  • It’s the push the guidance the sweat that drew me to 9Round and yes I will definitely refer my friends because the results will make them feel better about themselves.

  • I like how it’s challenging but not unachievable. Though it’s small, I don’t run into any routine workouts since they always switch it up. Since it’s small, you get to know who’s working there and they have a chance to remember your face vs walking into those big gyms where no one is familiar because it’s so many staff members

  • Its quick pace. and the personalization to the individual.

  • The close connections! The immediate push to do better!

  • I enjoy starting my days with my 9RoundBrooklyn early morning session before the sun is up. The trainers have great energy and motivates through every round. I look forward to the challenge of a new routine daily and the fun that mixed in between. The end of round 9 definitely leaves you feeling stronger.

  • Trainers are friendly and encouraging, no class times make it SO convenient, and I like how short it is. It kicks your ass but it's fun. Every when you're miserable at a station, it feels like it's always almost over, so you push yourself to work harder.

  • Great experience overall! Was visiting from out of town and wanted to be sure I got my workout in. These guys were great! Very attentive to each individual at all rounds to assure everyone has proper form. Pad work pushed me and gave me a great sense of accomplishment. Will definitely be back to this location again the next time I am in Brooklyn!

  • The trainers are friendly and helpful!

  • Honestly, what's not to like about 9Round? I love the trainers, and it's great to walk in and know that even if not by name, you're known and recognized by them. The no class times works with my schedule, and even though it's nerve wracking to walk into an empty gym, you know you'll never be alone for long. I've been going so frequently, that 30 minutes flies by, and sometimes I feel so good that I feel like I could go a few more rounds. I'm so glad I joined, I can feel myself getting stronger, and I'm already seeing results! I would recommend this to anyone!

  • The flexible class schedule
    - June 26, 2018 by E.T.
  • I love 9Round! The owners and trainers are awesome and keep me coming back! The Brooklyn (Crown Heights) location is close and convenient for me so I have no excuse to show up at any time. Thanks all!!

  • Really great workout all the time, never the same workout either. Always switched up so you're never comfortable with the workout which is great!
    - June 16, 2018 by Santonia Joell
  • Great quick workout, great personal attention from trainers
    - June 15, 2018 by C.J.
  • This is a quick & intense workout - the trainers are amazing & make it fun while motivating you to push yourself.
    - June 14, 2018 by Jacqueline Iannacone
  • The intensity, the trainers, the feeling of accomplishment!
    - June 08, 2018 by Steven Gayle
  • The fact that there are no class times but you still get a personal experience with a trainer is quite frankly a genius-level breakthrough for someone with a schedule like me. The work outs are trying but not back breaking, the trainers are informative and encouraging, and it just feels good to punch a heavy bag before going off to work.
    - June 07, 2018 by C.M.
  • Love the workouts and the staff are super engaging!! Awesome experience and workout!
    - June 07, 2018 by M.C.
  • Every week there is a different workout to look forward to..
    - June 05, 2018 by I.F.
  • High intensity. Short. Over in 30 minutes. I can do it before work in the morning. I walk outta there knowing I worked out rather than putzing around a gym for an hour feeling like I didn't accomplish anything significant.
    - May 31, 2018 by D.S.
  • Class is high energy...go whenever you what no schedules....always fresh a new everyday a new challenge to push harder and get to your fitness goals.... my club is great! SEE YA there. CHERAE WARD CW/ BKLYNWARD NOSTRAND AVE, BKLYN

  • I love the entire concept of 9 rounds--it's quick, it's intense, and you leave feeling like a badass! Not only is AJ great overall, I've seen him welcome members and curious passerbyers like family each time. All of the trainers are bomb, and meet you where you are. Finally, this is a black-owned business in Crown Heights, and that to me may be the best part! Check them out, you won't be disappointed.

  • Small, communal feel of workout - everyone supports each other. Good workout, lots of energy.

  • No class times is perfect for my life
    - May 23, 2018 by Courtenay Daal
  • Having the trainers there to tell you what to do and how to do everything is really helpful, and the constant switching of stations keeps the workout from being boring.
    - May 16, 2018 by M.A.
  • Quick 30 minute all body workout. Great for fast pace life, everyone has 30 minutes to give
