I'm a man of regimen. F45 keeps me on track and in shape. The coaches are energetic and helpful. The classes are perfect for folks of all fitness levels. I myself am a middle aged man with the personal style of a K-Pop star, so this place perfectly fits my vibe. My fave coaches are Amber and Inna. Great music, great workouts, great gym. read more

Exceptional community, ownership, and coaching I usually don't write reviews, but when someone truly goes above and beyond, I feel it's important to acknowledge it. I recently wanted to bring a friend to her first Saturday workout at F45 Costa Mesa. I thought I had successfully booked us both, but later realized I was 5th on the waitlist and she was 3rd. She had a class pass but wasn't able to book on her own. Coach/Owner Bobby stepped in immediately and worked with me to make it happen. What really stood out was his communication and care. Coach Bobby kept me updated throughout the process, even replying to my email late at night with status updates. He never once mentioned fees or made it feel transactional--his goal was simply to get us both into class so we could work out together for the first time. And thanks to him, we did. It meant a lot to feel so valued as a member. Afterward, I reached out to thank him and offered to pay for the class, but he didn't charge me. Most importantly, my friend and I had an amazing time working out together. Beyond that experience, the coaching at F45 Costa Mesa is outstanding. Coach Bobby and all the coaches are attentive, supportive, and they challenge you because they know what you're capable of. One day, during class, I wasn't able to perform a jumping movement with weights due to back issues. After class, Coach Bobby took the time to check in with me personally, asked questions, and offered mobility and strengthening tips to help support my back and improve my performance safely. That level of genuine care, professionalism, and community is rare. F45 Costa Mesa isn't just a gym--it's a place where the coaches truly invest in you. I'm grateful to be a member here and highly recommend it to anyone looking for a supportive and challenging fitness community. read more

What can I say about F45 Costa Mesa?! I absolutely love everything about this gym. From the moment you walk in, you feel welcomed and supported.

I've always wanted to try a HIIT class, and it was definitely intense! Bobby and his buddy made my friend and me feel so welcome and made the class a lot of fun. They constantly checked in, made sure we knew what we were doing, and kept the energy up. We were exhausted by the end, but it felt so rewarding once it was over. read more

F45 has been a complete game changer for me! I've been coming here since August 2023, after I had my 2nd baby, and I can honestly say it has transformed my life. The biggest win for me is how close it is -- less than 5 minutes from my house -- which means I can hit the 5 AM class and be back home before 6 AM. As a busy mom, that schedule is everything. The workouts are challenging but quick, and the trainers are incredibly helpful, motivating, and always welcoming. They truly make you feel supported from the moment you walk in. I'm stronger, healthier, and more consistent than I've ever been. If you're looking for a place that pushes you, encourages you, and fits into real-life routines, this is it.

F45 has been part of my fitness journey for about 2 years when I stepped into the Costa Mesa doors and was warmly greeted and welcomed by the owner Bobby and coaches Emily, Amber and Justin.

Over the years my outlook changed and form improved, resulting in increased muscle mass and decreased body fat. Whether you are starting off or looking for a change or community, highly recommend F45 in Costa Mesa. There's an unmatched vibe the coaches and community bring. read more

I started working out at 45 Costa Mesa two months ago and fell in love with it almost immediately. The HIIT workouts are incredibly effective, well-structured, and never boring. Every session left me feeling accomplished and energized. What really sets this place apart, though, is the people. The coaches are motivating, knowledgeable, and genuinely care about your form and progress. The staff and members are so welcoming--it truly feels like a supportive family. I always looked forward to walking in because of the positive and encouraging environment. My reason for leaving is purely logistical: my schedule changed and, despite trying my best to make it work, I could no longer attend consistently. It was a tough decision because I value this studio so much. If you're looking for a fitness community that will challenge you, cheer you on, and make you feel like you belong, 45 Costa Mesa is the place. I'm so grateful for the time I had here and would recommend it to anyone without hesitation. Thank you to the entire team for creating such an amazing experience! read more

