  • I like the friendly atmosphere. It's like a gym version of Cheers - where everyone knows your name. The work outs can be intense, but you feel awesome afterwards. So far I've lost 5 pounds, and probably an inch off my waist!

  • The program works really well for me in its convenience. Because of how easy it is to get in a workout completely around my schedule, working out every day is so much more attainable! That makes me not only look better but most importantly - FEEL better! Love my 9Rounds trainers more than anything, though. Even if they opened a new 9Rounds next door to my house, I would still only come to THIS 9Rounds! Love the people there, I consider them best friends.

  • 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!
    - Apr 12, 2018 by Lidia Slattery
  • Trainers are awesome and keep you motivated. It’s a quick and efficient workout. I always leave exhausted. Very friendly and clean environment. So happy I joined the 9 Round family.

  • 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.
    - Apr 2, 2018 by Melissa Frisoli
