I highly recommend F45 Costa Mesa Square. This gym is inclusive for all fitness levels. I especially like the F45 45 day challenges. I've completed a couple challenges now and each one is different and motivating. You participate on a team with a coach to focus on your fitness goals. The teams are encouraging and motivate you to create sustainable habits. read more

I joined about 6 months ago and it was by far the best decision I made all year! From day one I've felt welcome by both staff and fellow gym peeps. All of the coaches are knowledgeable and bring a fun energy that keeps you going during the workouts and excited to come back for the next! Best of all, you will see noticeable results! Huge thank you to Bobby, Alex, Amber, Emily, Joey and Matt who are all amazing coaches and make sure form is on point.l and keep me moving!!! read more

I have been attending F45 and this studio for a little over six weeks now and it has been amazing. The culture being created at this studio among the coaches and athletes is incredible. Everyone supports each other in a positive way every workout. Having a 5AM class is excellent for busy schedules and getting in the workout before the day gets started. I enjoy group exercises because I don't like having to put together workouts. F45 has the variety that I really enjoy. It allows me to push myself harder depending on the workout. I enjoy cardio days because they come naturally and the strength days are a nice change of pace and help breakup the workouts during the week. I want to work on strength so I am glad we have those days and that the coaches push up to lift heavier within our capabilities. read more

Can't say enough good things about Costa Mesa square and the coaches! I moved from Tustin F45 where I met Bobby and joined his new location here in Costa Mesa. It's been wonderful to see the gym grow with new members and trainers. If you are looking for a gym community that helps one another grow this is the place for you! read more

Let's start by saying this place has a very inclusive feel. People are nice and it's not pretentious. The owner Bobby is great! He cares about his patrons and is available for any questions or concerns about the program. I haven't worked out seriously in over a year. I had major abdominal surgery 3 months back and felt very nervous about getting back into it. The owner Bobby reaches out to new members and has an open dialogue about any issues or nervousness in my case. I really liked that! Im very new to this program but I'm excited about getting stronger and feeling in more control of my body again . F45 is a great total body approach and can be modified based off your current abilities. The coaches check your form and want to see you progress safely and successfully. I love that the same class runs all day so I'm not trying to rush to get to a specific class at a certain time. Makes life easier. Check it out! If you want a community to get stronger with and challenge yourself to be better, this is the perfect place! read more

Coach Bobby and his team of trainers are beyond exceptional. They've curated a welcoming atmosphere for the newcomer to the advanced athlete. The vibes of this tribe of warriors is off the charts. Highly recommend taking some classes here to elevate and go beyond the self imposed limitations. https://www.instagram.com/reel/CpnbeTKgc9G/?igshid=YmMyMTA2M2Y= read more

I've been to quite a few F45 clubs and I have to say this is my favorite! Bobby and Alex makes the class engaging and fun. You can go at your own speed but they'll remember to ask if you want more challenge and then recommend the appropriate steps. I almost didn't write this review bc I didn't want more people knowing about this place. But honestly, you can't beat a 45 minute in and out workout! Goes by super quick. And the bonus is that I've lost weight and gained lean muscle mass! read more

The F45 in Costa Mesa Square changed my life. I have been to different F45 in various locations and I always compare it to this one. None of the other gyms can top this one (in my opinion). Bobby (the owner) is my hero. Him and his team really cares about you as a whole person, in terms of succeeding in all areas of your life and not just fitness. The last time I was in the best shape of my life was 14 years ago and I never thought I could attain that again. This gym helped me reached that goal. This place is more than a gym for me, it feels like a second home. I love the community feel, the support of everyone that's trying to do their best to reach their goals and most importantly, the trainers that push you beyond your limits that you thought was impossible but possible with their help and encouragement. I can't thank this gym enough for everything that they have done for me and I hope that everyone that reads this can give it a try and see it for themselves. read more

Just started taking classes here and am super happy. The place is clean, and everyone is nice and welcoming. Amber and Emily have great energy and make the classes engaging and positive. The workouts are a blast and have great variety. Met the owner, super cool guy and he cut me a good deal so overall I'm happy to be a part of this gym! read more

This is the 3rd F45 location I've been to and the best one by far!

Overall great environment for a fun & exciting workout that will help to achieve your fitness goals at the same time! read more

I joined F45 Costa Mesa after my bootcamp-style gym closed abruptly, and we were all scrambling to find a new place. We had loved our old gym, the trainers, the workouts and the community, so the bar was high. Where would we go? Two of the gals from the old gym started going to F45 Costa Mesa and could not stop raving about it. I knew they were very picky about their workouts, so I of course immediately signed up for my free week. Bobby, the owner, immediately texted me a warm welcome and asked about my fitness goals and journey, and any concerns I had about F45. I said I was worried that I wasn't fit enough to go the full 45 minutes (the old gym format was 30). He reassured me that I could go at my own pace and modify as needed. I started in Oct. 2023, did my first workout, and was absolutely hooked. Not just with the workouts, but with everything: the spotless gym, the variety of formats, and, most of all, the fantastic coaches! Just when I think I can't do another rep, they come over and encourage me. It works every time. At 54, I am the strongest I have ever been in my life. I am grateful to Bobby and his excellent team for helping me achieve this. Onward and stronger! read more

This was the best workout I struggle with form and struggle with pushing myself but here they really help motivate you to push through. Had so much fun doing this! shoutout to Britt and Bobby they really made it the best most comfortable experience. Def coming back read more

I have trained at several F45 locations but nothing compares to F45 Costa Mesa. The trainers are knowledgeable, attentive and caring. When working out you are pushed to your potential and uplifted just for showing up if you aren't feeling your best. The studio itself is always clean and fully stocked with towels and shower necessities. The Owner Bobby cares a great deal for his clients and trainers and it shows. Thank you for growing such an amazing community! read more

