The member experience
At 9Round, our mission is making members stronger in 30 minutes, physically and mentally. To help us do so, we offer carefully-crafted levels of our member experience.

The trainer-led experience
A tried-and-true 9Round member favorite. During our Trainer-Led circuit hours, you’ll be guided and motivated by Champion Trainers as you move through the day’s workout. With the TLE, you’ll have dedicated time with a trainer performing traditional kickboxing and boxing combinations with various striking targets throughout your session.

Your entire workout will be fully customized to your fitness level and goals, and you’ll leave sweating and smiling. Personal Training sessions and packages can be purchased in-person at the studio.

The virtual experience
Work out anywhere, anytime with our on-demand fitness app, 9RoundNOW. Our extensive collection of online workouts harnesses the power of kickboxing fitness to help you crush your goals at home, or anywhere your device takes you.

What members are saying
"The trainers are very friendly and encouraging. Everyone encourages everyone else during your workout. You get fit while having fun and the trainers are very good at explaining what you need to do at each round."
What members are saying
"Nicole is amazing and has shown compassion and understanding with my son who has anxiety. She wrote down the exercises so he knows what he is doing. She is up beat and positive. The gym is clean and she sanitizes regularly. It has a welcoming and family feel. I have never seen anything like this. I have 2 sons that attend. My oldest would never go to the gym alone but feels so comfortable here. "
What members are saying
"I love the members and trainers! Everyone makes you feel like family, no matter if you are just starting out or have been there for a long time. It’s the best workout you can get, and it’s only 30 min! I burn at least 500+ calories each workout and it’s so worth it. I feel mentally and physically stronger every time I walk out of the gym. I look forward to my workouts everyday! :) "
