Hi, my name is Karen and I am a fitness professional in the Irvine area. I have been working out most of my life and decided to give my gift of training and nutrition to others. I enjoy being able to help individuals reach their fitness goals and to maintain them. To see the excitement on their faces as they strive to be fit and healthy, is a delight to me.

    I am writing you to express my sincere gratitude for all that you have done for me. You have literally changed my life. When I came to you...I felt like I was giving up on life. I was weak, off balance, depressed and extremely overweight. Today I am virtually a happier person, 50 pounds lighter and feel great. You are my hero and I have and would always recommend you to anyone. You not only have a fantastic ability as a nutritionist, but a wonderful caring attitude which radiates and gives others hope.
    Over the years, I have read self-help and nutrition books on health and fitness and have tried many eating and exercise programs with some limited benefit, but have never been able to put it all together and fully realize my health and fitness goals. I would highly recommend working with Mimi’s program. She teaches you self-control, good eating habits and is there with you every step of the way!! She stresses the importance of holding yourself accountable for what you are doing to your own well-being. With her patience and guidance, I learned to share my struggles and open my eyes to what I needed in my life to be healthy and happy. It will be an investment in your future that you will benefit from for the rest of your life!
    It is with great pleasure that I write this testimonial letter.... I weighed over 200 pounds when I started with Mimi. Today I stay within 160 to 150 pounds. I still fall back into bad habits from time to time, then I regain composure with the knowledge I gained with Mimi’s program. I am a stress eater and have struggled with the loss of a loved-one and the tensions and sadness of watching another loved-one with addiction - all since meeting Mimi. With her support, I have better health habits which have helped with my weight stability, stress and depression. I frequently get compliments on my new thinner shape, and I credit Mimi. I wholeheartedly recommend Mimi’s program for life-long results!
    Thank you again for helping me learn how to make healthy choices!!!!!!

    Hi Mo! Thank you so much for allowing me to upload your testimonial to my Idea site. It was truly my pleasure to help you to reach your fitness goal. You came to me at a time when you were truly down and going thru so much in your life between caring for your mother and addictions in the family. I knew that if you could work on yourself then you would be available mentally and physically to work with your family. And you were determined!!! I am so happy that you are happy! The weight loss and talks we had totally transformed you. And YES you are truly a happier person who looks at life differently. Thanks for allowing me to guide you in this process! I will always be here for you!!!

    Testimony for Right Choice Fitness

    Three months ago, I was introduced to Right Choice Fitness’ virtual training capabilities. At first, I was VERY hesitant. I don’t exercise like I should. I usually prefer a class so that I can be in the middle or back and go at my own pace. I certainly wasn’t one of those people that had a personal training telling them to crunch or bench press more.

    I’m also not so motivated to pick one of the millions of you tube classes and start exercising. I’ll always choose Netflix. I need a person directing the exercise – LIVE; BUT the thought of a 1 on 1 class, didn’t sound appealing either. Well, I was wrong.

    Right Choice Fitness offered a free demo personal trainer class through Zoom. I was hooked. You see, I forgot about the “personal” part in trainer. It was absolutely catered towards my ability, while “gently” pushing me to achieve goals. I’ve been training weekly with Right Choice Fitness for over 90 days and I’ve really appreciated it.

    Here’s the best part for me! I’m a single mom with a 7 and 5 year old. Getting out to exercise is impossible. Even those gyms that have child care don’t usually work. By the time I pick the kids up from school, we barely have enough time for homework and dinner. Right Choice Fitness works with my schedule. For me an early morning workout, where I finish as the kids are waking up is ideal. Right Choice Fitness is also flexible with adequate warning to change my schedule.

    I’m so grateful for Right Choice Fitness. It provides a great workout, right here in my living room! Priceless!

    Thank you so much Carol for allowing me to add your testimony to my site! I thank you so much for continuing to trust in me with your journey! You have been with me a long time and due to life circumstances you have to regroup but you still come back when you are ready. Now that you have your two lovely children, the virtual workouts are working fantastically for you! I am so proud of you for continuously maintaining your health and wellness and allowing me, as your trainer, be the one to guide you!!! HIGH FIVE TO YOU CAROL!

    One of the best decisions I made was to invest in the health and well being of my mother in addition to my own. During this COVID 19 pandemic, I knew I needed to do something that would be beneficial to my mind, body and spirit. During this shelter in place directive, neither my mother nor I, were as active as we had been previously. I was interested in hiring a fitness expert who had years of experience. I contacted Karen at Right Choice Fitness and she customized an excellent workout program for each of us. On my training days with her, she leads Tabata exercises, which are incredible, as well as strength training - plus she always figures out a way to get some dance moves in because she knows how much I love dancing. My 76 year old mother's personal training is focused on building muscle strength and on developing her equilibrium through chair exercises. I have been so pleased with the results. I am more enthusiastic than I have been about working out in some time and I really see the results. My mother, overall, has more energy and she truly looks forward to her online class with Karen. Much of that is attributed to Karen's level of care for her as well as possessing a truly amazing personality.

    Thank you Michelle for allowing me to post this testimony from you and your Mom! I totally enjoy being the VIRTUAL trainer for you both. It is truly my pleasure to watch you reach your fitness goal especially having such a high stress job. And then later in the day, at her convenience, it is so great to train your mother with weights. Some days we sit, some days we stand....but it's all based on how she is feeling! And she totally enjoys it and always has a big smile on her face. Michelle, you should be proud of her getting STRONG! You both are such an inspiration to the fitness industry!

    Wow, what a difference...

    What a difference Karen’s bootcamp classes have made in my life! Yesterday, I ran into my "usual" store and picked up 2 pairs of pants — size 14 — I’ve worn for the last couple of years. In a rush the next morning, I put a pair on, expecting to rush out the door. The pants were just too big! In my Waist!! I needed to go down 2 sizes!!!"