Let's go! They usually have some kind of deal where you can try it out for a week free. I went to a few CrossFit classes before this and found it a little bit intimidating. At F45 they have video screens that show you each move and make it simple. The coaches are really friendly and the owner Bobby is so supportive. The people who go here are a blast to workout with. I am going on 2 years at the time of writing this. It has been transformative and so good for my mental health. Come work out with me - I'm here 5 days a week pushing myself. read more

I've attended F45 studios in several cities, this was a pretty good gym. The equipment and surfaces were clean, music was loud enough. The coach demonstrated each movement and the rotation well. There was not a lot coaching during the workout, but she did count down the timing. I prefer having a coach give feedback, which is why I attend a class vs doing my own solo workout. read more

I started working out at F45 in Costa Mesa after a year of contemplating if I should do it because of the cost and because I was afraid/worried I wouldn't be able to follow the class. I was worried for nothing. The coaches and members were friendly and I felt welcomed. Every penny is worth it. If you've never done F45, just do it. The coaches will help you modify as needed and they'll walk you through the day's workout. It's normal to be confused for the first few weeks as I was, but your partner and coaches will help guide you. It may feel intimidating in the beginning but with consistency you'll build confidence. The coaches and the members at this studio are the best! Bobby and his team are caring and knowledgeable so don't be afraid to ask questions and make sure to tell them of any injuries! I highly recommend F45 Costa Mesa Square if you are looking to start your workout journey in a class setting. They also offer Hyrox training, which is a huge help for those looking to do a Hyrox race. read more

I'm not usually one to gush about a workout, but F45 Costa Mesa deserves it. This place is different. From the moment you walk in, the energy is contagious. The staff? Top-tier. Amber, Justin, Emily, Bobby and others a not just trainers--they're motivators, cheerleaders, and sometimes the kick-in-the-butt you didn't know you needed. What really stands out is the support and camaraderie. It feels like you're training with friends who actually want you to win. Whether you're lifting heavier, pushing through cardio, or gasping on the floor post-set, everyone's right there with you. No egos--just positive vibes and real people chasing results. And the results? Let's talk about that. I've noticed real changes--physically, mentally, emotionally. Body fat has dropped 4% in just a couple months. My physique has tightened up, my energy is through the roof, and my confidence? Yeah, it's back. There's something powerful about showing up every day, giving it your all, and knowing you're surrounded by people doing the same. If you're in Costa Mesa and looking for a place to level up--not just in fitness, but in life--F45 is it. read more

The owner, Bobby is very involved in the gym. He makes sure all of his clients feel comfortable and welcomed. I would 100% recommend this gym to anyone. read more

Great vibes on a Saturday morning from the staff and the class. Everyone seemed friendly. The instructors went around the room and tried to talk to everyone and coach them during the workout. I received lots of form correction and direction on an injury. Appreciated the extra help! The classes are usually 45mins long except for the weekends when it's an hour. Parking available right outside. read more

I love my F45 studio. I am currently doing the 45 day challenge and it has helped me focus, make small but impactful changes, and challenge myself. I highly recommend! read more

F45 Costa Mesa has been a great experience for me. The workouts are for everyone - you'll be challenged but no worries if you're a beginner! The exercises are demoed on the screen the whole time so it's simple to follow. The coaches are encouraging and welcoming! Shout out to Coach Bobby. He's kind and has great energy. It's a gym that anyone can thrive in. You just got to show up and be consistent ;) read more

Had to stop and give this place the review it deserves. It's not just because it's a great gym, it's also because of the interaction I've had with ALL the staff. I first starting going because my friend was a member and I wanted to join her. I was new to this type of workout, and it was a little intimidating walking in, but the staff was so friendly. They were more than happy to help me with my form (both during the exercise and if I had a question after class) and suggest modifications. I had a great experience with every trainer I came across. I bought a package and honestly had so much fun, I left feeling like a badass every time. Unfortunately I re-tore my meniscus (unrelated), and will have to give up a lot of these exercises while I try to recover without surgery. Bobby was so understanding. He refunded me for the classes I can't take anymore and shared his own story with meniscus issues. This place actually cares about its members and the staff seem to really like the job. Even though I won't be back anytime soon because of injury, I will happily recommend it to anyone looking for a fun home gym. read more

