I've been going to 3D Fitness 4-5x/week for the past three years -- including all the way through…read moremy first pregnancy -- and it's easily one of the best decisions I've made. The workouts are strong, but that's not the differentiator. The community is. You see the same people consistently, and over time it becomes a tight, supportive group. It's rare to find a gym where you actually look forward to who's going to be there, not just what's programmed. Programming is thoughtful and well-balanced -- strength + high-intensity cardio -- and it never gets stale. Chris (owner/instructor) is especially good at reading people and pushing you just past where you think your limit is. You end up doing more than you expected, regularly. There's also real connection beyond the floor. They organize occasional events -- I recently did a cooking class with ~20 women from the gym -- and it adds another layer to the experience. I've always been active, but this is the first time in 20+ years I've been this consistent. That's not accidental -- it's because of the environment. If you want a place that will push you, keep you accountable, and make you want to show up, this is it.

I've been a member of 3D Fitness for 7 years now, and it continues to impress me every single day…read more What keeps me coming back is the incredible variety in the programming. I love walking into the gym not knowing what to expect, and being surprised by a new challenge each time. It keeps things fresh, fun, and far from boring--even after all these years! They've also added some new equipment, which has taken the workouts to another level--more dynamic, more engaging, and definitely more effective. The thought and creativity put into each class really show. This place isn't just a gym--it's a community and a source of daily motivation for both physical and mental health. Highly recommend to anyone looking for a fitness routine that keeps you on your toes.

Ark Fit has truly changed my life. As someone who has always felt insecure in gym environments and…read morestruggled with being consistent, I can say this is different. I've tried everything--from traditional gyms to ClassPass and CrossFit, until my sister introduced me to Ark Fit. The facility has all the equipment you could need, but what truly sets this place apart are the coaches + staff. They have created a warm, welcoming environment and built a supportive community. Open gym is always a vibe and kept so clean. The classes are as challenging as you want them to be, and coaches meet you where you're at. Every coach brings the same positive energy, understanding, and kindness to each class. Regardless of your fitness level, you'll never feel lost or left behind. If you're looking for a gym that combines expert coaching, an incredible community, and a truly welcoming atmosphere, Ark Fit is the place to be.

Finally started hitting the gym again and this was my second time visiting this location. Came here…read moreafter work with the work wife. The place looks and is fairly clean, it was crowded this evening on a Wednesday around 630pm but we did not have to wait for machines or benches. Free weight on the other hand were being boarded by multiple girls. Plenty of paper towel dispensers and spray bottles so some people are good at wiping down the equipment. Wished the staff was more attentive and present on the weight lifting floor to try rack the free weights and plates. Overall if you get one of their promotions it is not a bad gym.

I have been a member of EōS gym in Corona since it opened. I work out here 5 days a week and while…read morethere are crowding issues at times, it's understandable because the gym is a very popular one and attracts lots of age ranges and families. I try to use Google Maps to see how busy it is before I go in. I have never once had any personality or customer service issues here & I have always found the staff at the front desk friendly. Any time I have ever raised an issue about bathroom attention or a damaged machine, management has always been very attentive and corrected the issues in a reason amount of time. I love the variety of equipment and the overall layout of the gym. If I had any issues to point out, they would definitely be the tripod users, the clumps of people who gather around machines & barely workout, the overhead music can be too loud at times and the guys who seem to live in the toilet stalls. However, it's one of the best workout facilities I have been fortunate enough to work out at and it's super convenient to go to, so the positives outweigh the negatives by a long shot! Thanks EōS gym staff!!

This particular Club Studio can't decide if it wants to be a day spa or a gym. I was told by a…read moremanager at the front desk that there's no etiquette or rules as to the length of showers the members may choose to take. People can go into the shower and shower for 30 minutes or more and use 8 bottles of spa treatments and leave people standing in line for 15 minutes or more who just wanted to be able to take a quick shower after a workout or being in the pool. Too bad for you! What a joke. This has happened to me numerous times. And the hair washing queens didn't come from the pool, because I swim in the pool. It's just from regular classes. I belong to another Club Studio in a different city, and I've never seen this problem. And I can't even see anything so alluring about the showers at this gym that you'd even want to stay in there for over 30 minutes. In the bathroom, though, Club Studio has "water-saving" motion detected faucets. Serious! If this gives you any idea of what the clientele is like that goes to this place and it doesn't sound like fun having to deal with in the locker room and showers, don't go here. Some good things I can say about this Irvine Club Studio is they do have a clean pool to use, and one of the managers, Julia, was really helpful with dealing with a problem that came up. The trouble with this place is they're just usually too busy trying to cater to the over-entitled instead of doing a good job of running a gym.

