Fitness & Gyms in Costa Mesa, CA

“The best place ever tbh. The people, the community, the workout, I'm obsessed. I love that they have so many different types of classes and I always leave feeling stronger. I love you MOXI3!”

“AIM Fitness is an awesome gym with a great atmosphere. Marla and Jake are both incredibly friendly, knowledgeable, and always willing to help. The gym is clean, well-maintained, and welcoming to everyone. Highly recommend AIM Fitness to anyone looking for a great place to work out!”

“As the name suggests this is a true Hyrox training facility. Expect a lot of running, rowing, ski erg, burpees, and all the other treats that keep the heart rate hammering. Some of the training takes place outdoors and it was HOT but I figure this will toughen me up even more. Matt took individual time with me to help me with my sled push form which I greatly appreciated. Everyone was very nice. I thought I would throw up several times so I can safely say the workout did was it was supposed to do 😂. I’ll be back!”

“This gym is great. Has been my go to now for about a year. Staff is super friendly.

Pros: Nice long hours, clean and relatively not crowed in the mornings

Cons: It's a little hard to get a shower scheduled”

“love this gym! everyone is there to improve themselves, super helpful and ton of knowledgeable people working out all the time, everyone that works there is nice, and the facility is 10/10 top notch equipment and cleanliness, they really care and its such a great gym!!!”

“I would like to share my experience for the services The Camp Transformation Center provides. This is a gym where you can leave your problems and stress behind and enter a world of laughter and enjoyment while doing your workout. This gym provides HIIT classes, each day of the week focusing on either upper body, lower body or full body. They also provide elite weight training with a smaller number of people. The place is always clean, neat and provide the necessary equipment to perform your exercises. The staff will always welcome you with a smile and positive vibes. I specifically would like to give a shout out to Luis, a trainer that came on board not long ago and has shown such commitment to provide the best motivation and extra push to his clients. The type of exercises included in his HIIT classes have been very unique with each being able to modify to low impact. I recommend you join! I personally have met my gains in just months!”

“Wow world class experience. If you’re anyone who is looking to improve mobility, posture, and core movements/drivers of physical health, Dale is your guy.

I can say this on the basis of working in this space professionally + personally for years and also having seen various physiatrists, physical therapists, massage therapists, personal trainers and sports specialists over the years: Dale is top notch.

Detailed, customized approach and you can see the effort that he puts in his work. 12 out of 10 and I’m not just saying that because he’s a nice guy (which he is lol, very personable).

I’d recommend him to anyone from the 40 yo weekend warrior needing help w back and hips, to the geriatric individual looking to improve their balance, to the high level athlete looking to optimize their performance. Dale is a beast.”

“The staff here are very cool and super nice. Everybody went out of their way to make sure I was taken care of. I would definitely recommend Muscle D Fitness to anyone that needs fitness equipment.”

“All the trainers are really nice and supportive it’s always a really rewarding and efficient 45 minute workout. I would recommend to anyone looking to join a new gym”

“My team and I recently had the opportunity to experience a class at The 12, and it was exceptional from start to finish.

The workout was thoughtful, effective, and accessible to all fitness levels, but what stood out most was the people. From the moment we walked through the door, we felt welcomed, encouraged, and supported.

After class, I asked each member of my team to describe how they felt in a single word. The responses were: empowered, motivated, hyped, confident, strong, grounded, and supported.

Those aren’t simply words that describe a workout. They describe a mindset, a lifestyle, and the kind of transformation people are searching for in their lives.

Brooke did a fantastic job leading the class, and our entire team left energized and inspired.

What Josh and his team have built goes far beyond fitness. They’ve created a community centered around growth, accountability, connection, and becoming a better version of yourself.

We’re grateful for the experience and look forward to continuing our journey with The 12 and embracing the lifestyle that makes this community so special.”

“i've been going to this gym for seven years and I love the classes. I love the vibe. It's great how the coaches will adjust the work out to meet your needs. I'm in my 50s so I really appreciate that cause there's many levels there. I decided to do some personal training and I'm really appreciating it because my coach Yaremy has really been guiding me to make sure I'm doing the right movements and I don't feel overwhelmed, so I feel very looked after and cared for and that's really kind of what I need at this stage in my life and it's been really great!!!”

“Paul has improved my surfing and overall mobility tremendously. He is a very dedicated and genuinely enjoyable coach to work with. His expertise is outstanding, and I can confidently say he’s done far more for me than many physical therapists ever did.

I came to him with a hip issue (FAI), and he tailored a program specifically for my needs. I saw results immediately. There’s no fluff with Paul—he goes straight to the science and to what actually works.

Surfing is such a niche sport, and you simply can’t rehab or improve with generic football/baseball/basketball-style programs. I learned quickly that your training needs to match the demands of surfing—and Paul is the one who truly understands that. He’s the coach for me!”