I've been to a few F45 locations and what sets this location apart from the others is the owner. Bobby is super welcoming and genuine which is comforting when you're coming to a new environment. (I never really saw the owners at the other locations). Feels like he really appreciates when you show up for your workouts. The trainers here are very friendly and observant. They're always giving pointers on how to get the best out of your workout (never really got much input at the other locations--they just let me do whatever). Parking is great! Compared to the other locations this one has nicer/updated equipment and has functional racks to train with as well! read more

This is such a fun gym and great community. The trainers are all really knowledgeable and helpful with correcting your form. It's small classes so you get lots of personal attention. All the other members are really welcoming and it's fun to work out in a group setting. Workouts are hard, but can be tailored to whatever level you're at. I highly recommend! read more

F45 has been so amazing with getting me back into an active and healthy lifestyle. The group classes make it a fun and supportive environment. Amber has been so motivating and helpful with my success in the gym. read more

Working out is one of my least favorite things to do. My wife signed me up and insisted that I try it out. I only planned on going twice a week or so, but after a week of classes I was hooked and started going every day I was free. It's been a year and a half and I go 3-4 times a week. Bobby is an incredible trainer who brings out the best in people and is always positive and encouraging. Couldn't recommend it enough. read more

Bobby and the whole f45 team at Costa Mesa Square are just the best! It's always a positive and uplifting environment in class, and I love that the coaches push me to be my strongest self! I always leave feeling like I got in an amazing workout. Would 1000% recommend! read more

This gym has such a great community and I always enjoy my time here. I've done 3 challenges now and I originally signed up just to get involved and meet new people. I have continued to do each challenge because I've had such a great experience with the coaches and all the other members. The coaches did a good job at holding me accountable, pushing me and providing me with helpful knowledge. Each challenge, I have taken something away from it and continue to apply it to my everyday life! read more

I moved to Orange County in July of this year. I had previously been going to an F45 gym back in Denver so I decided to try out local F45 gyms in the area as Passport visits. While this isn't the closest gym to me, I consider it worth the short trip on the 405 at rush hour. The owner, Bobby Ishii, is the one who sold me on this location. The workouts are the same no matter where I go, but this is the only gym with Bobby at the helm so this is where I'll stay! read more

It's been almost a year since I've been attending the studio and I can confidently say it's been an amazing experience this far. The trainers like Ashley and Dave along with Bobby genuinely care about you and your fitness goals and are very helpful with their knowledge. 100% recommend this studio :) read more

My husband and I tried F45 after our last gym closed and we are glad to now be members. The workouts are challenging and Bobby and the crew of trainers are all very helpful and provide tips and suggestions especially when dealing with soreness or injuries. The 45 day challenge is a fun way to get on track learn regarding proper nutrition and incorporating workouts along with optional fun/social events that allow you to get to know other members. Other places make you feel like a number, not the case at F45. read more

I did a trial at F45 in Costa Mesa for a week. I felt great and stronger every day. I was a newbie to weights, and Bobby was so knowledgeable about posture for each position.

All the trainers, and the studio owner Bobby, at this location are amazing, friendly, supportive and give you personalized treatment.

Bobby and team have created an amazing F45 studio with unparalleled culture, workouts, and a product that works. During the time that I was able to work out at F45 Costa Mesa, Bobby, the studio's owner immediately made me feel at home with the crew, and the trainers (Omar, Matt, Joey) were able to provide attentive support during workouts (providing tips on form correction to prevent injury) while creating a fun, calorie-slashing atmosphere!

Love my workouts at F45! Bobby and his staff are the best- super friendly, motivating, and great energy!

I started coming to F45 Costa Mesa square through classpass about 4 months ago. From the first class I could tell the workouts were exactly what I was looking for, and this is a special community. The coaches do a great job of getting to know everyone and helping with anyone with needs for modifications.
