  • After finishing my first trial at 9Round Cornelius in January this year, I was left with no doubt that the 30-minute boxing workout is tough and designed brilliantly. The combination of cardio, heavy bag boxing, kickboxing, conditioning and core drills et to a three-minute timer helps keep me moving while challenging your body in just 30 minutes. On top of that, there no waiting for a class to start. With my work and life schedule, I can show up whenever I can and dive straight into the day’s pre-planned workout developed by the coach-du-jour. Workouts are tough but achievable. I can slow down or speed up my pace or incorporating modifications of my own to make it more fun. Trainers are very knowledgeable about the fitness aspects, staffs are friendly and highly motivated and energetic individuals. I love this place.

  • 9Round is what I think about when I think of the perfect gym. It started with the location, it is so close that it’s hard for making excuses not to come in. It quickly moves to the awesome energy and knowledge that you get from the trainers here, they are eager to help and will to take time with you. Best of all they understand what you are striving for and they will get you there and further, while having fun.
