  • 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.

  • 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 like the personal attention I get with the trainers. They are always there to make sure I am using correct form and pushing myself to the best of my ability.

  • 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.

  • 9 Round is awesome and I’ve never been happier with a gym membership. Being able to get a complete workout in 30 minutes with fun instructors and new exercises daily makes it easy to get myself there as often as possible.
    - August 15, 2018 by Clint Maclean
  • 9Round is just awesome! Once I was the last person to visit any gym, I hate those big machines in the gym and they never motivated me, though I wanted to join a fitness regime for overall strength buildup. While browsing the internet I came across 9Rounds. After visiting them and taking a free workout, I was sure this is the place I want to be.Finally me and my husband both joined.The owner Brad and Nicky are very sweet people.Also, the other trainers are very good and motivates you every time during your workout. I just love their overall fitness structure and it only takes 30mins of your day to burn 300+ calorie and the best part you can visit them any time in between their opening and closing time. I really enjoy all the 9 rounds with different exercises which includes weights, kickboxing, cardio etc., changing everyday.

    - July 26, 2018 by Jill Ramirez
  • It’s a fun way to get my cardio in. I used to despise cardio so wouldn’t do it. The gym is clean. The trainers are nice and encouraging. I love that it only takes 30 mins yet I’m drenched in sweat and no I actually did something. I also love there are no class times which makes it super convenient for my extremely busy life.
    - July 25, 2018 by Dawn Brooks
  • Love the 30 min workout and that there are no set workout sessions. Being able to jump in whenever I get there is helpful

  • Each round everyday we get to do something new, which is a surprise element in 9 Round. I love it
    - July 20, 2018 by Sangamitra Sengupta

    - July 15, 2018 by Crystal Patterson
  • It's always a fun and challenging workout and I don't have to think about what I'm going to do when I get there. It's already programmed and I don't have to make it to a class time.
    - July 13, 2018 by Aaron Headley
  • I love the flexibility of the class and showing up and jumping in when I’m ready. I like the variety of the workouts and that I can work really hard for 30 minutes and move on with the rest of my day. Great coaches at my location as well. I really enjoy going to class.

    - June 13, 2018 by S.L.
  • I have finally found a place where not only is it convenient for my work schedule, never over crowded, and the best is that you always have a trainer showing you the correct techniques and they motivate you. I have a very busy schedule but make time to come to 9 round cause I know I’m going to get an efficient workout and have fun most of all. I get excited to workout which is something I never loved to do.
