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.

Owners Chris and Nancy are so welcoming, professional, and reliable. Plus super clean. Hours are perfect for working peeps. Vibe is friendly and chill. Chris designs the workout with such variety every session, it never gets boring. And so satisfying to see my progress over time, helps me feel good knowing I'm doing something really important for my health. Did a Mud Run in Irvine last weekend with my 26 year old daughter who got tired before I did. Highly highly recommend this gym to anyone who wants to get healthier and aims to stay that way.

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.

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.

Everyone here is respectful and is focusing on their health, which allows for such a safe place to be. The classes are top notch and having two coaches in a class really does make a difference. It's really the only place where they actually correct your form and sometimes they make the exercises harder so you're getting the most out of every workout. I've been her for about two months and haven't had a mediocre experience yet, it's ALWAYS a great class! I've been to most of the popular studios (Nike, OTF, F45, Rumble and etc.), so I have a lot to compare it to. Just come and try it you'll love it!

He's incredibly attentive during our sessions, correcting my form and pushing my goals each week. I'm a competitive person, and I thrive off challenges and raising the bar. I feel super comfortable with Braedon, knowing he will challenge me in a safe and supportive way. My goals with TWD have been to gain weight and gain muscle, and for the first time in my life I actually see and feel the results of my hard work. One of the many perks of working with a trainer is having someone to hold you accountable and help guide you with both the workouts and the nutrition. I've struggled with my own fitness journey throughout my life mostly because I travel so much for work, and I don't have a consistent schedule. Braedon works with me and my hectic schedule regardless if I'm home or on the road. If you're considering getting a personal trainer, I cannot recommend Train With Dave enough. Braedon is incredible, but truly all of the trainers there are amazing. You'll be so grateful if you decide to come to TWD.

The combination of in-person accountability, tracking my workouts and food in the app, and Dom's constant encouragement (yes, even texting me on weekends to remind me to stay on track!) has made all the difference. In about 5 months, I've lost 20 pounds and gained back muscle I'd been missing for years. As I get closer to 40, it was really important for me to rebuild strength for long-term health -- and Dom has helped me do exactly that. The 6 AM sessions are perfect for my schedule, and having others there training alongside me keeps me motivated. If you need structure, accountability, and results, this is the place to go.

The studio is much larger than your typical boutique spot, which gives it a more commercial feel. The instructor was nice and proactive about offering help throughout the session. However, because the class size is large, you lose that personalized, small-group attention. I also noticed the equipment was looking a bit run down and could probably use some maintenance. It was a solid challenge physically, but if you prefer a more intimate environment, this might feel a bit too busy. Good for a sweat, but I personally prefer a smaller studio setting. Come early because it's in a plaza with many businesses and you may need to park in the back lot.

I started training because I wanted to stop feeling weak carrying my groceries, and to build functional strength (for both the present day me and my future 80 y/o self). I've had a spinal fusion and other injuries, so I knew I needed someone who could guide me safely and intentionally. Jonny has been that person and so much more. He's knowledgeable, kind, and dedicated to his clients. He truly wants to see you thrive - and he's also the best hype man when you need that extra push! Before this, I was totally intimidated by gyms. But this space is different. The energy is welcoming, relaxed yet focused, and supportive. Also located right off the 5 fwy, with plenty of parking. If you're thinking about starting, especially if you've dealt with injuries or just feel unsure where to begin - I can't recommend Jonny enough. Built Different is my favorite place to lock in
