  • The trainer are the nicest and most motivating trainers I’ve had. I love that their is no class time, being a working mom with 3 kids it’s makes it so much easier and less stressful not to rush to a class and pop in when you have that extra time. 9Rounds is my happy place. Jessica

  • My trainers are personal, they take an interest in my fitness journey...if I need that push to do one more sit-up or a kick needs to be modified according to my individual abilities they notice and adjust. I walk out energized and ready to take on the day. During the time I have been with 9 rounds, I have become stronger both mentally and physically...No excuses!

  • Knowing that the workout is already planned out, and there is no scheduled times.
    - Jun 2, 2019 by Jeff Dennis
  • Everyone is very friendly, and also I like about 30 minutes work out, I do stop by when ever I want, no time schedule which I heat. And also this gym price is really good. And if I want to go different gym, with this flexible time, with personal trainer, would cost me a fortune! So this Gym is all in one place to go.!

  • 9round has wonderful coaches who are knowledgeable in boxing, kickboxing, and in basic body movement and mechanics. The coaches are patient and willing to put up with newbie questions such as, "How do I do this movement, again?" to "I'm not doing this right, am I?" when asked multiple times over. They will even go as far as to pressing the "restart" button with a client when one goes punch love crazy. In addition, one of the best attributes of 9round are the coach's ability to work with clients who have mobility issues and prior athletic injuries. Best of all, they go out of their way to make their clientele feel welcomed. Furthermore, its' always nice to want to go back to a gym where your coach's goal is to push you to the point of upping your game and gain. I will continue to go back for another round. Thank you for your patience, knowledge, respect, and hard work.
