I love this gym! A good friend invited me to go to 9Rounds with her on her one week free pass and had me hooked after the first class was over. I left feeling with my mood boosted and physically exhausted at the same time, if that makes sense! I have not trained that hard in a very long time and ONLY in 30 minuets but it was so much fun at the same time. The gym is cozy, clean but has a no nonsense atmosphere that you are there to work. Lauren is an awesome trainer who knows her stuff and she is definitely what I need to challenge my body out of its comfort zone. However, the trainers work with all fitness levels and will modify curcuits to fit your needs. Why 9Round is the place for me: I was a long time Fit4mom/Stroller Strides member when my now 5 year-old was a little tot and it worked in those short years for fitting in a good fitness routine with child in tow. Then Kindergarten hits and it was hard transitioning to find something that would get me my natural mood boost and fit my different schedule, especially with so many different choices of fitness centers in San Diego, it is nice to have finally found my fitness niche for this new phase in my life. There are no class times, so you show up and start your 1st round and have the bonus of a trainer to show you correct kickboxing techniques etc. Before you know it, 9 rounds, 3 minutes per round are done and you can go about your day! So... If you are not a yogi, not into Barr, Pilates or need a change from those large corporate gym clubs ( 24 Hour Fitness I am talking about you) please check out 9Round you will be pleasantly surprised.

I've had my 13 year old daughter going since January 31st and she loves it! There are some really good trainers that are high energy, encouraging, friendly, and most of all, patient We! We have some favorites like Fred, Brandon, and Courtney! They are attentive and know how to make for a fun environment! If you don't like all that, there's one trainer who we've had at the Friars location that is very bland and not very social at all and we prefer not to go when she's there lol. Just being honest! Anyway, my daughter loves that her workouts are different every time and she looks forward to going more and more. Our favorite trainers have taken the time to show her different forms to get better at different punches and kicks. We love 9round and this was the best decision we could have made for my daughter's fitness journey. The owner was very responsive when I first reached out to him on Yelp. There's a great combination of people that attend also with all different fitness levels! Everyone should feel comfortable being there! But like I said, you might wanna excuse one trainer because she kind of acts like you're not even there lol, but you'll figure out which trainers you prefer on your own. It's worth a try because it's only 30 minutes!

This place is AMAZING!! I am so happy I joined. I was previously with a big box gym and went in everyday like a deer in headlights not knowing which machines to do when or how much and left feeling like I didn’t get the workout I should of. Plus they charge you to have any instructions from a trainer. I LOVE here at 9round how the trainers walk you through each round and what to do. They not only push you to finish but cheer you on as well! All the trainers I have met are WONDERFUL!! I leave every workout dripping in sweat, tired, with more confidence that I did it, I am getting to my goals and stronger with every round! Thank you 9Round!!

This place has changed my life and it all starts with the trainers. They welcome all skill levels and get to know you and your personal goals. They remember where you’re at on your journey and support/push you to whatever level you want to achieve. Special shout out to the trainers I train with the most (they are all amazing) Fred, Sara, Taurian and Laura. Another special shout out to the ones I don’t get to see as much, but have been just as inspiring, Courtney, Johnny, Lauren and Addy. If you are looking for an inclusive, non judging great workout, get your butt in here and check it out. 30 min with this crew can change your life like it has mine.

I love this gym!! I've been a member of 9Round Kearny Mesa since it's founding, and can proudly say they've converted me to a 9Rounder for life! I cannot say enough about how much I enjoy the experience. I'm in the best shape I've ever been in, and I had so much fun getting there! I love that the workouts change daily, I love that it's only 30 minutes, and most of all, I love how hard all the trainers work to make me sweat!! They've got some wicked pad drills! Phew!! On top of that, the gym is always clean, and there's always a smile waiting for me when I walk in. Nothing better than a great workout with great people!

1. It works. -9R workouts burn fat, transform your body, and builds real strength (mentally and physically). Results tell the truth. 2. It’s fast. -30 Minutes. You will be burning fat during, and long after a 9R session, but half an hour is all you need to get it done. Getting in amazing shape does not take up hours of my day, and I like that. 3. It’s really fun! -9R workouts change daily, so I’m forced to expand my thinking, and grow in my fitness levels. Every day I’ve had to do something that I have never done before in my life. It’s never boring, and the format keeps me excited about going in for a workout.

When I joined 9 Round I wasn’t sure what to expect, but 4 years later and I couldn’t ask for a better gym. The workouts are tough, but they are fun as well. It’s a friendly and welcoming environment, with positive and motivating trainers to help you push yourself in the best way. Fred is one of the best trainers there, and has helped me so much during my time as a member at the gym. His positive attitude always helps grind out those last couple burpees! 9Round has helped me grow physically and mentally, and I can’t recommend it enough to anyone looking for a fun workout and a new challenge.

