I known Matt Trimmer since his other gym and recently had gotten back into kickboxing with him here. I love the workouts that he puts together for the class, walking around and spending time on each individual and their needs. This gym … More is very friendly and I have met some pretty incredible supportive people in my class. They have helped me keep motivated and with each class that I complete, I just want more and more. I also love the 24/4 hour gym access, where you can work on bettering yourself on your own time. I love it here!

This studio is where I participate in a weekly cardio class. They offer so much more there including an open gym area, boxing classes and karate classes. Believe me when I say All ages and abilities are welcome!! Coach Trimmer is highly … More experienced, dedicated and an excellent trainer. He’s committed to his students and their goals and often becomes like family. This is a safe place for your kids and family to invest your time and money for your health and to learn new skills.
