia.
Trainer Monica has saved my life!! As she said, "with you, I've got many fires to put out"! 🚒 I lost all of my muscle mass after my 2nd COVID. This one was COVID pneumonia. Thank God muscle has memory! With Trainer Monica's experience, she knew where to start and now I'm standing taller and getting stronger every day! I can't wait to see my future progress because she's the best! If you've been thinking about getting in shape but don't know who to turn to, come by the Lab, get your consult and start. You won't regret it one bit. Trainer Monica is your answer!
I joined Monica's program, and we worked together for 90 days. I achieved my weight loss goal during that time. I also learned valuable workout routines to restore the muscle that I lost during the weight loss phase. I found Monica to be personable, knowledgeable and easy to partner with. I highly recommend Monica's 90 transformation program, if you do what she tells you, then you will achieve your goals. She also will help you with your specific issues, as an example I really needed to focus on stretching. Monica assisted me with exercises that have really helped me in that regard. Sign up and you will not be sorry. I highly recommend Monica.
Training with Monica has changed the way I eat(more balanced), move(better posture) and feel(more energy). I'm a cancer survivor and DBF helped me recover strength so that I can lift toddler grandkids. Highly recommend!
I would just like to give a huge shut out to my girl Monica Lopez. Best Trainer in, Payson. From the moment she started training our class, Monica has shown an unmatched level of expertise and personalized approach that has transformed my fitness journey all together! Her innovative workouts, unwavering support, and ability to push me beyond my limits have not only improved my physical strength but my mental resilience
I wanted to share my positive experience with Trainer Monica at Diamond Body Fitness, in case it helps anyone looking to start their health journey or who feel stuck in their current fitness routine. I’ve been working with Monica for a year now, and I’ve learned so much about how to properly achieve my fitness goals. For example: Balance: Just yesterday, I was able to do squats on a Bosu ball while simultaneously performing bicept curls. Stamina: I can now stay on the treadmill longer than ever before. Mobility: I can hike challenging trials with confidence. I trust Trainer Monica completely, she never asks me to do anything that would risky injury and always explains the benefits of each exercise. Working with her has changed me forever. Cathy
Monica is very knowledgeable in her field of fitness and nutrition plus more. She assists you in form, proper weight lifting and stance. Monica is caring, uplifting and pushes you to push yourself. With her guidance and expertise, I am a better me!