Love everything about this place. A great place to get a fun, effective, quick but challenging workout that gives you plenty of cardio but also works on your kickboxing form. The trainers are fun, energetic and skilled and periodically pull you out of the rounds to offer some one-on-one training. The best thing about 9-Round is their schedule. Their open hours are generous and best of all, there's no class times. The 30-minute, fun, effective, no-schedule format, translates into a NO EXCUSES workout!!!

Lost 36lbs since coming here! Everyone's super nice and it's great for people self-concious about starting to work out. The community is fantastic! I come almost everyday after work and I just wish they were open on Sundays so I could come everyday of the week. I truly can't pick a favorite trainer among the roster of amazing people; Fred, Courtney, Johnny, Taurian, Sarah, Alex-- everyone is impeccable and welcoming. You will certainly meet your fitness goals coming here!

I absolutely love 9 round. I joined about a year ago and I love how short and effective the work outs are! I get my work out in in 30 minutes and then I can head to work or drop my kids off at school after. All of the trainers give you a great workout and they are all very motivating! I have gotten stronger and built more endurance since joining. I love that I can show up at any time and start working out. Thanks 9 round for getting me a killer muscular body!

UPDATE: one year later: Sara, Courtney, Fred, Jonny, Addie, Lauren, Laura, Taurian, Leah and Jenna are all the BEST!! I always leave having had a great workout and a great time with these trainers! I've been a member for about 3 years now and this the best workout not only for my fitness but it's also just really fun. All the trainers are excellent with their knowledge as well as great motivators. If you haven't tried this workout I highly recommend it !

Love the drop in style. (no class times). Workout is always challenging - I’ve been seeing results quickly. It really works the core strength - never felt stronger in my life! I appreciate all the trainers, especially one on one focus and help. And they are so fun and remember everyone. The heart rate monitor and pulse points system make me push myself. I know I would slack off without seeing that immediate feedback on the screen while I’m working out.

I love how much like a family every staff member makes it. I can get this workout at a few places but not the hospitality, here it is incredible. Nothing motivates me more than seeing my low heart rate jump up because I just did a kickass round with a physical trainer. They’re encouraging and tough on you. Also, seeing the calories climb as you push to do better than your last 30 minute session is challenging but rewarding.

9 round will get you right! I absolutely love working out here. The trainers are motivating and push you to give your all. S/o to the Butcher, Lagertha, and Headband! I love that there's no class times so I can pop in whenever and get my workout. Eveyday its a different workout so its not boring and repetitive. Ive been coming for a few months and I already see results so my happy!

9Rounds is a perfect full body workout for only 30 minutes. The trainers at Kearny Mesa are encouraging, motivating & extremely knowledgeable! This workout is perfect for somebody who has a packed busy schedule and feels like they don’t have time to add the gym to their schedule! You will be shocked at how much you can work your WHOLE body in 30 minutes. HIGHLY RECOMMEND!

9Round is one of the best workouts I've ever done!! 30 minutes and I'm drenched in sweat. The trainers at Kearny Mesa are awesome!! They are super attentive and focused on making sure you get the most out of your workout. The atmosphere is high energy and motivating. 30 minute killer workout, no class times, and a fun environment...you can't get better than that!!

This is definitely the best gym I’ve been too. I’m honestly not a gym person but the staff here is super friendly always motivating me and helping me learn the work outs. This is definitely like having your own personal trainer. I’m so happy I joined!! . Everyone has been super helpful and nice, they always make me feel welcome! Love it!

No class times is awesome! Trainers are knowledgeable and extremely friendly! They will help you work through injuries or if you are looking to target specific areas! Make sure to communicate any issues or concerns before starting. Great for beginners! Update: Amazing people, members and trainers! Everyone there makes the workouts fun!

I've been going for a little over a month and I love it! The trainers are amazing, the workouts are super fun, and you get a great workout in ~30 minutes. I used to go to cardio boxing classes at 24 Hour Fitness, but 9Round gives me more flexibility and is a lot more fun. Each workout is intense and rewarding. Definitely recommend it!

I love all the trainers. They bleach everything down after you use it. The gym is probably as cleaner than a hospital. I felt very safe. You are at least 12' from anyone else and only 5 people at a time can work out. Did I say work out, I meant having fun, it is so much fun you don't even realize you are working out.

Awesome trainers! The location is easy to find and right off the freeway. The trainers are motivating throughout the whole workout and very friendly. I love the easiness of just showing up and doing a quick hard workout for the day. I always leave like I worked out for two hours and it was a quick 30min!

Excellent workout! Even better the flexible schedule. All trainers are fun and motivating, but Taurian was by far the best. He's experienced in all forms of martial arts and knows how/when to push you. I accredit my weight loss and overall enjoyment at 9Round to Taurian. Highly recommend this workout!!

This gym is incredible! The trainers are A+ and the 30-minute workouts are quick and effective -- perfect for anyone with a busy schedule! Parking can be a pain sometimes given the location, but that's the only, very minor drawback. Overall, I 100 percent recommend this place for getting your sweat on!

