Client Testimonials

Helene E.

One of the best things that happened to me this year was being introduced to Ariana Jewelewicz. I’ve struggled with stomach issues and gut inflammation for years, and nothing seemed to truly help.

After my initial consultation with Ariana six months ago, I immediately knew I was in exceptionally capable hands. She was completely honest from the start that getting well would take time, and that honesty alone was refreshing. Her expertise in nutrition, health, and wellness has been truly invaluable. She carefully reviewed my medications and encouraged me to discuss changing them with my doctors, since they were likely contributing to my gut issues—and what a difference that has made. Her guidance on which foods to incorporate and which to avoid has also been incredibly helpful.

I cannot say enough wonderful things about Ariana. Anyone would be fortunate to work with her.

Ariana is not only exceptionally dedicated to her clients, but one of the most passionate people I know in this industry and space. She is constantly expanding her area of expertise and certifications. Her commitment to this lifestyle and her desire to share her knowledge with her clients makes her a truly special trainer. I personally use Ariana‘s training and nutritional services and have recommended her to everyone in my circle. Hands down the most dedicated and knowledgeable trainer you will work with.

Ariana has done so much to improve my health! I'm 65 and have one of the most unhealthy jobs in the world. She has designed a diet and physical routine talored to my crazy life. I can be in Alaska or the Caribbean and she answers my text quick when I need to make healthy choices. I've lost 36 pounds and continue to improve my life, thanks to her!
Vanessa M.

Ariana is a fantastic personal trainer. She has so much knowledge about proper training form and lots of tips for making each exercise more beneficial and safe. I'm 62 and I have 2 bulging discs I didn't think I could accomplish the things that I have but she has taught me so much and she pushes me just enough to see changes. A bonus is she is an extremely knowledge nutritionist. Knowing how to eat to lose fat while gaining muscle is a big part of our training. Plus she's such a sweet person, she makes you feel really comfortable. I highly recommend her services.

Ariana is worth every penny you spend with her! It has been so hard for me to achieve my fitness goals without subjecting myself to an impossible lifestyle routine that always ends with me binging and burning out. Ariana taught me how to lose weight while feeling energized and well-fed instead of before when I would be fatigued and starving 24/7. She also showed me how to optimize my workouts so I could gain the muscle I wanted. I highly recommend her if you are looking to be the healthiest and happiest version of yourself through your fitness goals.

I’ve been on a Weight loss program this year and so far I’ve lost 20 pounds. I’ve ate all the foods that my nutritionist Ariana told me to and I’ve done the exercise program.

Ximena T.

Working with this coach has been one of the best decisions I’ve made for my health and fitness. I’ve gained lean muscle, lost excess fat, and feel stronger than ever.

Beyond the visible transformation, the way I feel has completely changed. I have more energy, my mood has improved, and I’ve developed a much healthier relationship with food. I’ve learned so much about nutrition and how my body works, especially the science behind it, thanks to the coach’s incredible knowledge of physiology. They always take the time to explain the ‘why’ behind every recommendation, which has helped me make smarter decisions in and out of the gym.

Having 24/7 access to a coach who genuinely cares about your progress is priceless. If you’re looking for someone who will not only help you achieve your fitness goals but also educate you along the way, this is the coach for you. Highly recommend!
