  • Being someone who has not worked out in a long time to this capacity, the staff is incredible about taking each step slowly with me. I don't feel intimidated by the workouts and I am enjoying everything about my experience.

  • What I think I like best about 9 round is that it keeps me coming back for more. A lot of the workouts are so fun you don’t even realize that you’re working as hard as you are. It’s a fast but intense workout, so you can fit into your schedule and it’s worth the effort. The trainers are dedicated and friendly. 9round has changed my outlook toward fitness. I have finally found something I enjoy doing.

  • I love that the coaches know everyone's name and because of that, it becomes a very personalized experience. I never feel alone there. It is also the only gym I have ever joined where I look forward to going in. For the first time I can say I have been going to the gym 3-4 times a week consistently. And I am seeing results!!

No need to think about what you plan or want to do on your way there. It is also a great workout and easily fits into busy schedules.

I love that every day is a totally different workout and I never have to think about what to do. The workouts are demanding but fun. Jesse, Carolyn and Jessica are always there to show you what to do and motivate you to push your limits! I look forward to my workouts every day and joining 9Round was the best decision I ever made!
