  • There is nothing like 9 Round! I recently went on vacation where no 9 Round was available and had to go to a regular gym. I did not get the complete total body workout I always enjoy at 9 Round. And, I missed having the personal trainers there to motivate and guide me. 9 Round is the best possible workout for me and I will continue to recommend the gym to everyone I meet!

  • My coaches are the best in the world! Physically getting to the gym or a workout class is arguably the hardest part (for me, personally), but with 9Rounds, I am psyched as heck to get there and see my people! And the workout is hard as heck every. single. time. But my body craves it. 9Round was the best decision I ever made.
    - April 02, 2018 by Melissa Frisoli
  • Everyone is really supportive. I have the best trainers with Iryna, Cat and Caroline!!! No scheduled class, you can go at anytime. Also the workout is never the same. 9Round challenges you!