“Lo is the best coach. She corrects my form to ensure I get the most out of every movement. She’s encouraging, supportive and challenges me. Top tier instructor frfr!”

“I trained with Glayol Kashani from built by g for 6 months now, and she was able to get me interested in pursuing my weight loss journey again. I felt weight loss wasn’t in the cards for me, I had tried everything in the past and i seemed to keep gaining weight.She pushes me like no one else, every workout is way different than how I would train on my own and during our rest periods, she’d give me detailed nutrition feedback. I’ve lost almost 40 lbs with her guidance, I commute almost an hour to see her and she’s worth every minute of the drive.She’s very knowledgeable about the science behind exercises and tweaked the program for me as a caregiver and needed to be strong in different positions for my job. She added exercises to my workouts for my lower back pain, and helped me get stronger at my job. Before working with her, I wasn’t flexible or strong enough to hold and move another human being without getting hurt. After working with her, I can do so much more without pain.So next time you're at this facility, make sure to ask to coach with built by g. She’s the real deal.”

“Been going here for almost 6 years now. The coaching is unmatched here. You get experts in strength, speed, conditioning, muscle building, fat loss, athleticism, nutrition, recovery, you name it and it’s found within the walls and minds of this gym.
They have trained and coached 10s of professional athletes from strongman to football to world champion BJJ artists.
The gym has a vast amount of equipment and exactly what you need to make your goals.”

“I’ve been here for around 2 years and it’s the best gym in OC. I prefer it over equinox because equinox has too much fluff and nonsense. It takes like 10 minutes just to start working out from valet to locker room, etc. Infinite is straight to the point. Everyone here is super nice and serious about training. It has the best quality equipment. Aesthetically pleasing. And it has the wellness stuff if you’re into that.”

“This is my regular home gym - and I've been going here for seven years. I love the vibe, the way classes are set up, the personal connections you make with the coaches and classmates - there's a sense of order and kindness here that is welcoming. I'm a deeply athletic person and when I've needed to scale back for injury recovery, there's been personalized and attentive consideration of my individual needs within a group class format.”

“This place has an abundance of equipment. There are plenty of squat racks (6 to be exact), 5 benches to bench on, plenty of weights to choose from, various equipment for both lower body and upper body, and this place is very clean. Another topic that should be discussed is the limited times there are for this fitness center. I should advise all that the fitness center will only allow students who signed up for the specific classes that offer the gym. Let me repeat, this is a class, not a public gym. Times are setup, how a class should be. The coaches are there to help you if you need any assistance on how to work a specific body part. Overall: 9/10”

“Started going by to this gym and I really enjoy it. Classes are small and personalized. Tony makes sure you use proper form and makes sure you don't slack off. People at the gym are really friendly and enthusiastic about working out. This isn't your regular gym where you will go and then they forget about you! They really care about your commitment and fitness goals. If you're looking to get in shape I highly recommend this gym.”

“I drive allllll the way from Corona to spin at Grit 2-3x a month. The energy, the intensity is always the same. The choreography, although can be a little intimidating gets easier each time you go. No matter Your fitness level, your age.. You can take something away from Grit.. I wish I could go everyday but the 91 doesn't allow for that..”

“Two years in and I'm still hooked! The coaching is genuinely elite, the programming is smart, and the community is the real deal, competitive or just for fun. I came for a trial and this place has pushed me further than I thought possible. If you're considering it, just show up. You'll understand immediately.”

“I enjoy this place for quick workouts when I’m short on time & my kid LOVES it because of the swim classes. When she turns 10 she shall be able to work out with us as well. I’ve been to other YMCAS & This one definitely is the nicest looking because of the back bay view, I only wish they had basketball courts Available for use.”

“**disclaimer: may be difficult to find on your first trip here. Its on the basement 2 level.** I'm glad of the two 24 hour fitnesses which were so very close to one another, in this location, that this one is the one remaining. It has a pool, jacuzzi, sauna, & steam room. It has a decent amount of weight machines, some which could stand to be upgraded but for the most part machines appear to in good order. Timing is everything, but even when I've gone during rush hour I have been able to access machines with little to no wait time. But seeing as I want that to continue to be the case I would highly recommend looking elsewhere for your fitness needs haha.”

“Went to Chalk Performance CrossFit with my buddy Whitten and had a really solid workout. The whole vibe of the place was super good from the second we walked in. The community there was super sweet and kind, especially for it being my first visit. A bunch of people introduced themselves right away and made it feel way less intimidating. Our trainer Caitlin was awesome too. She was extremely sweet but made sure to push us the entire time, adding weight and keeping us moving at a good pace. It was that perfect balance of being supportive but not letting you coast through the workout. Also gotta shout out Jess, she was super sweet and made me feel even more welcomed. You can tell they have a real community there and it is not just about the workout, it is about the people too. Definitely a spot I would recommend if you are looking for a place that challenges you but also makes you feel like you are part of the crew from day one.”
