  • 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.

  • 9R has been the one “gym” that I’ve really enjoyed. Even after life happens and you find that it’s been a few months, you’re welcomed right back. I’m looking forward to jumping right back into the swing of things.
    - Nov 28, 2018 by P.J.
  • The coaches are friendly and fun! You can really tell they care about you as a person. You never do the same workout and you get to push yourself at your own pace.

  • No class times! Fast paced and fun

  • Cardio for me is torture and feels like you’ve been on the treadmill forever (but it’s only been 2 mins). 9round is actually fun and it goes by so quickly.

  • I absolutely love the concept of 9Round. Every workout is amazing and so are the trainers. I love my Union Hills trainers they are the best and they make you want to keep coming back. I feel better and more energized throughout the day. This is the first place I tried that they build ban experience and keep you coming back to meet your goals. They genuinely care. I couldn’t be more pleased with my progress and friends and team 9Round has created.
