Member Reviews

  • I never had a gym membership so I wasn’t sure if i was willing to make that step. I can say I have never regretted the decision to join 9Round. Absolutely the best workout experience I have ever had! 9Round gives you a great workout in just 30 minutes with no class times. Because of the flexible hours and no class times, I am always able to find a time to work out that works for my schedule! I never thought I would enjoy working out 6 days a week, but with 9Round its possible! The workout never gets boring because there are new exercises everyday. The trainers are amazing! They are always present and make sure you are doing the exercises correctly. I love how they encourage me to always work hard. Working out at 9round has boosted my energy level and helped me to tone up. Thank you 9Round!

  • 9Round has been great for me! I am excited to go into the gym because the exercises are different each day. Each of the staff members encourages you to push yourself, and you get personal attention during every workout. The atmosphere is friendly and welcoming, and I would encourage anyone of any fitness level to try it out because everyone could benefit from this type of program.

  • I just moved to Fort Worth, and was in desperate need of a workout routine. I went in for my first FREE work-out and was hooked! I joined this gym a month ago and am already down 8lbs!!! I’m not in best shape by any means but Yvonne & James are great at cheering you on and helping with modifications so you can get the best work out possible. James will even pull out the gloves and make you work/sweat for every punch & kick! My work schedule is so hectic, it’s a relief to know I can come in at any time and get a solid workout in 30 minutes with a trainer! I am so happy I found 9Round in Keller – James and Yvonne really make the gym what it is! I can’t see myself going anywhere else!

  • I cannot say enough good things about 9Round and it's owners/trainers. I am employed full time with three very active kiddos whose sports/activities schedules are challenging so 30 minutes is about what I can spare in a day for a workout - James, Yvonne and Misty make sure I get the workout that I need in those 30 minutes. They push me and the other 9Rounders (in all shapes and sizes!) in the gym to do our personal best each time we are there. I love the challenges of the week and that the workouts are different each day. I have recommended 9Round to several friends and family and will continue to sing it's praises.

  • Love that I joined 9Round in Keller! The 30 minute "anytime" concept is perfect for those who have schedules that are busy and never the same. The workouts are different and challenging every time. James and Yvonne a so welcoming and encouraging...and give you the attention that makes you want to work harder for them. I feel stronger and have more energy and love that I'm losing weight and toning up. Love 9Round Keller!

  • I absolutely love 9Round. I've been going to 9Round for a month now and I have already gone down a pant size and I can see so much muscle definition. The workouts are challenging and so much fun. They change daily so you never get bored. I'm always looking forward to seeing what James and Yvonne have set up for the day. You get so much encouragement and attention during your workout that it makes you push harder. And they are super affordable. I love everything about this gym!
