  • 9Round is a fun, quick and yet challenging workout. Given my busy schedule, a workout that allows me to get in and out in 30 minutes while burning a high amount of calories is just what I need. The trainers are very helpful and the workouts change each time - so you never get bored.

  • I love that I get a great workout in 30 minutes and it’s not the same thing every time. I need the variety that 9 round gives me to keep me motivated to come back everyday.

  • The trainers! They are always showing me how to improve my technique. I also love that there is no set class time. Life is busy so not to have to plan my workout around a schedule is the best! The workout itself is a challenge as each day it changes so you don’t get bored doing the same thing! All around 9Round is the best!

  • That the workouts are constantly changing and there aren't set times like if you signed up for a class at a gym.
    - Oct 11, 2018 by D.S.
  • 9 Round is a great workout and feels like a community. The trainers are helpful and always take the time to ask my name and chat to get to know me if they don’t. I find it to be an encouraging environment too especially when the workouts get tough and I get a little intimidated, the trainers always encourage or offer modifications for my level while always pushing to get me to that next level. Great gym, very empowering.

  • I love 9Round! I've been going about a month now and not only is it the best work out ever, but everyone is so friendly! I was nervous at first that I would not be able to handle it or not know what to do, but the trainers are great they really help you learn the right technique and push you to get the best work out each time! Thank you Zach, Tim, Becky, Kendra :)

  • I began going to 9Rounds because I knew that I needed to make changes in my life and my health. When I started I had almost no prior exercise experiance but the trainers were very helpful in guiding me through each session. I know they have my best interest at heart and I dont feel like I am being judged but instead feel that they want to see me succeed and continue to encourage me to better myself.
