Working with my trainer Chris has been nothing short of transformative. From the very beginning, he took the time to understand not just my fitness goals, but the unique challenges posed by my injuries. What sets him apart is his extraordinary care and attention to detail. Each workout is thoughtfully tailored — striking a perfect balance between pushing me to my limits and protecting the areas that need healing.

His expertise, patience, and genuine commitment have kept me motivated and consistently progressing. I’ve felt stronger, more confident, and well-supported every step of the way. He doesn’t just train bodies — he empowers people. I’m endlessly grateful for the care he puts into every session, and I truly adore working with him.

The best decision I have ever made! The one on one personal training really takes into account your abilities and needs. They challenge you to do a little more each time, but not to the point of overdoing it. Everyone is always available to answer your questions too.

I wanted to add that a big shout out should go to the trainers. They have the patience needed when working with clients with any sort of disability. You can see the professionalism they have as well as the care they provide to each and every person that comes through the doors. Keep up the great work!

This is mostly a personal fitness training type of gym. It is great for P.T. needs. Not sure about O.T. but most likely. Staff is very friendly and knowledgeable. I take a client here and we usually see Rick. He is awesome! We also got to train with A.J. who is also great and Gigi as well. I would highly recommend them if you have any type of sports injuries.
