  • I came to Transfitnation Gym with the goal to pass a fitness test. With no athletic background I was able to reach my goal in 6 months of training. All trainers are great, went all out to help me achieve results, very helpful, answered any questions I had, gave me advice on a proper nutrition and diet as well. Sterling my main trainer- thank you so much! I couldn’t be happier with the transformation. Absolutely life changing experience. Thank you All!

  • Like a lot of other people, the pandemic did a 'number' on my body. Working from home, snacking all day and sitting around caused me to be the heaviest I ever was in my life. With the help of the guys at Transfitnation, I have made great strides in fixing of this situation. They are very thorough, creative, encouraging and knowledgeable when it comes to fitness and training and actually make it enjoyable to go over there. They tailor their training regimens and it's my impression that they don't just simply use a cookie-cutter approach of bench-presses and arm curls like most other trainers might do. I highly recommend Transfitnation and while I won't get into specifics (not just my weight, but other important metrics), the proof is in in my numbers. As the trainer Stephan might say - a membership at TFN would be an 'excellent adjustment'.

  • I joined Transfitnation’s group class and had a fantastic workout! The trainers did a great job tailoring each exercise to different fitness levels in the group and keeping everyone engaged throughout the class. I’m also a part of the Transfitnation step tracking challenge and I love that they’re giving back to the local community (and keeping me motivated to move more 😊). I highly recommend Transfitnation to anyone looking to get in shape with this group of knowledgeable personal trainers.

  • Really great group of personal trainers. I started training with the owner Steven many years ago. He is a great guy and an excellent trainer who really cares about his clients. For the past couple of years I've been training with Sterling who is also a fantastic trainer with a great personality and a lot of dedication to the people he trains. I've trained with other trainers in the company as well and everyone is friendly, knowledgeable and great at their job. You can't go wrong with this group!

  • I have had bad experiences with trainers before, so I really did my research when I decided to hire a trainer. I decided to go with Transfitnation after speaking with many trainers. I was paired up with Stephan. I knew from the first time I trained with him that he was going to be my trainer. Stephan cares about my goals and he listens. I want a trainer that cares about form and willing to push me to my limit and he does just that. He brings the much needed energy to every workout even when it is at 6 in the morning. Overall I am very satisfied with Transfitnation and highly recommend it to anyone who is thinking about hiring a trainer.
