Kaylee Santanello2024-11-04Trustindex verifies that the original source of the review is Google. I’ve been training with Alex Fillman for 3 years and I can confidently say it has been a truly life-changing experience. From day one, he took the time to understand my goals, limitations, and past experiences. He helps me track and understand my caloric intake so much that my relationship with food has done a 180. He is understanding of the physical challenges in my career as a musician and has helped with injury healing and prevention more than any physical therapist I have seen. He takes the time to assure correct technique and your understanding of how your body works. Not only have I seen incredible physical progress, but my mindset has also shifted. I now approach challenges with a new sense of confidence and resilience. Alex emphasizes the importance of mental strength alongside physical training, and that balance has been key to my personal growth. All of the compliments I have given to Alex come from my years of experience with him but the same can be said of all of the trainers at Relentless Iron. They are the gold standard of personal trainers. The environment at Relentless Iron is supportive, motivating, and empowering. From the moment I started, I felt welcomed by a community that genuinely cares about my progress. I went from being someone who never worked out to signing up for races and strength events with other Relentless Iron members. Whether you’re a beginner or experienced athlete, the trainers and other members make you feel welcome. I’m beyond grateful for the transformation I’ve experienced and I can’t recommend Relentless Iron enough. If you're looking for a place to not only get fit but also unlock your full potential, this is it. Rebecca Georges2024-11-04Trustindex verifies that the original source of the review is Google. Alex is an amazing trainer. Funny as hell, hard negotiator of reps and really cares about my health. He really gave me a strong foundation. I always have his voice in my head telling me “you got this” or “keep going, one more” Michelle Marshall2024-11-03Trustindex verifies that the original source of the review is Google. Great place to meet all your fitness goals whether you are just a beginner like me or just need a little more support to meet your goals. Alex and all the trainers are very supportive and welcoming. There is a great atmosphere at the gym and everyone makes you feel like a family. Alex is always there for questions and to help you move forward. The staff at Relentless Iron keeps you motivated and accountable. Jen R2024-11-01Trustindex verifies that the original source of the review is Google. 5 stars because there wasn’t an option for 6. I didn’t know what to expect when I walked into Relentless Iron, but I am so glad that I did. I talked to Alex about my training goals, and he immediately went into action creating, not only a training plan based off of everything that we discussed, but also a solid nutrition plan to help fuel my body and workouts. He is dedicated to his clients to get the very best out of them, and his 1:1 coaching is superior to any other trainer out there. gerri hammond2024-10-25Trustindex verifies that the original source of the review is Google. I have only been at Relentless Iron for a few months but I am learning so much about fitness and nutrition that I couldn't get at a big box gym. I have worked with Alex and other trainers there and they are all amazing. They know how to challenge clients to do things they think they can't do. Additionally, being the mom of two kids who play multiple sports, my schedule is always changing. Alex has been great about being flexible and fitting me in as my schedule allows. Searching Something2024-10-24Trustindex verifies that the original source of the review is Google. If you are looking for a local gym where the focus will be on you and your individual goals, you have found the right place. Alex and the staff at Relentless Iron will work with you to identify your goals and to develop a plan to help you get healthy and fit. The gym is a family owned business dedicated to focusing on the individual needs of the members. It has a boutique-style gym feel with lots of equipment to meet your fitness needs.

I highly recommend Alex for all your personal training needs. Alex is the best personal trainer I’ve ever had. He is extremely knowledgeable and attentive to your needs. His plan fits to your specific needs and goals. You will gain knowledge and grow a lot from your experience with Alex. Valerie Tomino-Entrot2024-10-23Trustindex verifies that the original source of the review is Google.
