TESTIMONIALS

Some
Kind Words

"Amy is such a great personal trainer. What I really loved about working out with Amy is the variety and how fun the workouts were. Every workout is challenging, but it is the perfect the level of “challenging” where I’m not too sore, but feel super strong."
- Liubov
"Amy is the bomb! I had not worked out like I used to since Covid. She gave me confidence, pushed me when I needed and made me laugh. I had a torn meniscus and she rehabilitated my knee with exercise. Don't hesitate! Train with Amy - you will not regret it."
- Nissa
"Amy is great! Not only did she help me identify the cause of some fatigue issues and suggest supplements to help but also got me back on track after getting Covid halfway through marathon training. Loved the tailored workouts, the fueling advice, and all the support she gave throughout every step of the way!"
- Katy
"Amy is friendly, easygoing and positive! I really liked having her encouragement and felt completely comfortable with her, too."
- Gretchen
”Amy is FANTASTIC! I started seeing Amy when I had a leg injury. She gently trained me back to health being super mindful and comforting yet still strong and supportive. She is a great personal trainer. I’ll continue to work with her. She’s the best!”
- Shantee
Amy is an amazing trainer who provides personalized support, guidance, and motivation. Her holistic approach to fitness and healthy living has made a truly positive impact. She goes beyond workouts to help clients build better habits and feel their best. I’m incredibly grateful for her support!
- Gina

- Julie
Amy is an amazing personal trainer! Her creative workouts, fitness expertise, and attention to proper form make every session effective and enjoyable. She is kind, motivating, and always believes in her clients while pushing them to improve. I highly recommend Amy to anyone seeking a true fitness professional!
- Mamata
"I have been working with Amy for almost a year, and she is amazing! I am a runner, so I went to her to rehab after an injury... and prevent future injuries. She has been successful with both, I am happy to say, and one year later I still get sore from her ass-kicking workouts! An additional bonus is her commitment to client comfort during COVID!"
- Becca
"I found Amy as a trainer to help me with my running. She was very professional and knowledgeable. I started improving very quickly. She was easy to keep in touch with and always had my workouts planned out on time. if anyone out there wanted to become a better runner, I would not hesitate to recommend Amy as a coach."
- Heath
"Amy has helped me train for my goal race this summer and I've never felt stronger! Each weekly set she prepares focuses on areas of weakness and we are building towards better strength and form specific work towards this goal. She is also a wealth of information for diet and other lifestyle variables. I look forward to see what she has in store each week!"
- Andy

"I would highly recommend Amy for your personal training needs if your goal is to get results. Her rates are so reasonable for the high level caliber training she provides. I am an avid runner, ran DI XC and track in college and I feel like Amy is elite when it comes to personalizing a plan. She now lives out of state and does convenient online training. Thank you Amy!"

"I've never known a trainer to care so deeply about the results their clients see. Amy goes above & beyond constantly. Her focus on her own health proves that she walks her talk, which is the most important quality in a trainer. Amy is one of the few people I trust to train me. She is incredible!"
- Kanyon
"Amy is amazing inside and out; she has changed her life tremendously and become exactly who she was meant to be.

"Amy is the best! I've seen so much progress in my running since I started working with her compared to when I was training with cookie-cutter plans and apps I purchased online. I'm faster, stronger, and seemingly less injury-prone. She pushes me to do harder workouts than I would attempt if I were still solo training (which is paying off!) Highly recommend!"