I'm not normally gym-goer, but I was invited to give F45 a try while visiting my sister and was pleasantly surprised by the experience. The gym primary focuses on 45 min classes with multiple workout stations that changes day to day. I found it a lot different than what I expected from a typical gym. These sessions are led by multiple instructors/trainers as you rotate through the stations. I found the experience well organized and great for a first timer like me me who would otherwise not know what to do. Shoutout to Bobby for making my first experience great! If given the chance would go again! read more

Where do I start!? I've been working out at group fitness studios across OC for years, F45 is absolutely outshining the competition. The workouts are creative and always changing. The trainers encourage you and challenge you during class. The camaraderie is super fun, especially for people who like working out before and after work! The classes are powerful enough to burn 500+ calories and yet short enough to fit in with a busy work schedule. I was seeing noticeable results in my muscle tone and strength after a few months. Thank you F45!!! read more

Amazing gym! Love the atmosphere, people and trainers. They are so good, you don't mind waking up on a holiday to go work out.

Bobby and his staff are amazing. His gym is very clean and organized. I would highly recommend anyone at any fitness level to give this place a try. read more

This studio was my first introduction to F45 when it grand opened back in August of 22 and I've been coming multiple times a week since. Nothing but positive things to say about Bobby and the entire team here they are all awesome! I used to do class pass and checked out a bunch of other local gyms that I enjoyed. This is my first time buying an unlimited membership to just one place because I feel like it really does cover all the bases. 10/10 would recommend. read more

If you want to improve your health, performance, body composition & overall well-being, check out the F45 Training at Costa Mesa Square. The coaches are phenomenal! The trainers are attentive, encouraging & they provide guidance on proper form to achieve max results. I've definitely seen results, and feel physically & mentally stronger. The coaches & trainers have helped me build many good habits through the 7-8 week challenges. Classes are challenging enough to burn 500+ calories, but short enough to fit a busy schedule. Equipment, environment & bathrooms are clean. The studio has a shower & offers hand towels for workouts. What really makes the studio at Costa Mesa Square unique are the owner, trainers & people!

Posting an update to reiterate how fantastic Bobby and the F45 team are. I was able to exercise through pregnancy and postpartum (approved by my doctor), and all the coaches welcomed me with open arms, showed me modifications, and checked in on me; they never made me feel out of place or like I was a burden. This F45 team will meet you where you are on your fitness journey and cheer you on along the way. I strongly recommend checking out F45 Costa Mesa Square! read more

When not at my regular F45 I always try to visit other F45's when I travel for work. To date I have been to 7 or 8 F45's in the Western States, and this location in Costa Mesa has been the best one yet. Great setup, great lighting, nice bathrooms, and great instructors. I've been coming to F45 for over two years and I would highly recommend it for anyone looking to mix up what they are currently doing or if you are new to working out. F45 truly is for individuals of all skill levels. You will love it and hate it at the same time, but you will see and feel the changes. 45 minute classes, cardio some days, strength other days and hybrid workouts as well. And for a little extra, Saturdays are hour long classes. It's not CrossFit. it's better in my opinion. Go see Bobby and his team and have a blast. read more

I have been coming to this F45 location for two years now. My old studio closed with short notice and I was hesitant signing up at a new F45 location. I decided to try it out for a week and see how I felt. I am so thankful for Bobby & all the coaches at this F45 location. I have felt welcomed since day one and on days I don't feel like working out, Bobby & the coaches motivate me as soon as I walk in. They have helped with my form, given me targets to hit, helped with recovery, host social gatherings were I have gained so many wonderful friendships. If you're thinking about joining, just do it, you won't regret it read more

I can't say enough about the professionalism of this business and it's staff. I've been coming now for about 3-4 months and am absolutely hooked! They make sure you are comfortable with the exercises and are always assisting you in proper technique for no injuries and maximum results.

I will be back when in town again! read more

I've been going to F45 since it opened in August and I can't believe I still like it! The classes are only 45 mins so it goes by pretty quickly and change daily (cardio/ lift/ hybrid). The coaches are knowledgeable and attentive. They will correct your form and challenge you to do better. Fellow members are friendly and encouraging. There's also towel service and plenty of parking. Not sure if I've lost any body fat (lol) but I feel so much stronger. Thank you Bobby and team! read more

Where do I even start. The F45 CM Square team are unlike any other. Bobby & all the trainers (Ashley, Katie, Gracen) are so genuine and welcoming and know so much about training, recovery, and overall physical health. I suffered a back injury (herniated disc) last year from going to another gym where I was basically just a number and I was a little hesitant before starting F45. Fast forward to several months later and I am feeling stronger than ever! The team really focuses on form and pushing yourself but not overdoing it to the point of injury. They are always walking around and making minor adjustments to form while also cheering you on! Lastly, you also are not just a number here. They know everyone by name and it's a little family that I'm so happy to be a part of. read more

I've been doing F45 for a little over 2 years and switched from another studio to this one. I couldn't be more pleased with the services, attentive trainers and awesome community at F45CM square. What makes this studio so special is that the trainers actually pay attention to you and give you challenges at each exercise, remind you to engage certain muscles, push you and encourage you. Bobby, the owner, is the best at his craft and the other trainers Gracen, Ashley and Katie are also great! Another plus about this studio is that after every single class, they offer light stretching and foam rolling, which is essential for recovery. I've never seen any other F45 offer this amenity. They also offer towels and there's plenty of parking. Highly recommend F45 Costa Mesa square! read more
