  • My favorite part about 9round is the sense of community. Trainers and members treat you like you are family. We motivate and hold each other accountable. When it looks like something is too easy for me, Rick and McKenna add weights or challenge me. The music is usually awesome, and I do make requests! People say it is a little pricey, but for the personalized experience and fact it is 2 minutes from my home it is totally worth every penny. I love my 9round fam and will be a member here for a very long time. They have changed my life. I joined May of 2017 and have dropped almost 3 pant sizes without any insane dieting! They believe in healthy and fit and appreciate all body types and sizes. Very rare to find in a gym ❤

  • Quick in and out workout starts when you get there and our trainers!!!!! They’re the best!!!
    - October 04, 2018 by I.N.
  • I appreciate that it caters to people at all levels or capabilities. I was in a bad car crash which has hindered certain functions of my back and knees and I am still able to participate at the same speed as everyone else. The trainers replace some of the exercises with something that I'm able to do. I leave there drenched in sweat every time. My friend and I usually go together, but I have gone by myself also, and it was fine. You move in such fast paced intervals that there isn't time for socializing anyways. I feel like I get a good work out in only 30 minutes.
