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.

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.

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!

I can honestly say joining Hideout Fitness has been one of the best decisions I've made for myself…read morethis year. Walking in for the first time, I was scared. Even though I've always stayed active, strength training felt intimidating to me. I was insecure about where I was starting, worried about how I would look, and unsure if I was even capable of doing some of the things being asked of me. But from day one, there was something different about this place. The environment felt safe, welcoming, and genuinely supportive in a way that's hard to put into words. I've had the chance to work with and interact with multiple coaches, and what stands out most is not just how knowledgeable they are in the art and science of training, but the kind of humans they are. They truly care. They pay attention. They challenge you, support you, encourage you, and somehow know exactly when you need accountability versus reassurance. What Hideout has taught me goes far beyond fitness. It's about learning to embrace obstacles instead of running from them. It's about sitting in discomfort, doing hard things, and realizing that growth often lives on the other side of the moments that challenge us most. They've really given new meaning to the idea that doing the hard thing is often the right thing. And the beautiful part is -- it does feel worth it. There's something incredibly empowering about looking back and realizing, "I worked hard for this. I pushed through. I earned these results." Not just physically, but mentally too. What makes this place special is that it truly feels like a family and community. The coaches pour so much into their clients, and you can feel that they genuinely want to see people succeed in all aspects of life, not just inside the gym. Whether it's the coach you're directly working with or another coach in the gym, they are all there to support and encourage you. I usually come in early to warm up before my session, and every single time I'm greeted by the other coaches, encouraged during my workout, and offered help if I need it. You don't just get one personal trainer here -- you gain an entire family of trainers rooting for you every step of the way. Two months into my journey of becoming stronger, leaner, healthier, and more confident, I can honestly say I'm so grateful I found this community at a time I really needed it. Excited for what's ahead, and so happy I chose Hideout Fitness. Truly the best personal trainers in Irvine.

The habits Jacob helped him build feel realistic and lasting. I could clearly see the structure and accountability Jacob provided - there was always a plan, which removed a lot of the guesswork that usually leads to falling off. His relationship with food also changed in a really healthy way, focusing on protein and consistency without extreme restriction or stress. As a family, it's been inspiring to watch. His commitment naturally set a positive example at home. The 60+ lb weight loss is incredible, but more importantly, this truly feels like a lifestyle change.

The first half of the class was an interval training between walking, jogging, and running. And the second half of the class was strength training. I wish there was more guidance from the instructor for the second half but it was just following what was on the screen like 100 step ups, 90 plank shoulder taps, 80 something, 70 something, etc. It was kind of like F45 style but without the timer and stations. Since there wasnt too much guidance on that part, I felt like I pretty much paid for an interval training on the treadmill. I enjoyed the experience though and would be open to trying out a different class to give it a fair review of if I want to continue or not. I'm still giving it a solid 4 stars though because I pay attention to little details. This studio had HAIR TIES and TAMPONS and even face wash in their bathrooms for us girlies and it's not much but so thoughtful!! Also there are earplugs inside the studio room for those who think its too loud!!! I get headaches when its too loud so I felt so seen and understood by the studio. Also at the end of class, a staff walks around passing out COLD WET TOWELS so you can cool down. These are all little extras that really make a studio stand out so kudos to this place!!
