  • Great overall workout - you definitely get your heart working and move EVERY muscle! Trainers are awesome, and you're done in 30 minutes! Can't beat that with a stick!

  • As a customer, I look forward to the ever-changing workouts and the inspiration I garner not only from the trainers but also my fellow 9Rounders. There is a real sense of camaraderie amongst all participants which provides the much-needed energy to meet the challenges of the workouts. As a business owner, I appreciate the professional manner in which the business is operated and the training/thought that goes into every aspect of the 9Round experience. All customers are treated professionally and the culture is respectful while maintaining a personal warmth. Excellent in every way! Jesse Mahle

  • I love the family atmosphere, the individualized workouts to push you at your maximum instead of a one style workout for all, 30 minutes and I’m exhausted and drenched so I can always usually find the time.

  • I really like that the workout is 30 minutes. And in that 30 minutes, I workout harder than I would by myself during an hour long workout.
    - July 15, 2018 by A.E.
  • The best thing I personally like about 9Rounds is that you can get in a quick round of cardio in while releasing tension/stress through kicking and punching. Although, challenging, it's also a fun workout that changes everyday which keeps your interest. Never the same. Overall, it's a great concept!
    - July 15, 2018 by J.H.

  • I love the personalization of the workouts. If there is something you need to modify, the trainers are there to work with you on those modifications and offer suggestions on how to change it up. There is never a time you don't feel like a part of a community.
    - June 04, 2018 by Allie Kimmel
  • The staff is always upbeat and encouraging. Whenever I go, I know I am going to get a challenging full body workout that allows me to work at my pace, however, challenges me to keep pushing.

  • It is a fun and hard workout that leaves me sweating, exhausted, and exhiliarated!
    - April 04, 2018 by Robin Sexton
  • There is nothing I don't like about. I am not a gym guy and hated going to the bigger gyms because you felt lost not knowing what to do. At 9 Round its more like family and friends because all the trainers know you and you become friends with the other people working out. The 30 minutes goes by very quickly and I have seen great results from my time there. Wish the hours were a little better between work and kids but I make it work. I look forward to continuing my work outs there and I upgrade to Mike 3.0.
    - April 04, 2018 by Mike Yowaiski
  • I enjoy the convenience of not having to scheduled a time to workout. As a runner, I enjoy the workout because it gives me the cross training that I need to improve my running. I also appreciate the motivation provided by the trainers.

I transitioned my love of actively participating in sports to teaching and training basketball to high school basketball team members and neighborhood kids. This lead to an assistant coaching position for a girl’s high school basketball team. Later I obtained my personal training certification and worked as a personal trainer.

I was introduced to 9Round, and loved everything about it. From the Full body workouts in 30 minutes, to the No Class Times, and with a Trainer included. I look forward to helping you reach your fitness goals 9Rounds at a time.”