I started my fitness journey at F45 Tustin a little over a year ago in 2025, and I can confidently…read moresay that it has been one of the best decisions I have made. The results speak for themselves. The physical changes are noticeable, but more importantly, the consistency, energy, and overall mindset shift have been just as impactful. What truly sets this location apart is the coaching staff and the community. The coaches strike the perfect balance between motivating, encouraging, and keeping things fun (even during the toughest sets). They push you when you need it, support you when struggling, and genuinely care about your progress. Equally important is the community. What started as a group of people working out together has naturally evolved into real friendships. That kind of environment is rare and important to me. If it were not for the great people here, I would have stuck with my other Fitness membership. Speaking of which, in full transparency - I still have another fitness membership elsewhere. However, I have not touched it in months. If one is looking for a place that delivers results, keeps you engaged, and surrounds you with the right people - this F45 Tustin location is the place to be.

F45 workouts are the best part of my day! My usual gym is in Irvine which I LOVE! But I have been…read morewanting to try the Tustin branch out for a while now. They have many class options but they do seem to get busy because they're waitlisted on the app. I managed to passport one Saturday morning. I liked the trainers, the vibe and the music. The DJ arrived for the class after mine so I missed out on that but I still liked the music. I noticed the gym was air conditioned which was different to mine. The instructor's were great at walking around and giving you tips on your workouts. The workout was amazing as always, it's really as hard as you decide to push yourself. So you could have an easy workout by doing body weight exercises or you could lift heavy. Easy parking in the lot up front.

Congratulations, Kyle on your one year anniversary of owning this magnificent gym…read more I've worked out at many gyms throughout my life and Tustin Fitness is, by far, the best!

I go late around 12-2 in the morning and there is always a kind elderly lady who blows the whole gym and then vacuums it all as well.

Only issue here is it gets pretty packed but other than that so clean and the machines are nice and new.

As a founding member of Life Time Fitness, I've been with the gym since day one in 2022. Over the…read moreyears, it's truly become my third space. The facility itself is beautiful, upscale, and consistently clean, with thoughtful amenities like Kiehl's products in the locker rooms that make the experience feel elevated. What really makes this gym stand out, though, are the amazing instructors. Cory for spin, Mariah for mat Pilates, and Haly, Isaiah, and Carmen for Alpha are some of my favorites. Last year, around May 2025, they introduced CTR, a reformer-based Pilates class that was a total game changer for me. I no longer needed to go to a separate Pilates studio. Rob and KO helped build the program, and they were both spectacular. Rob is rarely there now, and KO recently left the gym. In my opinion, Anisa Diaz is an exceptional CTR instructor. Honestly, she's great in every class I've taken with her, including spin and mat Pilates. No two CTR classes with her are ever the same. She's incredibly knowledgeable about the human body, has excellent flow, and every movement feels intentional and challenging in the best way. She consistently brings fresh ideas and new challenges that keep the classes engaging and fun. She truly elevated the entire experience. However, over the past few months, some of her classes have been cut, and I feel the CTR program has started to feel lacking and subpar. Because of that, I've found myself returning to private Pilates studios like Drenched OC, Anodetome, Sol, and Jetset Pilates, which are all fantastic if you're considering a private studio experience. At this point, I mainly take CTR at Life Time only when Anisa is teaching. Overall, I'm still very happy with Life Time. I just wish they would bring more energy -- and Anisa -- back to CTR.

I've been a member for over three years, since before the gym officially opened. The classes and…read moreinstructors are excellent, which is why I've stayed. Unfortunately, the front desk experience has consistently been disappointing. There are always several staff members standing at the front, but when issues are brought up, they tend to repeat the same response instead of actually helping resolve the situation. What's even more frustrating is that when you ask to speak with a manager, suddenly everyone claims to be the manager, yet no one is able to provide a solution. On top of that, membership fees have been increased without proper notice. For a gym at this level, I expected much better customer service and communication.