This place is awesome. Great trainers. Great equipment. The trainers are very knowledgeable and help with everything from technique to pushing you to do your best. The work outs change daily in great ways. You leave feeling like you really got your money’s worth. Shout out to Torian and Sarah.

9round is one of the many best decisions I've ever made. I'm proud to call 9round a second home. All the amazing trainers and all of the killer workouts are definitely worth 30 minutes of my day. I've accomplished goals that I've never thought would be possible & I thank 9round for that!

Always so personable!!! The cleanest gym I have ever been a member of. I have been a member for 3 years and I have always enjoyed punching it out and decompressing after work here!!! I have to say never fails that GMO delivers a great workout each time!!! We will miss you!!!

The trainers make it such a delight to workout. The level of engagement and encouragement is there and it helps me to stay motivated and wanting to come back daily. Also, every day the workout changes, gives me the variety I need so I don't get bored and stop going.

It's a 30 minute workout...who doesn't have 30 minutes? Plus all of the trainers are amazing. I feel welcome and like I have a home away from home. Only I'm working out in this home! I couldn't ask for a better experience and for a better environment.

The trainers are not only knowledgeable, but friendly, encouraging and so much fun! I always feel welcome and comfortable, even on my less energetic days. It’s more than a workout, its a fun way to get healthy and feel like you’re apart of a family.

9round is my favorite place to workout!!! I leave sweating and dead every single time and I’ve seen such huge improvements in my health since joining! Sara, Fred, and Addie are my favorite trainers and KILLLL me every single time …

It's a challenging but fun workout. Im not normally a big sweater, but these workouts leave me pretty soaked. The trainers are friendly and welcoming, but make you work. The other gym members are encouraging with one another. I really liked

I love the pre-planned, short yet effective, fun, and intense workouts. Trainers are awesome too! It makes me actually want to go and look forward to going to the gym. I used to hate the gym, but not anymore! No gymtimidation here either.

I've looked for a gym/exercise routine for a long time and hadn't really enjoyed working out until coming to 9Rounds. The exercises are always changing and rotated out so it doesn't get boring. The trainers have all been very helpful,

Love working out at 9Round. Only way to get a super sweat session in only 30 minutes. Routine always changes and the trainers are great. Special shout out to Johnny "Headband" for always pushing me to meet my goals.

I've never seen results so quick and have never stick with a workout routine as long as I have with 9round. Sunday's are the worst because I have to wait til Monday to get my workout in again.

Love the variety of the workouts and the fact that the trainers are actively involved and offer up alternatives when we need it. Plus, no class schedule means I can go when it works for me.

Today was my daughters first day trying kickboxing. Brandon was her trainer. He made her feel very comfortable ,everybody is so nice. My daughter loved her first day 30 minute workout.

Each time I workout I am never disappointed. The excellent 9Round crew make for a positive experience. Together with the determined 9Round members, it is an awesome gym. Thank you!

9Round Kearny Mesa has the best trainers! They all have positive energy and help push you through your workouts. Also no class times helps me to fit my workouts into my schedule.

The trainers at the Kearney Mesa location as so involved in your workout and encourage you to do your best. 9Round is such a great workout and it's only 30 minutes of your day!

Great work out! For all body types and fitness levels. Depending on your goals, this gym offers a mental and physical workout, leaving you feeling great after only 30 minutes.

The trainers here are helpful and motivating! I like that the exercises change every day and that workouts can be done in 30 minutes. I enjoy it much more than a normal gym.

I love 9round so much! The trainers are all awesome and the workouts are fun, I look forward to working out now instead of dreading getting up to do it all thanks to 9round

Great exercises and equipment, cool staff. Leah and Sarah keep everyone on track and know exactly when to step in to provide explanations of the workouts.

Hands down the greatest gym I have ever joined! The staff the atmosphere and the clients make this gym more like a family! Best decision I ever made!!!!

I love this gym! I have bad knees and I am still able to get a killer workout! The trainers are awesome and so helpful. Love that it's only 30 minutes!

Amazing location with even better staff! The trainer named Anna was very attentive and helpful. Great environment to workout and achieve your goals!

The perfect family environment. Everyone cheers everyone else on to be better and we root for success. Couldn’t ask for a better place to workout.

Shout out to this gym. Thank you always for the motivation and encouragement. I enjoy the changing workouts and learning from the trainers.

Love this gym!! It’s quick, everyone is so friendly and it’s really fun. Sara is so helpful and always makes sure I get the best workout!

Best full body workout you can get in 30 minutes! Love the variety and trainers are just amazing! Butt kicking workout every time .

I worked out here while visiting my daughter. Taurian is absolutely fantastic and I would highly recommend this location. Loved it!

They are encouraging and it feels like a family there. It is an amazing workout! The great part is, you WANT to keep coming back.

I absolutely love 9Round Kearny Mesa! The staff is the reason I’m back! They keep you motivated and the environment is so fun!
