  • The all-around energy you get from this workout. From the trainers to the workouts each round to the amount of pad drills, 9Round is an incredible workout. Not to mention the high standard set at 9Round Kearny Mesa, it’s unparalled by any other 9Round gym I’ve experienced. Hands down, greatest workout experience and gym I’ve been lucky to be a member of. Anyone who hasn’t given this place a try is missing out big time!

    Brandon "The Bossman" Danieli
    I was a 9Round member and decided I couldn't get enough of this workout, so my wife Missy and I decided to open our own gym! I have always loved fitness. I played a year of college football and had always lifted weights until I found 9Round. The resistance from hitting the bags combined with the cardio and the convenience of the 30 minute workout has been a life changer! I'm getting better results compared to my prior workout routine and it only takes 30 minutes. At our gym, Missy and I only hire members for trainer positions. We have found this gives our members the best experience. We are so happy to have found such a great group of trainers that help keep you sweating and smiling! Brandon

    I have been in the US Navy as a Nuclear Engineer for 15 years now. I have traveled the world and continue to do so today. I joined 9round because I could never seem to add cardio to my normal workout routine. I decided to walk into this kickboxing gym and talk to Brandon, and was intrigued as soon as I walked in. I have been a member since Aug 2016 and have seen big improvements in both technique and form. The workouts are fun, convenient, and always different. As soon as I completed my first workout, I knew that this would be something that I would love to teach as well. In October 2017 I completed 9Round's Master Trainer Bootcamp!

    I am a proud Navy spouse and momma of an extremely energetic 7-year-old! After moving from Washington to New York to Japan to California, I have finally gotten myself back in college. I’m getting my degree in the Health Information Technology program, and can’t wait to finish and get started the medical field. With the busy, dynamic life we lead, I was very excited to discover a workout that fit into my schedule! Only 30 minutes, at any time of the day? Can’t beat that! After months of being a member and getting to know the fantastic team that works here at 9Round, I was ready to jump in and give other members a great workout! I’m excited me meet all of you and get you sweating!

    Laura "The Crusher" Crisp
    I joined 9Round Kearny Mesa after coming home from a deployment to Afghanistan as a Navy Nurse. I needed a challenging workout that incorporates strength and cardio, is flexible with my nursing schedule, and engaging enough to keep me motivated and consistently working out. My roommate suggested we try 9Round, and I’ve been hooked ever since! I’ve never sweat so much after a 30-minute workout in my life. I love having the opportunity to work out with other people and a trainer, but no class times! I became a trainer when I transitioned into the Navy Reserves in June. I’m excited to give you a killer work out and to show you why 9Round Kearny Mesa is the best gym in San Diego!

    Melinda "The Maniac" Jernigan
    I was not a big fan of gyms because I was never sure what to do with all the machines and equipment. I kept trying different group workout classes but never found one that made me want to join. I had two friends recommend me to try 9Round Fitness Kearny Mesa because they were members and they loved it. Since they offered the first class free I figured I had nothing to lose. After that first workout I thought How crazy it was that I was able to work so hard in just a 30 minute workout. I have been a 9Round member for a few months and I have enjoyed every workout. If I'm not at 9Round you can find me at the beach or park with my dog. I am excited to be a part of the 9Round Kearny Mesa family and look forward to meeting you!

    I'm a fan of lots of types of exercises, but 9Round stands out from them all! Not only is it efficient, highly active and different everyday, but it will be as challenging as you make it. I'm a graphic designer by trade, so after hours I'm sitting at a computer. All of the punching and kicking in this workout is some extremely fun stress relief! Come on in and workout with me!

    Maya "The Monsta" Zaken
    I have always been some sort of athlete growing up, whether it be volleyball, Raiders and Orienteering, ROTC in college, or swimming. Which means I don’t like working out by myself in regular gyms. I love having drills ready for me when I walk through the door and that is exactly what 9Round is about! I have traveled all over the country and have gone to 9Rounds in several different states, and Kearny Mesa takes it to the extreme! I always loved the energy from the trainers when I was a member and that they did so many pad drills with me. My favorite is getting to shin kick and roundhouse kick with the trainers. After a few months of working out, Brandon gave me the opportunity to become a trainer and I have loved every minute of it! So come in and punch and kick things with me!

    Jenni "J Wow" Marchisotto
    I first joined 9Round as a fun and convenient full-body workout. After playing competitive water polo for almost a decade I had trouble finding a workout that kept my interest. 9Round did the trick! The 9Round Kearny Mesa community is incredibly supportive and engaging. I am always happy to get to the gym. The workouts are tough but fun, and I always leave the gym tired (in a good way!). After being a member for over a year, I am excited to work as a trainer. I understand the workout experience from both sides and love to think of new and creative ways to work up a sweat! Give it a try and join the 9Round community!

    Missy "The Machine" Danieli
    I love to workout, am passionate about fitness, and nutrition. I tried multiple workouts and find it hard to stay interested, that is until I discovered 9Round! The workouts change daily, keeping me engaged and I have full access to personalized nutrition. Not to mention there are NO CLASS TIMES which fits perfectly into my crazy schedule! Can it get any better? I can't wait to share this passion with you!
